Plutella xylostella is small in size, has strong ecological adaptability, and has a short life cycle (at temperatures of 28°C to 30°C, it takes 10 days to complete the first generation). It is difficult to control the production of diamondback moths. With the large-scale use of chemical pesticides in recent years, natural enemies have been largely killed. Diamondback moth has produced over 50 insecticides including organochlorine, organophosphorus, carbamate and pyrethroid insect growth regulators. Different degrees of resistance.
You can use the plutinozoites' phototaxis habits to trap adults with black light or other light sources at night from 7 to 11 o'clock. The main trapping is from April to May, or other light sources are used to trap the adults.
Plutella xylostella, Plutella xylostella, and Plutella xylostella have the most obvious control of Plutella xylostella, and they can release natural enemies of Plutella xylostella and control them.
Can use Bacillus thuringiensis Pharmacy, 8000 international units per milliliter / ml, diluted 500 to 1000 times spray. The application dose should not be too high or too low, with emphasis on the control of young larvae, especially 1-2 larvae. Avoid spraying at high temperatures, preferably in sunny afternoons or cloudy days, and do not apply at temperatures below 15°C. Focus on the back of the leaf.
From the hatching of the diamondback moth eggs to the second instar larvae, use 1% emamectin cream, 15 to 25 ml/mu, spray 50 kg of water, or use a 5% fipronil suspension, 20 ~ 40 ml/mu, watered 50 kg spray, can also use 10% of chlorfenapyr suspension, 35 ~ 50 ml / mu, watered 50 kg spray.
