Spinetoram'ın Börülce Tohum Böceği, Callasobruchus maculatus (F.) (Coleoptera: Chrysomelidae: Bruchninae)'a Karşı Rezidüel Toksisitesinin Belirlenmesi

Abstract

In the present study, determination of residual toxicity of Spinetoram solution efficacy was evaluated on chickpeas against adult of Callasobruchus maculatus (F.) under laboratory condition. In laboratory bioassay, C. maculatus adults on chickpeas were exposed to Spinetoram 6, 12, 24, 48 and 60 ppm (mg active substance/l water) concentrations during 1,3,5 and 7 days. %100 paralyze and mortality rate of C. maculatus adults were recorded on surface treated chickpeas by Spinetoram at 48 ppm day of 5 and above concentration (60 ppm) day of 3. Spinetoram LC50, LC90, LC99 values of C. maculatus adults 3.177, 45.230, 79.514 ppm were recorded respectively. At Spinetoram concentrations of 48 and 60 ppm progeny production was less than 3 and 1 adult respectively while at 6, 12 and 24 ppm concentrations progeny production was 29, 13 and 5 adults. In conclusion, this bioassay showed potential ability to use of Spinetoram treatment as a solution on stored products against major stored leguminocae pest C. maculatus was revealed and to be an alternative for conventional synthetic insecticides. © 2019 Namik Kemal University - Agricultural Faculty.
