Using pheromones and other safe and sustainable management strategies to reduce losses from insect pests and plant diseases on vegetable and leafy brassicas in Southeast Asia
Project
Project code: JKI-ÖPV-08-1312
Contract period: 01.11.2014
- 31.03.2017
Purpose of research: Applied research
The project goal is to improve the livelihood of farmers in Cambodia, Lao PDR and Vietnam and to increase the availability of wholesome vegetables with reduced risk of pesticide contamination through sustainable vegetable legume and leafy brassica production systems in the target countries. The project will deliver the following outputs in the target countries: (1) Major insect pests and plant diseases on yard-long bean and leafy brassicas identified and their genetic diversity assessed, (2) IPM component technologies developed for major insect pests and plant diseases on yard-long bean and leafy brassicas, (3) Farm- and policy-level constraints to, and opportunities for, IPM adoption identified, (4) Newly developed IPM strategies validated and existing IPM strategies promoted against major pests and plant diseases on yard-long bean and leafy brassicas, and (5) Research and development capacity of scientists and extension personnel from collaborating national agricultural research and extension system (NARES) and farmers developed. The project will achieve the outputs through (i) characterisation of genetic diversity of target pests and plant pathogens in the target countries to provide data needed to develop effective IPM strategies, (ii) development of pheromone and kairomone lures for major pests, which will enable the trap-based pest monitoring and mass-trapping, (iii) identifying species-specific parasitoids and evaluating them together with entomopathogens and natural plant-based pesticides, (iv) identifying varieties of yard-long bean and leafy brassicas with durable resistance to major diseases and incorporating them into the IPM strategies, and (v) use of simple protective structures to reduce pathogen transmission, exclude insect pests and protect the plants from heavy rain. Humboldt-Universität zu Berlin and the Julius-Kühn Institut are working predominantly on the identification and characterization of pheromones and kairomones of selected pests.
The overall goal of this international project is to improve the livelihood of fanmers and increase the availability of wholesome vegetables with reduced risk of pestleide contamination through sustainable vegetable legume and leafy brassica production systems in the target countries Cambodia, Lao PDR and Vietnam. Two insect pests are prioritized in the study: Piefis rapae and Piefis sfrio/ata, because they require more basic research, since some IPM component technologies have already been developed for other abundant insects pests such as Maruca vitrata, Spodoptera litura, aphids, and thrips. The chemical components and the ratio of the P. rapae aphrodisiac pheromone and the P. stfiolata aggregation pheromone in population of different Asian geographic regions will be analyzed in comparison to the European population. Compounds identified with GC-MS will be tested for their activity in GC EAG studies and wind-tunnel/olfactometer experiments. The final goal is the development of pheromone and kairomone lures for the major pests in leafy brassica and tegumes, which will enable the trap-based pest monitaring and mass-trapping.
