Resource depression and garden hunting are major topics of archaeological interest, with important implications for understanding cultural and environmental change. Garden hunting is difficult to study using traditional zooarchaeological approaches, but isotopic analyses of animals may provide a marker for where and when people exploited nondomesticated animals that fed on agricultural resources. To realize the full potential of isotopic approaches for reconstructing garden hunting practices—and the impacts of agriculture on past nondomesticated animal populations more broadly—a wider range of species, encompassing many “ecological perspectives,” is needed. We use bone-collagen isotopic compositions of animals (n = 643, 23 taxa, 39 sites) associated with the Late Woodland (~AD 900−1650) in what is now southern Ontario to test hypotheses about the extent to which animals used maize, an isotopically distinctive plant central to subsistence practices of Iroquoian-speaking peoples across the region. Results show that although some taxa—particularly those that may have been hard to control—had substantial access to maize, most did not, regardless of the animal resource requirements of local populations. Our findings suggest that this isotopic approach to detecting garden hunting will be more successful when applied to smaller-scale societies.

This article examines and compares the evolution of animal husbandry practices in several civitates of Gallia Belgica and western Germania Inferior, as documented by archaeozoological data. It focuses on two neighbouring civitates, those of the Nervii and the Tungri, its aim being to explore the factors that influenced diversity in husbandry practices. In general, it appears that cattle played an important role in the Early Roman animal economy of these civitates. There is evidence that large cattle were primarily bred for use as draught animals. At the same time, the intensive processing of cattle on professional butchery sites, and indications of cattle-related craft activities in urban environments, demonstrate that within the market economy animal exploitation was focused on cattle. Nevertheless, several aspects of animal husbandry practices exhibit geographical differences. Evidence of surplus production of pigs in the countryside of Gallia Belgica suggests that different kinds of agricultural specialization existed within the loess belt. There are also differences in the adoption of Roman agricultural innovations in terms of morphological changes in cattle.

This special issue of the European Journal of Archaeology discusses aspects of animal husbandry in a number of provinces of the Western Roman Empire. In this introduction, we describe the general characteristics of animal husbandry in pre-Roman and Roman times to assess any changes that may have occurred after the Roman conquest. The results suggest that the territoriality typifying the first millennium bc had a significant impact on production, resulting in a decrease in cattle size and frequencies across Europe. Nevertheless, not all the regions reacted in the same way, and regional communities that focused their animal production on pigs implemented more sustainable husbandry practices over time. By bringing together studies carried out across Europe, this journal issue highlights the existence of cases of both change and continuity across the Empire, and the (uneven) impact of the market economy on animal husbandry and dietary practices in climatically different regions.

The Roman province of Germania Inferior is characterized geographically by the river Rhine—the border of the Empire—and the forts along it. From the north-west to the south-east, there are significant differences in landscape and type of rural habitation. Whether these differences are also noticeable in animal husbandry forms the subject of this article. Are there any differences in species proportions and slaughter ages between the western and eastern parts of the province, and between urban, military, and rural sites? What does this say about farming and food supply? After presenting an overview of the zooarchaeological data from Germania Inferior, I shall discuss in detail one civitas—the civitas Batavorum, with the best known zooarchaeological dataset within the province. What changes in species proportions and cattle size can be detected over time from this civitas? Is there evidence for inter- and intra-site variability and changes in butchery methods? This article's further aim is to demonstrate what kind of questions a synthetic overview of zooarchaeological datasets can address.

This article reviews aspects of the development of animal husbandry in Roman Britain, focusing in particular on the Iron Age/Roman and Roman/early medieval transitions. By analysing the two chronological extremes of the period of Roman influence in Britain we try to identify the core characteristics of Romano-British husbandry by using case studies, in particular from south-eastern Britain, investigated from the perspective of the butchery and morphometric evidence they provide. Our aim is to demonstrate the great dynamism of Romano-British animal husbandry, with substantial changes in livestock management occurring at the beginning, the end, and during the period under study. It is suggested that such changes are the product of interactions between different cultural and social traditions, which can be associated with indigenous and external influences, but also numerous other causes, ranging from ethnic origins to environmental, geographic, political, and economic factors.

With the conquest of the Iberian Peninsula by the Roman Empire, the different societies in the north, north-west, north-east, east, and centre were grouped into the same province, Hispania Tarraconensis. This article sets out to assess whether this new, Roman, territorial organization affected previous animal husbandry and hunting practices. The taxonomic and osteometric study of faunal remains from ninety-four sites dated between the fifth century bc and third century ad provides an overview of animal husbandry and hunting before and after the Roman conquest. It shows that important changes took place and that this province was differentially exploited in terms of animal husbandry.

