“…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).…”

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 .

“…A longevidade do parasitóide diminuiu com o aumento da temperatura. No entanto, a longevidade de A. colemani foi maior a 19ºC (18,4), 22ºC (14,1) e 25ºC (8,3) do que a encontrada por outros autores, como nove dias por Monguí et al (1986) a 21ºC, 5 dias por Shelt (1994) a 22ºC, 5 e seis dias por Toussidou et al (1999) a 20°C e 25ºC respectivamente, quatro dias por Gonçalves-Gervásio et al (2001) a 21ºC e seis dias por Soglia et al (2006) a 22°C. O fornecimento aos parasitóides de água na forma de gotículas diariamente e de mel, ao invés de apenas mel ou mel diluído ) e a qualidade do hospedeiro (Roitberg et al 2001) são as causas mais prováveis da maior longevidade do parasitóide, em comparação com os dados da literatura.…”

Aphidius colemani Viereck is among the main natural enemies used for biological control of Aphis gossypii Glover. The objective of the present study was to evaluate the development of A. colemani and the alterations caused by the parasitism in the host A. gossypii in different temperatures and to estimate the thermal requirements of the parasitoid. The experiments were carried out in controlled environmental chambers at 16, 19, 22, 25, 28 and 31 +/- 1 degrees C, 70 +/- 10% RH, and 12h photophase. Second-instar nymphs of A. gossypii were parasitized once and kept individually in glass tubes (2.5 cm x 8.5 cm), containing leaf disc of cucumber (2 cm) and 1% water/agar solution. The development time of A. colemani, from oviposition to mummies (11.9, 9.8, 7.7, 6.4 and 6.4 days) and from oviposition to adult (19.4, 16.2, 12.6, 10.5 and 10.7 days) decreased with the increase of the temperature from 16 degrees C to 25 degrees C. The rates of mummies and the emergence of the parasitoid, and its longevity also decreased with the increase of the temperature. Mummies were not produced at 31 degrees C. The lower temperature threshold of A. colemani was 5.94 degrees C and its thermal constant was 200 degrees-day. The alterations caused by the parasitoid in the A. gossypii host were minimized at 31 degrees C, where 98% of the host did not show symptoms of parasitism and produced nymphs. The temperature of 22 degrees C was optimal for the development time of A. colemani.

“…The parasitoid L. testaceipes showed a preference and greater acceptance of A. fabae over M. persicae, when they were presented both individually and simultaneously, as well as on both host plants. A. colemani and L. testaceipes are generalists but with preferences for aphids on particular species of plants (Soglia et al, 2006, Silva et al, 2008. It is possible that preimaginal learning, such as contact with the mummy, may have occurred and determined host choice preference (van Emden et al, 2008).…”

Abstract. Aphis fabae and Myzus persicae (Hemiptera: Aphididae) are insect pests that damage sugar beet and bean crops. Both are responsible for losses in yield and transmission of viral diseases, and may be present on the same host at the same time. Three parasitoid species, Aphidius colemani, Lysiphlebus testaceipes and Lysiphlebus fabarum (Hymenoptera: Braconidae: Aphidiinae) have the potential to be used as biological control agents against at least one of these species of aphids. As a fi rst step prior to the implementation of a biological control program, our aim was to understand the host selection behaviour of the parasitoids, particularly when both aphids are present. We recorded the host acceptance (number of insertions of the ovipositor / number of antennal contacts), suitability (number of mummies / the number of insertions of the ovipositor) and emergence (number of adults emerging from mummies) of these three aphid parasitoids when parasitizing the two aphids. We also analyzed the effect of the host plant on the host preference of the parasitoid. Females of each parasitoid species (n = 15) were exposed to 20 aphids of A. fabae or M. persicae, or a mixture of these two species of aphids, for 15 min, on a leaf disc of each of the two host plants, sugar beet and bean. Higher host acceptance and suitability were recorded for A. colemani attacking both species of aphid: A. fabae (43 and 46%) and M. persicae (43 and 46%) on beet and bean plants respectively, compared to L. testaceipes and L. fabarum. L. testaceipes and L. fabarum showed a clear preference for A. fabae. L. fabarum accepted M. persicae on both plants only when it was mixed with A. fabae, probably due to a confusion effect. We found that the host plant played a signifi cant role in host acceptance, host suitability. We conclude that A. colemani is the better of the three parasitoids studied for the biological control in bean, and particularly, sugar beet crops.
