Four types of trap, yellow water, yellow sticky board, bottle with 20% protein hydrolysate, and funnel with 10% casein hydrolysate, were field-tested to control Liriomyza huidobrensis (Blanchard) in the coastal region of Peru. The yellow sticky boards were the most effective in trap capture with a mean of 1193.92 L. huidobrensis per week. The male:female capture ratio was 16:1.

Five parasitoid species, Halticopiera patellana, Chrysocharis phytomyzae, Chrysocharis sp., Diglyphus sp. and Opius sp., were also trapped. A significant negative correlation (r = —0.607 at P < 0.05) was observed for female leafminer capture vs temperature. Wind velocity was positively correlated with parasitoid capture (r = 0.509 at P < 0.05). The population of adult L. huidobrensis was significantly lower (P < 0.05) in plots with yellow sticky boards. Yields in plots with yellow sticky boards and those treated with insecticides were similar and significantly higher (36%) than check plots..

Quatre types de pièges ont été testés en champ afin de contrôler le Liriomyza huidobrensis (Blanchard) dans la région côtiére du Pérou: le piége jaune a eau, le piége jaune gluant, le flacon avec 20% de protéine hydrolysée et l’entonnoir avec 10% de caséine hydrolysée. Le plus efficace s’est avéré etre le piège jaune gluant avec une moyenne de 1193.92 L. huidobrensis par semaine. La proportion mâle/femelle etait de 16:1.

Cinq especes parasitaires ont également été capturees: Halticoptera patellana, Chrysocharis phytomyzae, Chrysocharis sp., Diglyphus sp. et Opius sp.. On a observé une correlation négative (r = —0,607 avec P < 0.05) entre la capture des insectes mineurs de feuilles femelles et la température, et une corrélation positive (r = 0.509 avec P < 0.05) entre la vitesse du vent et la capture des parasites. La population de L. huidobrensis adulte était nettement plus faible (P < 0.05) dans des parcelles nanties de piéges jaunes gluants. Les rendements enregistrés dans les parcelles nanties de pieges jaunes gluants ou traitées aux insecticides etaient similaires et nettement plus éléves (28.57%) que dans les parcelles témoins.
