■ Abstract In almost all species of parasitic wasps in the Coccophaginae, a subfamily of Aphelinidae, males have host relationships different from females. In these “heteronomous” species, females are generally endoparasitoids of sternorrhynchous Hemiptera, such as scale insects, mealybugs, and whiteflies. In contrast, males may be hyperparasitoids, developing in or on conspecific females or ot...

A new, biparental species of the genus Encarsia Förster (Hymenoptera: Aphelinidae), E. hera Lahey & Andreason, sp. nov. , is characterized based on morphological and molecular data. The parasitoid was reared from puparia its host, an undescribed grass-feeding aleyrodine Aleurocybotus Quaintance Baker (Hemiptera: Aleyrodidae) collected in Gainesville, Florida. same whitefly newly recorded Ch...

BACKGROUND Species of Eretmocerus Haldeman develop as primary ecto-endoparasites of whiteflies (Rose and Rosen 1992). Currently, the genus Eretmocerus comprises 86 species worldwide, of which 11 species have been previously recorded from Taiwan (Shih et al. 2015). Despite having been recently revised for Taiwan, two new species are here added to the Taiwan fauna. NEW INFORMATION Two new speci...

Three new species of Coccobius Ratzeburg (Hymenoptera: Aphelinidae) are described from China, Coccobius bimaculatus Wang, Huang & Polaszek sp. nov., Coccobius jinshanensis Wang, Huang & Polaszek sp. nov. and Coccobius leptocerus Wang, Huang & Polaszek sp. nov. Coccobius abdominis Huang 1994 and Coccobius furviflagellatus Huang 1994, originally described in Chinese, are redescribed in English an...

BACKGROUND Centrodora is a relatively common and widespread genus of morphologically diverse species, and is the most polyphagous genus known within the Aphelinidae, attacking eggs of insects in addition to pupae of Diptera and Hymenoptera, and nymphs of Hemiptera (Polaszek 1991). There are currently about 60 valid species in the genus, but given its morphological and biological diversity, some...

Shipments of 50,000 commercially reared Aphytis melinus DeBach were obtained from each of the five insectaries that produce and sell this parasitoid to citrus growers in California for control of California red scale, Aonidiella aurantii (Maskell). Shipments were received from each insectary every 2 mo over a period of a year to assess variability in quality through time and between insectarie...

We discuss the potential pros and cons of using importation biological control against the soybean aphid, Aphis glycines Matsumura (Homoptera: Aphididae). Importation of exotic organisms for biological control is never completely risk-free, but the potential negative impacts of not achieving biological control of invasive pests may exceed the risks associated with a biological control introduct...
