“…Aphidius transcaspicus, like other Aphidius species (Sequeira and Mackauer 1992;Perdikis et al 2004;Colinet et al 2005), oviposits and develops in all instars of its host (Li and Mills 2004). When presented in the laboratory with excess hosts of a range of sizes typical of colonies in the field, it showed a slight preference for intermediate instars.…”

“…It appears to be a specialist parasitoid of Hyalopterus species in its native range ), but can develop successfully on more polyphagous aphid hosts in captivity (Wang and Messing 2006). In contrast, A. colemani has been widely introduced around the world (Stary 1995;Takada 1998;Stary 2002) has a broad host range, and much is known of its reproductive and developmental biology, host preferences, and ecology (Jarosik and Lapchin 2001;Stary 2002;Jarosik et al 2003;Jones et al 2003;Lin and Ives 2003;Kalule and Wright 2004;Kavallieratos et al 2004;Perdikis et al 2004;Kalule and Wright 2005;Ode et al 2005;Sampaio et al 2005;Soglia et al 2006;Zamani et al 2006;Zamani et al 2007). Determination of predator preference for different types of prey has received much attention (Singer 2000;Underwood et al 2004;Manly 2006;Taplin 2007).…”

“…Host instar preference among Aphidius spp. appears to be species specific and also to depend on the relative sizes of the different host species attacked (Liu et al 1984;Hagvar and Hofsvang 1991;Weisser 1995;Villagra et al 2002;Perdikis et al 2004;Colinet et al 2005;He et al 2005;Henry et al 2005). Thus, A. colemani showed no preference among instars or morphs of Pentalonia sp.…”

“…The host instar preferences of aphidiine parasitoids are known to be host and parasitoid species specific (e.g. Walker and Hoy 2003;Perdikis et al 2004;He et al 2005;Henry et al 2005), and while invulnerable instars seldom if ever occur, a strong preference for younger instars (e.g. Perdikis et al 2004) may nonetheless contribute to population persistence.…”

Aphidius transcaspicus Telenga (Hymenoptera: Braconidae: Aphidiinae) has been selected for use as a biological control agent against Hyalopterus pruni Geoffroy (Hemiptera: Aphididae) in prune orchards in California. In this study we focus on the host instar preference and functional response of A. transcaspicus. Host instar preference was determined using laboratory arenas by allowing female parasitoids to attack aphids on field-collected leaves of Prunus domestica L. supporting a natural range of H. pruni instars. A relative preference index indicated that A. transcaspicus was 1.4 times more likely to attack intermediate instars (2-4) than 1st or adult instars. The functional response of A. transcaspicus to H. pruni density was determined on enclosed P. domestica shoots in a prune orchard. The functional response to host density was linear (Type I) at the lowest aphid densities, and the asymptotic number of aphids attacked at higher aphid densities was 64.3 ± 6.7 aphids day -1 .

“…Myzus persicae (Sulzer), and particularly Aphis gossypii Glover (Hemiptera: Aphididae), are suitable hosts for the development and reproduction of this parasitoid (van Steenis, 1993;Sampaio et al, 2008), and it prefers to oviposit in the first-and secondinstar nymphs (Perdikis et al, 2004). Although A. colemani is widely used in the biological control of A. gossypii and M. persicae infesting greenhouse crops (van Lenteren, 2003;Yano, 2006), the factors that influence its host selection are poorly studied (Grasswitz, 1998).…”

Abstract. Body size is a main fitness component of insect parasitoids. We assessed the potential influence of maternal size of the parasitoid wasp Aphidius colemani Viereck (Hymenoptera: Braconidae: Aphidiinae) on its ability to parasitize the different instars of Aphis gossypii Glover (Hemiptera: Aphididae) on eggplant and cucumber. In the experiments "small" vs "large" parasitoid females were used. Females oviposited in all instars but more of the smaller hosts were parasitized. Host selection was affected by female size and the larger hosts were more frequently mummified by the large than the small females. Thus, parasitoid female size influenced host selection. This could affect the potential of the parasitoid to exploit populations of aphids that differ in their size structure. The importance of these results in terms of the ecological adaptations of the parasitoid and their implication for biological control are discussed.

Background: Estimating parasitoid abundance in the field can be difficult, even more so when attempting to quantify parasitism rates and theecosystemserviceofbiologicalcontrol thatparasitoidscanprovide.Tounderstandhow'field observed'parasitismrates(in-field mummy counts) of the green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae) translate to 'laboratory observed' parasitism rates (laboratory-reared parasitoid counts), field work was undertaken in Australian canola fields, over the winter growing season.Results: Overall, laboratory observed parasitism was on average 2.4 times higher than field observed parasitism, with rates an average of four-fold higher in fields from South Australia. Total field observed and laboratory observed parasitism rates (OPRs) of M. persicae varied considerably across regions, but less so among fields within regions. As crop growth stage progressed, the incidence of field observed mummies increased. The incidence of total parasitoids reared also increased with crop growth stage, averaging 3.4% during flowering and reaching 14.4% during podding/senescing. Although there was a greater diversity of reared parasitoid species at later crop growth stages, the laboratory OPR was unaffected by parasitoid species. Diaeretiella rapae was the most commonly reared parasitoid, increasing in absolute abundance with crop growth stage.Conclusion: These findings indicate that field mummy counts alone do not provide a clear representation of parasitism within canola fields.
