Can insecticide mixtures be considered to surmount neonicotinoid resistance in Bemisia tabaci?

چکیده
Cotton whitefly, Bemisia tabaci is an important polyphagous pest worldwide. It exposed to various chemical insecticides throughout the year, resulting in rapid development of insecticide resistance. Mixtures with distinct modes action could enhance toxicity chemicals more effectively than sequences or rotations resistant populations. Bioassays were conducted study efficacy mixtures neonicotinoid and ketoenol at different ratios against a laboratory susceptible (Lab-WB) (TMX-SEL) strain B. Asia I. The results showed that imidacloprid, acetamiprid, thiamethoxam dinotefuran spiromesifen 1:1, 1:10 1:20 spirotetramat 1:1 ratio significantly increased (p < 0.05) neonicotinoids TMX-SEL strain. combination indices each tested + ketoenols acetamiprid spiromesifen, imidacloprid for below 1, suggesting synergistic interactions. inhibitors PBO DEF largely overcame resistance neonicotinoids, while none synergists restored susceptibility ketoenols. Increased activities P450 monooxygenase esterase observed elevated 2.76 1.32-fold, respectively. be used restore tabaci.

The resistance levels to alpha-cypermethrin, bifenthrin, pirimiphos-methyl, endosulfan and imidacloprid were determined in Bemisia tabaci (Gennadius) from Crete. Five B tabaci populations collected from greenhouse and outdoor crops were bioassayed and compared with a reference susceptible strain. Bemisia tabaci collected in a floriculture greenhouse exhibited the highest resistance against all ...

The whitefly Bemisia tabaci (Gennadius) is an important agricultural insect pest worldwide. The B and Q biotypes are the two most predominant and devastating biotypes prevalent across China. However, there are few studies regarding the occurrence of the Q biotype in Fujian Province, China, where high insecticide resistance has been reported in the B biotype. Differences in some biological chara...

Bemisia tabaci (Gennadius) biotype B is a highly prolific and polyphagous whitefly that established in much of North America during the 1980s. Neonicotinoid insecticides have been fundamental in regaining control over outbreak populations of B. tabaci, but resistance threatens their sustainability. Susceptibility of B. tabaci in the southwestern United States to four neonicotinoid insecticides ...
