Lady beetle oviposition behavior in response to the trophic environment (2009, unknown): “Biological Control (2009), leaves versus old aphids on old leaves, C. septempunctata preferentially oviposits near the young ones (Hemptinne et al., 1993; but also see Hemptinne et al., 2000b).”
Lady beetles as predators of insects other than Hemiptera (2009, unknown): “While conspecific eggs may often be highly preferred, eggs of other coccinellids are often avoided by foraging lady beetles (e.g., Hemptinne et al., 2000; Burgio et al., 2002; Sato and Dixon, 2004; Cottrell, 2007; Rieder et al., 2008).”
Predation and cannibalism of lady beetle eggs by adult lady beetles (2005, background): “The alkaloids are synthesized de novo by coccinellids and are reported to be found in all developmental stages (Agarwala and Yasuda, 2001; Ayer and Browne, 1977; Hemptinne et al., 2000a,b,c).”
Suitability of exotic and native lady beetle eggs (Coleoptera: Coccinellidae) for development of lady beetle larvae (2004, unknown): “Hemptinne et al. (2000a) suggest it is highly unlikely that coccinellid larvae would encounter sufficient numbers of coccinellid eggs (e.g., for predation and/or cannibalism) in the field to complete development from first instar to adult.”
Intraguild predation of immature stages of British and Japanese coccinellids by the invasive ladybird Harmonia axyridis (2008, unknown): “Chemical defence has been particularly well studied at the egg stage, where both internal toxins (Pasteels et al. 1973; Agarwala and Dixon 1992) and external feeding deterrents (Hemptinne et al. 2000; Omkar et al. 2004) have been reported.”
