“…It was noted by several authors (Maeta 1969, Parker et al 1977, Cartwright et al 1982 ) that female ladybirds are parasitized to a higher degree than males, and Davis et al (2006) confi rmed experimentally the preference of British D. coccinellae for ovipositing into female rather than male C. septempunctata hosts. Moreover, British D. coccinellae , having a choice between young (newly eclosed) and old (overwintered) C. septempunctata adults, oviposited preferentially into young ones.…”

“…One of the best understood parasitoids is Dinocampus (Perilitus) coccinellae Schrank (Hymenoptera: Braconidae), whose host preference, life history, ecology, and behavior have been thoroughly investigated (Ceryngier and Hodek, 1996;Majerus et al, 2000a;Okuda and Ceryngier, 2000;Al Abassi et al, 2001;Davis et al, 2006;Firlej et al, 2006;Koyama and Majerus, 2008). Adult coccinellids are preferred, especially older females (Majerus et al, 2000a;Davis et al, 2006), but immature parasitoids have been found in host larvae and pupae (Geoghegan et al, 1998). As a solitary endoparasitoid of adults, D. coccinellae prefers larger species of Coccinellinae (Ceryngier and Hodek, 1996).…”

a b s t r a c tWe review aspects of the life histories of representative enemies of coccinellids (both entomophagous and phytophagous species) and expose both potential and real effects that they have on life parameters of their hosts. Lady beetles are attacked by a variety of natural enemies (bacteria, fungi, mites, nematodes, protozoa, wasps, flies). Few of these enemies have the ability to alter significantly the population dynamics of their hosts. This review should encourage further research to help define the role of natural enemies in the population dynamics of coccinellids. Ultimately, the conservation of beneficial lady beetles and the management of nuisance and pestiferous ones should be major emphases of research on coccinellid-natural enemy interactions.Published by Elsevier Inc.

“…Within a host species, field prevalence levels are higher in females than males (Maeta 1969;Parker et al 1977;Cartwright et al 1982). In laboratory tests, Davis et al (2006) showed that female D. coccinellae have a preference to oviposit into female rather than male adults of C. septempunctata, and that this preference was in addition to the preference the wasp shows for larger hosts in choice tests. As female coccinellids eat more than males (Hodek 1996;Dixon 2000), Davis et al (2006) argue that this preference is adaptive, providing developing wasp larvae with increased resources.…”

Interactions between the parasitoid wasp Dinocampus coccinellae and two species of coccinellid from Japan and Britain

The establishment, spread and increase of the invasive coccinellid Harmonia axyridis Pallas in North America and Britain have coincided with declines in native ladybirds. In Britain, this pattern was predicted soon after H. axyridis was first recorded. However, predictions of the impact that H. axyridis may have on the parasites, parasitoids and pathogens of native coccinellids have been less certain, largely because of uncertainty over whether H. axyridis would become an alternate host for such agents. Dinocampus coccinellae (Schrank) is a braconid parasitoid of ladybirds of the sub-family Coccinellinae. In Japan, this wasp uses both Coccinella septempunctata brucki Mulsant and H. axyridis as hosts, but successfully parasitizes a higher proportion of the former species. Data are here presented that indicate the same is true in Britain, but to a greater extent. This study investigates the interactions of D. coccinellae with C. septempunctata L. and H. axyridis from Japan and Britain. We show that coccinellid activity affects encounter rates with the wasp, with H. axyridis being more active than C. septempunctata in the tests. Escalation rates from investigation to ovipositional attack were higher for C. septempunctata than H. axyridis for both Japanese and British wasps. Wasp emergence was higher, relative to ovipositional attack, from C. septempunctata than from H. axyridis. Wasps did not discriminate between Japanese and British ladybirds of the same species. British wasp eclosion rates were higher from Japanese than from British H. axyridis. We consider both the effect D. coccinellae may have on H. axyridis population demography, and the effect H. axyridis may have on D. coccinellae in Europe.
