An Egg Parasitoid Efficiently Exploits Cues From a Coevolved Host But Not Those From a Novel Host

open access: yesFrontiers in Physiology, 2019
Egg parasitoids have evolved adaptations to exploit host-associated cues, especially oviposition-induced plant volatiles and odors of gravid females, when foraging for hosts.

The Discovery of Trissolcus japonicus (Hymenoptera: Scelionidae) in Michigan [PDF]

open access: yes, 2019
The invasive brown marmorated stink bug, Halyomorpha halys (Stål), is a pest of growing economic importance in the United States, the control of which currently relies on pesticide applications.

The evolution of gregariousness in parasitoid wasps [PDF]

open access: yes, 1998
Data are assembled on the clutch-size strategies adopted by extant species of parasitoid wasp. These data are used to reconstruct the history of clutch-size evolution in the group using a series of plausible evolutionary assumptions.

Cold storage-mediated rearing of Trichogramma evanescens Westwood on eggs of Plodia interpunctella (Hübner) and Galleria mellonella L.

open access: yesPLoS ONE, 2021
The egg parasitoid Trichogramma evanescens Westwood is considered as an efficient biological control agent for managing several lepidopteran pests and it is widely distributed throughout the world. Mass rearing protocols of parasitoids that are currently

Surveys in northern Utah for egg parasitoids of Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) detect Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) [PDF]

open access: yesBiodiversity Data Journal, 2020
The highly polyphagous and invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), has become a significant insect pest in North America since its detection in 1996.

Effect of Short Term Cold Storage on the Quality of \u3ci\u3eTrichogramma Brassicae, T. Cacoeciae\u3c/i\u3e, and \u3ci\u3eT. Evanescens\u3c/i\u3e (Hymenoptera: Trichogrammatidae) [PDF]

open access: yes, 2018
Trichogramma cacoeciae Marchall, T. brassicae Bezdenko and T. evanescens Westwood (Hymenoptera: Trichogrammatidae) could be useful in biological control programs of agricultural insect pests.

Choosy egg parasitoids: Specificity of oviposition‐induced pine volatiles exploited by an egg parasitoid of pine sawflies

open access: yesEntomologia Experimentalis et Applicata, 2005
AbstractGeneralist parasitoids are well‐known to be able to cope with the high genotypic and phenotypic plasticity of plant volatiles by learning odours during their host encounters. In contrast, specialised parasitoids often respond innately to host‐specific cues.

Field Tests of Kairomones to Increase Parasitism of Spruce Budworm (Lepidoptera: Tortricidae) Eggs by \u3ci\u3eTrichogramma\u3c/i\u3e Spp. (Hymenoptera: Trichogrammatidae) [PDF]

open access: yes, 2017
Hexane extracts of spruce budworm, Choristoneura fumiferana, moth scales, applied at 0.04 moth-gram equivalents/branch and at 0.06 moth-gram equivalents/tree, failed to increase parasitism rates of Trichogramma spp.

Development, Survival and Phenology of the Sweetclover Weevil Parasitoid, \u3ci\u3ePygostolus Falcatus\u3c/i\u3e (Hymenoptera: Braconidae) [PDF]

open access: yes, 2018
Biennial sweetclovers were widely used for soil improvement and as for- ages in the first half of the 1900s. The introduction of the sweetclover weevil, Sitona cylindricollis, caused a drastic decline in sweetclover acreage.
