Research Project: ECOLOGICAL RAMIFICATIONS OF DEFENSIVE SYMBIOSIS IN AN INVASIVE APHID PEST

Location: Beneficial Insects Introduction Research

Project Number: 1926-22000-024-07
Project Type: Reimbursable

Start Date: Jan 19, 2010
End Date: Aug 31, 2013

Objective:
Although aphid endosymbionts are known to confer resistance to attack by some parasitoid species, very little is known about the impacts such endosymbionts have on biological control of pest aphids. We will determine whether the aphid endosymbiont HAMITONELLA DEFENSA affects parasitism by APHELINUS species being considered for introduction against pest aphids.

Approach:
We will test whether parasitism of APHIS CRACCIVORA by APHELINUS species that are candidates for introduction against soybean aphid is affected by the presences of HAMITONELLA DEFENSA.
