摘要
为明确鸡粪沼液"新壮态"对韭菜迟眼蕈蚊的防控效果,于室内测定了其对韭菜迟眼蕈蚊卵和不同龄期幼虫的毒力,研究了其对韭菜迟眼蕈蚊雌成虫产卵和幼虫取食的驱避效果,并进行了田间药效试验。结果表明,"新壮态"0倍稀释液对韭菜迟眼蕈蚊卵有杀灭作用,死亡率达54.76%;对2~4龄幼虫均无直接毒杀作用;对雌成虫产卵和幼虫取食均有明显的驱避活性,对雌成虫产卵驱避率为74.75%,处理5 min后对幼虫的选择性和非选择性驱避率分别为78.62%和45.60%。田间药效试验表明,鸡粪沼液"新壮态"对韭菜迟眼蕈蚊有一定的控制作用,并明显增加韭菜产量。
To study the control efficacy of biogas slurry of chicken manure（New Status） on Chinese chive gnat Bradysia odoriphaga, the toxicity of New Status against eggs, larvae of B. odoriphaga were tested in laboratory by the dripping ration liquid methods and the stomach-contact combination toxicity methods, respectively. Besides, repellent effects of New Status against larvae and female adults of B. odoriphaga were evaluated in laboratory and the control efficacy against B. odoriphaga were also determined in the field. Results showed that New Status 0 times dilution had ovicidal activity against B. odoriphaga, and the mortality of eggs reached 54.76%, however, it showed no negative effects on 2nd, 3rd and 4th instar larvae. New Status showed obvious repellent activity to adult oviposition and larval feeding of B. odoriphaga. The oviposition repellent rate was 74.75%, and the repellent rates of larvae were 78.62% and 45.60% after 5 minutes in larvae choice and non-choice tests, respectively. Field trials indicated that New Status displayed certain controlling efficacy on B. odoriphaga, and it may increase Chinese chives yields.
