Spinosyns Cause Aedeagus Eversion in Carpophilus spp. (Coleoptera: Nitidulidae).

During an assessment of various insecticides against sap beetles, Carpophilus sp., it was noted that at least some males everted their reproductive structures (referred to as aedeagus from here forward) when treated with a spinosyn insecticide, spinetoram. This response to spinosyns or other insecticides is not documented in the literature even though sap beetles have been included in numerous insecticide assays and spinosyn insecticides have been in widespread commercial use for >20 yr.

Curative Control of the Peachtree Borer Using Entomopathogenic Nematodes.

The peachtree borer, (Say 1823), is a major pest of stone fruit trees in North America. Current management relies upon preventative control using broad-spectrum chemical insecticides, primarily chlorpyrifos, applied in the late summer or early fall. However, due to missed applications, poor application timing, or other factors, high levels of infestation may still occur and persist through the following spring.
