Host Associations

Trissolcus Ashmead (Hymenoptera: Scelionidae) is a cosmopolitan genus of egg-parasitoid wasps associated with stink bugs (Pentatomidae, Scutelleridae, Urostylididae), many of which are important insect pests. Documentation of host associations for these wasps, which we here provide via museum specimens, can support their use as biological control agents of invasive stink bugs. The hosts of seven Trissolcus species are reported from China: Trissolcus cultratus (Mayr) (hosts: Hippotiscus dorsalis Stål, Pentatomidae; Urochela luteovaria Distant, Urostylididae), Trissolcus elasmuchae (Watanabe) (host: Niphe elongata (Dallas), Pentatomidae), Trissolcus japonicus (Ashmead) (hosts: Erthesina fullo (Thunberg), Pentatomidae; Rhaphigaster nebulosa (Poda), Pentatomidae), Trissolcus latisulcus (Crawford) (host: Poecilocoris latus Dallas, Scutelleridae), Trissolcus mitsukurii (Ashmead) (host: Pentatomidae), Trissolcus semistriatus (Nees von Esenbeck) (host: Eurydema sp., Scutelleridae), Trissolcus yamagishii Ryu (host: Niphe elongata (Dallas), Pentatomidae).

The Subject

Accurate identification of parasitoids is crucial for biological control of the invasive brown marmorated stink bug, Halyomrpha halys (Stål). A recent work by Talamas et al. (2017) revised the Palearctic fauna of Trissolcus Ashmead, egg-parasitoids of stink bugs, and treated numerous species as junior synonyms of T. semistriatus (Nees von Esenbeck). In the present paper, we provide a detailed taxonomic history and treatment of T. semistriatus and the species treated as its synonyms by Talamas et al. (2017) based on examination of primary types, molecular analyses and mating experiments. Trissolcus semistriatus, T. belenus (Walker), T. colemani (Crawford), and T. manteroi (Kieffer) are here recognized as valid and a key to species is provided. The identification tools provided here will facilitate the use of Trissolcus wasps as biological control agents and as the subject of ecological studies.

SUMMARYThis review begins with a description of the parasitoid life-style and the ecological and evolutionary factors which generate the remarkable diversity of insect parasitoids. We then describe the various ways that parasitoids have been used in the biological control of insect pests, and survey their success to date. The use of parasitoids remains largely an art, aided by past experience of success and failure. A more fundamental approach, involving basic research and theory, has not as yet contributed significantly to practical biological control. We explore the potential for such a science of parasitoid use and review basic research on parasitoid ecology and evolution which is of particular relevance to biological control. Mathematical models are used to identify and examine those parasitoid and host attributes which lead to successful biological control. Factors such as parasitoid foraging behaviour, fecundity, larval survival and sex ratio are shown to be important in influencing the depression of host populations and/or the stability of host–parasitoid interactions after depression. Multiple release is discussed and a model for inundative release of parasitoids is explored.

Psix striaticeps (Dodd) is an egg-parasitoid wasp previously known only from the Old World. We report this species from twelve counties in Florida, which are the first records in the Western Hemisphere. It was collected in yellow cylinder traps and reared from the eggs of three stink bug species: Nezara viridula L., Chinavia marginata (Palisot de Beauvois), and Piezodorus guildinii (Westwood). A COI barcode analysis found a 100% match between the Floridian population and a specimen from South Africa. The prospects of using Ps. striaticeps as a biological control agent against exotic stink bugs are discussed.

Among the insect pests that affect crucifer crops in Mexico are Delia planipalpis (Meigen) and D. platura (Stein). They are a threat to the production of these vegetables since the damage they cause directly and indirectly affects yield, quality, and commercialization of these crops. Nevertheless, the existence of natural enemies of these dipterans is still unknown. It is fundamental to determine which parasitoids or predators can be considered possible biological control agents in an integrated pest management program. The sampling sites were located in Guanajuato, Puebla, and the State of Mexico, where plants of Brassica oleracea L. var. italica Plenk and capitata L., B. napus L., and Raphanus sativus L. infested with Delia spp. were selected. The symptoms observed were wilting, yellowish, flaccid leaves and individuals less developed than the rest of the crop. These plants were extracted with their root and the surrounding soil. Also, wild crucifers were collected, such as Raphanus raphanistrum L., Brassica campestris L., and Sisymbrium irio L. The first records of Aphaereta pallipes Say (Hymenoptera, Braconidae), Trybliographa rapae (Westwood) (Hymenoptera, Figitidae), and Aleochara bimaculata Gravenhorst (Coleoptera, Staphylinidae) are reported parasitizing the puparia of these anthomyiid flies on cultivated and wild crucifers. This represents only a starting point for the continuous study of these parasitoids, which is needed to consider them useful for the biological control of D. planipalpis and D. platura.
