“…Previously, Rasekh et al (2010a), studying the same strain of L. fabarum, showed that proportional time allocation to within-patch behaviors was not affected by factors such as female age, egg load, day length, encounters with conspecifics, or encounters with previously-parasitized hosts, although with the exception of conspecific encounters, these factors did affect overall patch residence time and numbers of aphids parasitized.

“…Body size could influence parasitoid foraging strategies via effects on other physiological and ecological traits (Godfray, 1994;Roitberg et al, 2001). Foraging strategy may change, as a function of parasitoid age (Weisser, 1994;Rasekh et al, 2010a) and body size could affect foraging behavior via an effect on life expectancy (Fletcher et al, 1994;Ellers et al, 2000).

This study tested effects of maternal body size on foraging behavior and progeny development in a thelytokous population of Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae). Small and large wasps were reared from first and second instar hosts [black bean aphid, Aphis fabae Scopoli (Hemiptera: Aphididae)], respectively, and each was provided with a patch (bean leaf disk) containing either 15 small (second instar) or 15 large (fourth instar) hosts for a 30-min foraging period. Neither body size nor host size affected time allocation to various behaviors within a patch, but second instar aphids produced significantly more mummies than fourth instars. The preferred attack orientation was from the side of the aphid, suggesting wasps were sensitive to the risk of smearing with cornicle secretions. Few wasps developed in fourth instar hosts, suggesting later host instars were somewhat resistant to parasitism. Second instar hosts, the most suitable stage for L. fabarum development, relied more on defensive behavior, specifically kicking and secreting cornicle droplets. Large wasps were more likely to elicit a double cornicle secretion, indicating that aphids graded their response to the size of the attacker. Larger wasps were also more likely to be smeared with cornicle secretion, suggesting they were more vulnerable than small wasps. Although small wasps had smaller eggs than large wasps, there was no effect of maternal egg size on the size of progeny. However, daughters of small females emerged with larger egg loads than daughters of large mothers, and their eggs tended to be slightly smaller, although not significantly. Regression analysis revealed a positive correlation between maternal egg size and progeny developmental time for small and large wasps, and between maternal egg size and progeny egg load for small wasps. These results confirm maternal effects of body size in an aphid parasitoid, and reveal that vulnerability to host behavioral defenses is also body size dependent.

“…Reproduction in A. colemani and L. testaceipes seems to be limited by time because females of these species parasitize a very high number of hosts during the first three days of their life. Indeed, Rasekh et al (2010) report that females of Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae: Aphidiinae) are more likely to be time-limited than egg-limited because they lay most of their eggs early in life. In contrast, the parasitoids P. volucre and P. palitans appear to be egg-limited, i.e., these females need a long lifespan to maximize offspring production.…”

Abstract. Life table data of natural enemies are often used to understand their population dynamics and estimate their potential role in the biological control of pests. Macrosiphum euphorbiae (Thomas) (Hemiptera: Aphididae) is an important pest of several crops and its intrinsic rate of population increase (rm) is 0.282 at 22°C. The life table parameters (immature mortality, developmental time, sex ratio of emerging adults, fecundity and longevity) of Praon volucre (Haliday) (Hymenoptera: Braconidae: Aphidiinae) parasitizing M. euphorbiae were estimated in a climatic chamber at 22 ± 1°C, RH 70 ± 10% and 12 h photophase. Immature mortality was 8.2%, developmental time of males and females was 13.9 and 14.4 days, respectively, and the sex ratio was 0.55 (= fraction of females). Parasitoid fecundity was 504 eggs and longevity 11 days. The net rate of reproduction (R0) was 207.5 females and the intrinsic rate of population increase (rm) 0.281 females/female/day. The time for doubling the population (TD) was 2.45 weeks. P. volucre has a population growth rate similar to that of its host M. euphorbiae and might therefore be a good candidate for the biological control of this aphid.

“…Therefore, it is important to understand the behaviour of the parasitoid in selecting its principal and alternative hosts in a crop, prior to any release in the fi eld (Dorn et al, 1999, Hopkinson et al, 2013. Successful parasitism requires a series of interactions among parasitoids, their hosts and host plants, including habitat fi nding, host location, host acceptance, host suitability and host regulation (Vinson, 1976(Vinson, , 1984Hatano et al, 2008;Rasekh et al, 2010). Parasitoids may respond to semiochemical cues during antennal contact and ovipositor probing (Muratori et al, 2006;Larocca et al, 2007) and volatile chemical compounds emitted by damaged plants (Turlings et al, 1990, Mattiacci et al, 1994, Dicke et al, 2003.…”

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.
