“…For instance, resistance to OPs in the cotton aphid, Aphis gossypii Glover, has been associated with high carboxylesterase activity, and elevated concentrations of esterases were often associated with Ðtness costs. 35,36 In addition, we found a limitation of our assay, in that we only measured one component of Ðtness, egg-laying. Although fecundity is a readily measurable and important component of Ðtness, it is not necessarily an accurate indicator of overall Ðtness.…”

: Toxicity assays with tebufenozide, the Ðrst commercial non-steroidal ecdysteroid agonist, against a laboratory strain of the beet armyworm, Spodoptera exigua (Hu bner), demonstrated the promise of this new compound for the control of this important pest. Experiments to select insects artiÐcially from the laboratory strain by continuous exposure of larval instars to corresponding LC 25 doses of tebufenozide for over 12 generations 14È15 months), (G 0 ] G 12 : revealed no loss in susceptibility to the insecticide for up to Ðve generations. Moreover, retention and fate of 14C-labelled tebufenozide were investigated using larvae from the selection experiments and the results compared with G 6 those for the susceptible larvae. In addition, piperonyl butoxide, an inhibitor (G 0 ) of monooxygenases, when ingested by larvae along with tebufenozide, increased the susceptibility of intoxicated larvae to this ecdysteroid agonist, indicating its oxidative metabolism in Spodoptera larvae.1998 Society of Chemical ( Industry.

“…The leaf dip-bioassay technique (O'Brien et al 1992)have evaluated these insecticides for their efficacy in the field for controlling A. craccivora and the results are reported separately. Reported here are the results of laboratory tests to determine the concentration of these insecticides that is required to kill 50% (LC 50 ) and 90% (LC 90 ) of adults with a modification in the toxicity tests.…”

Field strain of cowpea aphid, Aphis craccivora Koch, was treated by selected neonicotinoid insecticides to evaluate their toxicity and persistence against this pest in Assiut governorate, Egypt. Under faba bean field conditions, acetamiprid, imidacloprid, thiamethoxam and dinotefuran registered significantly high percent reduction of the pest at one, seven, fifteen and 21 post treatment. The residual effects of these insecticides showed that the LT 50 for acetamiprid, imidacloprid, thiamethoxam and dinotefuran were 5.8, 6.2, 6.95 and 4.2 days, respectively. The application of these insecticides on the cowpea aphid under field conditions induced yield increases. The toxicity of these neonicotinide insecticides were tested against field strain of cowpea aphids using leaf-dib bioassay under field and laboratory conditions. The toxicity index showed that thiamethoxam, acetamiprid and imidacloprid have the highest aphicidal activity, with LC 50s 0.60, 0.71 and 1.16 mg/L, respectively, while dinotefuran was the least toxic one with LC 50 23.41 mg/L. Results of this study indicated that neonicotinoid insecticides were highly effective against cowpea aphid under field and laboratory conditions.

“…Gong et al 1) reported that A. gossypii became resistant to organophosphates. Since then numerous studies have been confirmed that A. gossypii became resistant to organophosphates, 6,7) carbamates, 7) and pyrethroid insecticides. 6,[8][9][10][11][12][13] In the early 1980s, highly effective pyrethroid insecticides such as deltamethrin and fenvalerate were imported into China.…”

Resistance of cotton aphid (Aphis gossypii Glover) collected from four leading cotton producing regions and one non-cotton producing region in Shandong Province, China, in 1985China, in , 1999China, in , and 2004 to fenvalerate, omethoate, imidacloprid, acetamiprid, carbosulfan, and endosulfan, was determined on cotton (Gossypium hirsutum L.). Dose-response results indicate that A. gossypii became highly resistant to fenvalerate, and the resistance ratios (RRs) increased from 30-370-fold in 1985 to 370-2150-fold from different regions as compared with the susceptible population (S). A. gossypii also exhibited strong resistance to imidacloprid and acetamiprid with RRs of 17-to 97-fold in 2004. Resistance of A. gossypii to omethoate varied greatly among the five geographical regions, and the RRs ranged from 5-to 80-fold. In contrast, the resistance to carbosulfan did not significantly increase from 1999 to 2004 in all regions. The information from this study would be helpful for management of A. gossypii on cotton in those regions.
