Kin recognition: egg and larval cannibalism in Adalia bipunctata (Coleoptera: Coccinellidae)

AGARWALA B.K., DIXON A.F.G.
N/A

Adult female two spot ladybirds Adalia bipunctata (L.) were reluctant to eat their own eggs. Similarly, second instar larvae avoided eating sibling eggs. However, adult males did not appear to avoid eating eggs they had sired and hungry third instar larvae showed no reluctance to consume younger sibling larvae. These results indicate that female beetles and young larvae are capable of kin recognition. The adaptive significance of this is discussed.
