Applied Biology and Ecology ® Melon fly female long maturation ca. 3 weeks ® Melon fly has roosting behavior ® Use trap plants near crops ® Females need protein food ® We can kill many females and males before they attain sexual maturity using a system of trap plantings and attract & kill food baits ® Melon fly has a long lifespan ® Reduce the lifespan of females using a system of trap plantings and attract & kill food baits

Why use bait sprays on melon fly roosting hostplants? Kills females and males where they live § Weekly application increases chances of killing newly emerged flies before they become sexually mature (25 days) § Kills mature flies and avoids additional egg laying (3 -4+ months) §

Trap plants Corn Sudex Castor oil • Plant melon fly roosting hosts– maize, tapioca, sudex, or castor oil weed • Roosting host should be on-farm where the food bait can be applied • Spray once a week, more often during rainy periods Tapioca
