“…Information on physiological host range (ability to successfully develop in a host) is ideally accompanied by knowledge of ecological (realized) host range and parasitoid behavior, because maximumchallenge laboratory conditions often overestimate the likely impact and host range in the field (e.g., Haye et al 2005, Jenner et al 2014. Given that hundreds of pentatomid species occur in the U.S., some of which are predatory species, extensive host range testing of Asian Trissolcus, including T. japonicus, as candidate agents for H. halys has been in progress but is not yet completed.…”

Trissolcus japonicus (Ashmead) is an Asian egg parasitoid of the brown marmorated stink bug, Halyomorpha halys (Stål). It has been under study in U.S. quarantine facilities since 2007 to evaluate its efficacy as a candidate classical biological control agent and its host specificity with regard to the pentatomid fauna native to the United States. A survey of resident egg parasitoids conducted in 2014 with sentinel egg masses of H. halys revealed that T. japonicus was already present in the wild in Beltsville, MD. Seven parasitized egg masses were recovered, of which six yielded live T. japonicus adults. All of these were in a wooded habitat, whereas egg masses placed in nearby soybean fields and an abandoned apple orchard showed no T. japonicus parasitism. How T. japonicus came to that site is unknown and presumed accidental.

“…Based on the knowledge that both D. pulchellus (Jenner et al, ) and C. albifrons (Arthur, ; Miall et al, ) require non‐host food sources to maximize their ability as primary (i.e., D. pulchellus & C. albifrons ) and secondary (i.e., C. albifrons ) parasitoids, we predicted that parasitoids provided with sucrose, floral nectar and extrafloral nectar resources would live longer, produce more offspring and kill more hosts than those provided only with water, hosts and the crop plant. Previously observed differences in life‐history traits of the two parasitoids (Jenner, Kuhlmann, Miall, Cappuccino, & Mason, ; Miall et al, ; Noyes, ) indicated that there could be different temporal effects of sugar provisioning on D. pulchellus and C. albifrons . Thus, we examined only the direct advantages of flowering plant and sugar provision on each of these parasitoids, a first step to understanding how this floral addition could affect the biological control effects of these parasitoids in a more complex ecological system.…”

Resources added to agroecosystems to enhance biological control are potentially available to multiple members of the resident insect community—not only the biological control agents for which the resources are intended. Many studies have examined the effects of sugar feeding on the efficacy of biological control agents. However, such information is lacking for other, interacting species such as facultative hyperparasitoids, which may contribute to pest suppression but can also interfere with introduced biological control agents. Under greenhouse conditions, we tested the direct effects of sugar and nectar provisioning on the longevity, host‐killing impact and offspring production of two pupal parasitoids associated with leek moth, Acrolepiopsis assectella: the introduced biological control agent, Diadromus pulchellus, and the native facultative hyperparasitoid, Conura albifrons. Adding sucrose, buckwheat or a combination of buckwheat and common vetch to a sugar‐deprived system (potted leek plants in cages) increased parasitoid longevity and resulted in higher leek moth parasitism and mortality compared to water or common vetch treatments. However, the two parasitoid species exhibited a distinct temporal response to the treatments, likely influenced by differences in their life histories. This study provides insight into how integrating conservation biological control techniques could affect the success of a classical biological control programme.

“…Several biological attributes affect the potential effectiveness of parasitoids, such as development rate (Bürgi & Mills, 2013), larval survival (Qiu, Zhou, Luo & Xu, 2012), adult longevity (Winkler, Wäckers, Bukovinszkine-Kiss & Van Lenteren, 2006), sex ratio (Berndt & Wratten, 2005), fecundity (Jervis, Moe & Heimpel, 2012;Wakefield, Bell & Gatehouse, 2010), host specificity (Jenner, Kuhlmann, Miall, Cappuccino & Mason, 2014;Murray, Withers & Mansfield, 2010), and functional response (Latham & Mills, 2012;Luo, Li, Lu, Zhang, Haye, Kuhlmann & Wu, 2014b). The evaluation of a biological control agent requires the collection of detailed A c c e p t e d M a n u s c r i p t information on its life history traits, including aspects of immature stage development and the female's reproductive strategy (Haye, Broadbent, Whistlecraft, & Kuhlmann, 2005;Jervis et al, 2012).…”

Effect of temperature on the reproductive biology of Peristenus spretus (Hymenoptera: Braconidae), a biological control agent of the plant bug Apolygus lucorum (Hemiptera: Miridae) Running title: Effect of temperature on the reproductive biology of Peristenus spretus Peristenus spretus Chen et van Achterberg (Hymenoptera: Braconidae), a parasitoid of the plant bug Apolygus lucorum (Hemiptera: Miridae), has been studied for use in augmentative biological control in China. Under laboratory conditions, we explored the development, survival, age-specific and potential lifetime fecundity, oviposition period, and progeny sex ratio of P. spretus reared at six constant temperatures (15, 19,A c c e p t e d M a n u s c r i p t Downloaded by [UQ Library] at 00:35 14 June 2015 23, 27, 31, 35 °C) on the second instar nymphs of A. lucorum. At 15°C, male and female P. spretus took 48.7 ± 0.3 and 52.5 ± 0.3 days to complete their immature development, while developmental time was reduced by more than half at 23 and 27 °C. The parasitoid can only develop to the larval stage at 31 °C and neither larva or pupa survived at 35 °C. The estimated lower developmental threshold of the immature stage was 7.3 °C. When parasitoid adults were exposed at 15 °C, females laid 90% of their eggs at first 19 days of oviposition and had an extended reproductive life. In contrast, females held at 27 °C laid most of their eggs (90%) in their first of 10 days of oviposition and had shorter longevity. The highest potential lifetime fecundity of P. spretus was 671.2 ± 34.7 SE eggs produced over 23.4 ± 1.4 SE days at 23 °C. At 15, 19 and 23 °C, sex-ratios of reared parasitoids were male biased, but at 27 °C there was no male bias.
