| Summary: | (258) < carbaryl (260) < methomyl (378) < acephate and 2.5 M sucrose were evaluated for toxicity to adult male corn and 2) gustatory response, 3) lethal concentration, and 4) attracticide formulation. Commercially-available causing mortality, Acephate, carbaryl, lambda-cyhalothrin, concentrations of sucrose and fi-uctose feeding stimulants at concentrations. The same test mixtures were evaluated for cyfluthrin, cypermethrin, DDVP, dimethoate, endosulfan, cyhalothrin (4.4) < profenofos (8.4) < acephate (12.3)< earworms via ingestion. Twenty-four hr LCggs are ranked as effects of seventeen insecticides mixed with two sugar feeding stimulants on feeding behavior and mortality of follows: thiodicarb 2.0ppm Al) < methomyl (2.5) < lambda- for control of adult H. zea formulations of acephate, boric acid, carbaryl, chlorpyrifos, Four laboratory bioassays, including 1) proboscis extension gustatory response. Response inhibition varied between imidacloprid, lambda-cyhalothrin, malathion, methomyl, inhibited proboscis extension below 100 ppm Al inhibition of gustatory response at toxicant concentrations less than 2 hrs for IOX the LCgg concentration. The results malathion (58.2) < carbaryl (73.0). Mean lethal times to malathion, methomyl, profenofos, and thiodicarb mixed with mean lethal time to mortality, were used to investigate the mortality in less than 3 hrs at the 5X LCgg concentration and mortality were estimated for the LCgg concentration and are of these bioassays identify the potential of using feeding oxamyl, profenofos, sulprofos, and thiodicarb, mixed with two pheromone trap captured adult male corn earworms, Helicoverpa ranked as follows: lambda-cyhalothrin (59 niin) < profenofos stimulants mixed with insecticides at reduced concentrations thiodicarb (540) < malathion (780). All toxicants caused this bioassay indicate that none of these insecticides toxicant concentrations up to 10,000 ppm AI (I%) (wt:vol), toxicants, but most insecticides elicited no significant were evaluated for proboscis extension response. Data from zea (Boddie), to screen and evaluate toxicants for use in an |
