Part 1: Impact assessment of the duration of exposure to environmental conditions and predation of two cohorts of trichogramma released in bulk
Part 2: Evaluating two bulk trichogramma releases by drone
Four replicates of the three treatments in a randomized complete block design were established on 0.2 ha plots at least 150 m apart.
Part 3: On four farms, two of which are organic, the most effective release strategy based on the results of Part 2 were compared with an untreated control. Four replicates of the three treatments in a randomized complete block design were established on 3 ha plots (0.5 ha plots for the controls) at least 150 m apart. The following parameters were measured: trichogramma quality, number of male corn borers captured in the traps, number and GPS coordinates of corn borer eggs and sentinel eggs on the plants, trichogramma parasitism and emergence rates, and crop damage.
Part 4: Economic analysis comparing control strategies (insecticides, Trico cards, and trichogramma releases by drone)
From 2016 to 2018
Pest, weed, and disease control
This project will encourage growers to adopt biological control methods to deal with the corn borer and, in doing so, lead to reduced pesticide use.

This project proposes ways of using legume intercrops to control vegetable pests (insects, diseases, and weeds) while increasing soil productivity and quality and economic yields.

This project aims to explore and experiment new approaches and ways to preserve, develop, and enhance the MRC’s bio-food sector, and reduce or eliminate the water deficit on the island.
The aim of the project was to measure the performance and water requirements of eight potato cultivars under commercial production conditions.
