Through this study researchers compared the individual and combined effect of the mobile sticky trap “torito”, wheat straw mulch, soil-based insecticide applications and foliar insecticide sprays on leafminer populations and yield of field grown snow pea. Research was conducted at Xenimajuy?, Tecp?n, Department of Chimaltenango. Treatments consisted of the following insect pest management tactics either individually or in combination: (1) mobile sticky trap (MST), (2) wheat mulch placed at planting, (3) dibrom applications to the soil (insec(s)) and, (4) foliar sprayings of insecticide chemicals (insec (f)) labeled for use in snow peas. These treatments were compared against a check plot, not subjected to any insect management strategy.
The objective of the research was to compare the individual and combined effect of the mobile sticky trap "torito", wheat straw mulch, soil-based insecticide applications and foliar insecticide sprays on leafminer populations and yield of field grown snow pea.
Results from this study show that the combination of different tactics, including the mobile sticky trap and mulch can reduce the need for chemical insecticides for the management of leafminer is snow peas. Incorporation of such novel IPM tactics into current snow pea production practices will facilitate the implementation of quality control programs oriented to enhance the safety of the food supply originating from Central American countries.
