PESTICIDE SUSCEPTIBILITY OF CYBOCEPHALUS NIPPONICUS AND RHYZOBIUS LOPHANTHAE (COLEOPTERA: CYBOCEPHALIDAE, COCCINELLIDAE)

Fortuitous Establishment of Rhyzobius lophanthae (Coleoptera: Coccinellidae) and Aphytis lingnanesis (Hymenoptera: Encyrtidae) in South Texas on the Cycad Aulacaspis Scale, Aulacaspis yasumatsui (Hemiptera: Diaspididae)

Susceptibility of lady beetles (Coleoptera: Coccinellidae) to entomopathogenic nematodes.

We investigated differential susceptibility of lady beetles to entomopathogenic nematodes, for two reasons: (1) to estimate potential nontarget effects on natural lady beetle populations, (2) to compare the susceptibility of exotic versus native lady beetle species. We hypothesize that successful establishment of some exotically introduced arthropods may be due, in part, to a lower susceptibili...

Van Driesche et al.: Euonymus Scale Natural Enemies 1 RELEASE, ESTABLISHMENT AND SPREAD OF ASIAN NATURAL ENEMIES OF EUONYMUS SCALE (HOMOPTERA: DIASPIDIDAE) IN NEW ENGLAND

Between 1990 and 1995, the USDA/APHIS National Biological Control Laboratory in Niles, MI, Texas A&M University, and the University of Massachusetts conducted a biological control introduction program against the Asian diaspidid scale insect Unaspis euonymi (Comstock), a pest of woody landscape plants. Two species of predators ( Chilocorus kuwanae Silvestri, Coleop.: Coccinellidae and Cybocepha...

A review of the Japanese Cybocephalidae (Coleoptera: Cucujoidea).

The Cybocephalidae of Japan is taxonomically treated. The following four species are recognized: Cybocephalus (Cybocephalus) nipponicus Endrödy-Younga, 1971, C. (C.) politissimus Reitter, 1898, C. (C.) chlorocapitis sp. nov., and Pastillus eminentithorax sp. nov. Also, species of the genus Pastillus are first recorded from the Palaearctic Region, and C. (C.) politissimus is first recorded from ...

Susceptibility of a native and an exotic lady beetle (Coleoptera: Coccinellidae) to Beauveria bassiana.

The exotic multicolored Asian lady beetle, Harmonia axyridis, became established and recently spread across much of North America and southern Canada. In a habitat now used by both the invading H. axyridis and a native lady beetle, Olla v-nigrum, we discovered that the native lady beetle was commonly infected by Beauveria bassiana; whereas, the exotic H. axyridis, was not. Laboratory assays rev...