Domestic livestock were a crucial part of Mediterranean communities throughout later prehistory. In the first millennium BC, livestock mangement changed, and was changed by, the rise of cities in Italy. Italian prehistory has a rich zooarchaeological tradition, but investigation of the Iron Age has been regionally divided and synthetic works on the Po valley comparatively few. This article presents a pan-regional review of late prehistoric and protohistoric livestock exploitation that considers Northern and Central Italy together for the first time. Zooarchaeological comparison reveals an increase in the use of sheep/goat for secondary products, while cattle and caprines were subject to size changes that distinguish their management from that of pigs. A marked increase in pig husbandry is visible in both regions, but this shift took place earlier and more emphatically in Northern Etruscan centres than in Central Italy. After defining the main changes in animal management during the period under review, this article looks beyond population density to explore the wider environmental, economic, and cultural context of pork consumption and its relation to the development of urbanism in Etruria padana.

This exploratory study aims to understand and improve the performance of Gambia Indigenous Livestock Multipliers’ Associations (GILMA – Fulladu and Saloum) as a way of enabling them to better respond to the challenges faced in fulfilling their institutional responsibilities. Using participatory institutional diagnosis, the GILMA members and experts were able to examine their associations and to stimulate collective reflection as a means of making the associations more efficient and effective. The findings of this diagnosis showed that functioning of both GILMAs was closely linked to the operations of their technical partners. This resulted to GILMAs which clearly lack defined vision and mission. Main issues to address include capacity development of GILMA's executive committee in terms of institutional management, group facilitation, participatory planning, effective strategies for partnership and ownership. Overall, this study developed pathways for revitalizing GILMAs into vibrant and self-sustaining indigenous ruminant livestock multipliers’ associations that can effectively carry out specific roles and responsibilities within the three-tier Open Nucleus Breeding Scheme of the International Trypanotolerance Centre.

Pigs have socio-economic and cultural importance to the livelihood of many Bhutanese rural communities. While there is evidence of increased religious disapproval of pig raising, the consumption of pork, which is mainly met from imports, is increasing every year. Pig development activities are mainly focused on introduction of exotic germplasm. There is an evidence of a slow but steady increase in the population of improved pigs in the country. On the other hand, indigenous pigs still comprise 68 percent of the total pig population but their numbers are rapidly declining. If this trend continues, indigenous pigs will become extinct within the next 10 years. Once lost, this important genetic resource is largely irreplaceable. Therefore, Government of Bhutan must make an effort to protect, promote and utilize indigenous pig resources in a sustainable manner. In addition to the current ex situ conservation programme based on cryopreservation of semen, which needs strengthening, in situ conservation and a nucleus farm is required to combat the enormous decline of the population of indigenous pigs and to ensure a sustainable source of swine genetic resources in the country.

Cerconota anonella is the most important pest of the Annonaceae in the Neotropical region for larval damage, which can result in 60 to 100% losses in fruit production. However information on the pest's biology is scarce. This research compared different artificial diets for rearing C. anonella under laboratory conditions (25.0 ± 1.0 °C; 60 ± 5.0% RH and 14 h photophase). Five diets were compared: A (bean, soybean meal, wheatgerm, casein and yeast), B (maize flour, wheatgerm and yeast), C (wheatgerm and casein), D (wheatgerm and soybean) and E (wheatgerm and soybean). In diet E, the amount of wheatgerm was higher than that in dietD. The results indicated that diet E was the most suitable one for the development of C. anonella.

Studies were conducted from 1993–1995 at Samanko, Mali, on rearing and pheromone trapping of Busseola fusca Fuller (Lepidoptera: Noctuidae), and on the insecticidal effect of extracts of Jatropha curcas (Euphorbiaceae) on B. fusca and Sesamia calamistis Hampson (Lepidoptera: Noctuidae). A technique for mass rearingof B.fusca larvae on a chickpea and sorghum leaf-based meridic diet was developed, requiring about 10 g of diet per larva. An average of 7.3 successive generations were obtained per year. Pupal and larval mortalities were less than 15%. Oviposition was obtained on artificial substrates, with a fecundity of 300–500 eggs per female. Laboratory tests were conducted with diets in which extracts of nuts of J. curcas had been added. A 100% larvicidal effect was obtained with B. fusca and S. calamistis at 0.01% and 1% crude oil concentration respectively, and with 0.025% of the phorbol ester fraction on S. cahmistis. Trapping experiments using traps made of aluminum trays baited with synthetic pheromone showed that B. fusca male moths flights could be satisfactorily monitored. An improvement of traps and/or pheromone effectiveness is, however, necessary before their use as a control method.

