Abstract

The distribution pattern and larval behaviour of the major flower and pod borer Lampides boeticus on vegetable lablab were studied in Bangalore, India. The distribution of eggs and bored flower buds were found to be contagious. Most of the flower buds with pin hole damage had small larva (first and second instar) inside them. Flower buds with medium damage had medium larva (third instar). The flower buds and pods with large damage very rarely harboured larva. The medium and large larvae migrated and caused damage to flower buds and pods. Use of larval behaviour in developing a suitable pest management programme is indicated.

Résumé

Nous a vons étudié à Bangalore la distribution et le comportement des larves de l'insecte perceur Lampides boeticus qui ravage surtout les fleurs et les cosses des haricots légumiers lablab. La distribution des oeufs et des bourgeons percés se trouve contagieuse. La plupart des bourgeons avec des trous d'épingle avaient des petites larves (1er et 2e stades) dedans. Les bourgeons avec des dégâts moyens supportaient des larves de grosseur moyenne (3e stades). Les bourgeons et les cosses avec des grands dégâts abritaient très rarement des larves. Les larves de grosseur moyenne et grande se déplacaient et provoquaient des dégâts considérables aux bourgeons et cosses. Les larves semblaient preferer les bourgeons aux cosses. Sur la base du comportement des larves, nous indiquons des mesures convenables pour arnter les insectes.
