Abstract:

Phenacoccus solenopsis Tinsley poses a significant threat as an invasive pest in our region with severe implications for cotton, eggplant, and other plant species. Its formidable challenge for prevention and management stems from its large spawning amount, strong reproduction ability and fast development rate, leading to extensive crop damage. To address timely and effective emergency response strategies against P. solenopsis Tinsley, we compared and analyzed the prevention and control effects of 5 chemical agents, including 24% spirochaete·pyriproxyfen, 33% spiroxamine, 28% pukechu, 40% fluoxetine·spirotrifonate and 22% spiroworm·Thiacloprid on this pest. The results showed that 22% Spiroworm·Thiacloprid had the best control effect on P. solenopsis Tinsley, and the control effect of 1∶1 000 diluent was up to 90.0% after 2 days.