The aim of this study was to monitor the reproductive cycle of female Heterobranchus longifilis under tropical pond conditions in order to optimize controlled spawning. Three experimental groups were set up: The first group (I) consisted of adult females transferred from their natural habitat to ponds. The second experimental group (II) consisted of breeders that adapted to husbandry conditions for at least one year. The third set of females (III) was produced under hatchery conditions. Females of the natural population served as controls. Over a one year period blood samples were taken from the individually marked females on a biweekly basis. If ripe eggs were found at the sampling time, females were stripped, the eggs were fertilized and hatched artificially. None of the feral breeders that were transferred to ponds during their natural breeding season could be stripped during that year. The breeding season of both groups II and III started in February. Seasonal changes in egg output showed a maximum between April and July. Egg production of group III was generally higher. The time interval between two strippings of the same female was 6 weeks. Viable eggs were obtained from the adapted feral breeders until August, whereas the breeding season of the hatchery-raised females extended to October. Two thirds of the hatchery-raised females were stripped four or more consecutive times. Throughout the entire season high hatching rates of normal larvae were obtained. Seasonal profiles of the gonadal steroids testosterone and estradiol-17β reflect the annual changes in sexual activity of female Heterobranchus longifilis in tropical pond culture, exhibiting maximum values during the breeding times of each group and being lowest during resting periods.

Hand-stinging and mass exposure methods of rearing the parasitoid Cotesia flavipes Cameron (Hymenoptera:Braconidae) on the stem borer host, Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae), were compared. The proportion of hosts successfully parasitised, progeny production, proportion of female progeny, and host mortality did not differ between the two methods. However, there was evidence of superparasitism of mass-exposed hosts. Releases of C. flavipes as adults and as cocoons were both effective methods for field colonisation of the parasitoid. A device for the release of C. flavipes in the cocoon stage is described.

When reared in the greenhouse, the rice skipper, Pelopidas mathias (F.) (Lepidoptera: Hesperiidae), laid 2–3 times fewer eggs than Held collected females held under the same conditions. Adult-emergence and mating/oviposition cages may have to be placed in environmental chambers with controlled temperature and photoperiod to achieve normal mating and oviposition. Rearing required a mating'oviposition-cage at least 3 m3 in volume and honey as sustenance. Eggs and larvae were held in larval rearing cages and pupae were removed and held in adult emergence cages. Maximum oviposition occurred at dawn. The total developmental period from egg to adult was 34.7 days. P. mathias demonstrated a greater oviposition preference for rice and Paspalum conjugatum Berg, than for Dactyloctenium aegyptium (L.) Willd. P. mathias successfully developed to adulthood on all 24 species of Poaceae tested, exclusive of rice, but did not survive on the six species of Cyperaceae tested. Low populations of P. mathias in rice can be attributed to its low fecundity, wide host range, and equal adaptability to upland and lowland environments, thus diluting its number.

The composition and preparation of an artificial diet for the coffee berry borer, Hypothenemus hampei is described. Ten generations were obtained without any significant change in fecundity. Development at 25°C on this diet was similar to previously reported work using coffee berries. One female reared on this diet lived for 380 days. This diet will permit investigations into the genetics of insecticide resistance, potential biopesticides and other research, requiring a convenient laboratory rearing system.

The coffee berry borer, Hypothenemus hampei, which originates from Africa, is one of the most serious pests of commercial coffee and is now present in most of the major coffee growing parts of the world. Quite recently, this beetle spread into Mexico and Ecuador and is now causing serious economic losses in these two countries. In 1985, a classical biological control programme was started to control the pest using the bethylid, Prorops nasuta and other hymenopterous natural enemies from Africa. During the programme, various studies were conducted in Kenya on P. nasuta and H. hampei including their field distribution and life history. A technique of rearing and screening P. nasuta against plant diseases was developed and several shipments have now been made to Ecuador and Mexico. In 1988 a continuous laboratory culture of P. nasuta had been established in Ecuador and the wasp was also reported to be reproducing in sleeves cages in the field.

A taxonomie inventory is under way in South America to identify the major natural enemies of the cassava green mites, Mononychellus tanajoa. Special emphasis is being given to the Phytoseiidae, important predators of phytophagous mites feeding on cassava. Several insect predators and more than 40 species of Phytoseiidae have been identified in Colombia; Typhlodromalus limonicus and Neoseiulus anonymus are the most frequently found species. Selected aspects of the bionomic studies on T. limonicus and N. anonymus are presented, and methods of rearing numerous phytoseiid species are discussed. Five species are being reared at the Centro Internacional de Agricultura Tropical (CIAT) and have been sent to the International Institute of Tropical Agriculture (IITA) in Nigeria. Surveys for natural enemies will include most cassava-growing areas of Central and South America. Selection of exploration sites and timing of explorations will be guided by matching agrometeorological zones in the country of origin with those in the proposed country of introduction. Duration of dry periods, rainfall patterns and temperature are particularly important considerations in the matching.
