The biological efficacy of pear ester on the activity of Granulosis virus for codling moth
Journal of Pest Science 81 (1), 29-34
Abstract: Ethyl (E,Z)-2,4-decadienoate (pear ester) is an adult and larval kairomonal attractant for Cydia pomonella (L.) (Lepidoptera: Tortricidae). The possibility of using a microencapsulated formulation of pear ester (DA-MEC, a.i. 5%, Trécé Inc.) to interfere with the host location behaviour was evaluated. Laboratory leaf disc bioassays and field efficacy trials were carried out on apple to determine the potential of improving the insecticidal performance of the granulovirus of C. pomonella (CpGV) by co-mixing with pear ester in a sprayable formulation. In laboratory bioassays, adding DA-MEC at low doses of CpGV insecticide increased the larval mortality as a function of time. The field tests performed revealed a significant effect of the blank DA-MEC formulation in reducing fruit injury compared to an unsprayed control.
