Status of Liriomyza spp. (Diptera: Agromyzidae) As An Invasive Pest on Vegetable Plants in Bali

Liriomyza is an invasive insect species not native to Indonesia that attacks various types of vegetable plants in Indonesia. Initially only two species, Liriomyza huidobrensis and L. sativae, were identified to attack vegetable crops in the highlands and lowlands. The attack of these two types of pests caused a very significant loss for vegetable farmers in Indonesia. Recently there are indications of the entry of new species that attack vegetable and ornamental plants in Bali, especially on onions, tomatoes, soybeans, chrysanthemums and cabbage. For this reason, a series of field and laboratory studies need to be conducted to (1) inventory and identify new species of leafminer pest Liriomyza spp. currently invading vegetable plants in Bali, (2) Evaluating the status of new pest species Liriomyza spp. on vegetable crops attacked in the field (3) Mapping the distribution and abundance of populations of new species Liriomyza spp on vegetable plants in Bali, (4) knowing the structure and dynamics of these pest populations in vegetable plantations in Bali, (5) Identifying dominant dominant factors affect the structure and dynamics of the population of Liriomyza spp in Bali (6) Evaluate the role of natural enemies of the parasitoids as a key factor in the structure and dynamics of the population of Liriomyza spp pests in the field. (7) Evaluating the relationship characteristics between host plant vegetation and Liriomyza spp population abundance and parasitoids in the field, (8) Biological characteristics and parasitoid potential as controlling agents of Liriomyza spp, (9) propagation and release of parasitoids to control these pests in the field, (10) ) evaluate the effectiveness of parasitoids as biological control agents in the field. In the first year the study focused on objectives (1) to (6). While the second year research continued with research (7) to (9) and the third year research continued with research (10) and follow-up research from the evaluation results.
