Research Project: Transcriptome Analyses of Rice Stink Bugs to Facilitate Identification of Pheromone Biosynthetic Pathways and RNAi-Based Biopesticide Development

Location: Invasive Insect Biocontrol & Behavior Laboratory

Project Number: 8042-22000-288-18-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Feb 20, 2017
End Date: Feb 19, 2022

Objective:
The objective of this research is to characterize expressed gene profiles and patterns in order to develop RNAi-based molecular biopesticides for control of potentially invasive rice stink bug pests abundant in Brazil. Expression of genes which encode enzymes responsible for biosyntheses of pheromones will also be targeted. Pheromones of rice stink bugs will be identified and used for monitoring. Although the rice stink bugs that occur in Brazil are exotic in the U.S., development of molecular biopesticides and pheromone monitoring tools will help greatly in detection and control of these potentially invasive species should they be introduced via trade, as well as related species that are already pests in the US.

Approach:
ARS scientists will employ our expertise and new technologies to characterize transcriptomes of pest insects such as we demonstrated recently for brown marmorated stink bug and harlequin bug. ARS scientists have also expertise in identification and synthesis of pheromones. EMBRAPA isolated and identified pheromones from at least three rice stink bug pests and has capabilities of conducting laboratory and field bioassays to evaluate developed technologies.
