Research Project: Susceptibility of Stored Product Insects to Reduced-risk Insecticides

Location: Stored Product Insect and Engineering Research

Project Number: 3020-43000-033-27-N
Project Type: Non-Funded Cooperative Agreement

Start Date: May 1, 2019
End Date: Apr 30, 2022

Objective:
The objective is to cooperate with the scientists at the University of Ljubljana in evaluating reduced-risk insecticides for stored product insects, including the granary weevil, Sitophilus granarius, and the bean beetle, Acanthoscelides obtectus. These insects are serious pests of raw grains and legume crops, respectively.

Approach:
Different techniques will be used to expose adults of stored product insects, including but not necessarily limited to the granary weevil, Sitophilus granarius, and the bean beetle, Acanthoscelides obtectus, on surfaces and substrates treated with reduced-risk insecticides. Mortality of adults will be assessed through direct and indirect exposure, and progeny production after exposure of parental adults. Tests with both species will be conducted by exposing adults on raw crops and on concrete surfaces to simulate exposures on the floor of a storage bin.
