China: Would micro-ecology be damaged by a plastic film that kills a harmful soil insect?

Tridge summary

A team of Chinese researchers has found a way to control the soil insect Bradysia cellarum, which is damaging Chinese chive crops, using soil solarization and a light blue anti-dropping film. Soil solarization is a pesticide-free and non-destructive method that increases the abundance of beneficial microorganisms in the soil. The study found that the film effectively controlled the insect while minimally impacting the growth of Chinese chive and the soil's microbial diversity. The research suggests that soil solarization could be a viable solution for controlling B. cellarum in Chinese chive-growing regions.

Chinese chive (Allium tuberosum) is a perennial herbaceous vegetable with medicinal qualities. Unfortunately, Chinese chive crops are severely damaged by the soil insect Bradysia cellarum. B. cellarum are mainly found in the surface soil to a depth of 5 cm. Department of Plant Protection, Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences Investigator Youjun Zhang and his team showed that thermal treatment of B. cellarum adults, eggs, larvae, and pupae at 40 °C for 3 hours produced mortalities of 100%, 100%, 100% and 81%, respectively, and the fecundity of B. cellarum significantly decreased with increasing temperature and exposure time, completely inhibiting egg-laying at 37°C for 2 hours. These data suggested that B. cellarum is quite sensitive to elevated temperatures. As long as soil temperature to a depth of 5 cm is increased and remains over 40°C for 4 hours, the mortality rate of B. cellarum will be 100%. Therefore, the team has been studying how ...
