Larvae of aphidophagous ladybirds leave a cue in their tracks that deters oviposition. The influence of relatedness on this behaviour is for the first time explored in this paper. Two-spot ladybird females (Adalia bipunctata L.) under different conditions (young and naive, young and experienced, and old and naive) were exposed either to (i) clean filter paper, (ii) filter paper contaminated with unrelated larval tracks or (iii) filter paper contaminated with related larval tracks from their offspring. Oviposition time was recorded during nine hours. Oviposition was inhibited by larval tracks, and was more so by related than unrelated ones. Experienced females showed the same behaviour but with lower intensity. With old females, response was not significant with any type of larval tracks. This is the first report of the effect of relatedness on a ladybird's response to larval tracks.

In this article we seek to show that prevailing ideological viewpoints on Black health misinterpret Black behavior, and that dominant racial ideologies themselves have negative health effects on African American communities. Second, we show that public policies and practices reflecting prevailing ideological viewpoints harm African American communities. Together, these ideologies and policies undermine Black health by adversely impacting the immune, metabolic, and cardiovascular systems, fueling the development or progression of infectious and chronic disease. Third, we argue that health reform pursued within the same prevailing ideological viewpoints that misinterpret Black health problems have limited effectiveness. We argue for culturally appropriate public policies that value African American social perspectives and coping mechanisms. We suggest that substantive health reform is best pursued through a democratic movement that challenges dominant ideological commitments.
