Abstract
Abstract A small plot study was conducted at the Texas A&M Research and Extension Center in Weslsco, Texas, to evaluate the efficacy of selected insecticides for control of leafminers on melons. Plots measuring 1 bed (80 inches) by 25 ft were established in a cantaloupe field in a randomized complete block design with four replications. Treatments were applied with a CO2 pressurized (40 psi) backpack sprayer in a tot3l volume of 25 gal per acre with four 10X nozzles across the row. Plots were sprayed on 7 3nd 16 Jun and samples collected for evalustion on 18 Jun. Samples were collected from five randomly selected plants per plot. On each plant, leaves were examined 3nd counted from the termin3l growth back until mining wss noted. The first lesf with mines and the next leaf back were collected on each plant (10 leaves per plot) and held for emergence. Dsts collected included the number of lesves from the terminal where the first mines were noted and the number of sdult lesfminers and parasites that emerged from samples.
