在室内条件下,采用浸虫法测定了10种杀虫剂对柑橘木虱的毒力,结果表明,高效氯氟氰菊酯和溴氰菊酯对柑橘木虱成虫具有较高的毒力,其24 h的 LC50值分别为2.116、3.030 mg · L -1,而吡蚜酮、螺虫乙酯和吡虫啉毒力较差,尤其以吡蚜酮的毒力最差,其24 h的LC50值为2025.489 mg · L -1;采用灌根施药法测定了4种内吸性杀虫剂对柑橘木虱成虫的防效,4种供试验药剂各处理对柑橘木虱成虫的短期效果较差,但10%烯啶虫胺2000倍液、70%吡虫啉14000倍液及7000倍液处理灌根施药后14~28 d对柑橘木虱成虫的防效均保持在87%以上,至药后28 d防效高达97%以上,持效期长。

The toxicity of 10 pesticides and field control efficacy of 4 systemic pesticides to Diaphorina citri were tested with dipping and root pouring respectively for effectively controlling the citrus psylla .The result of indoor determination showed that ,after 24h treatment ,the toxicity of pesticides against Diaphorina citri in LC50 of lambda-cyhalothrin and decamethrin was 2.116 and 3.030 mg · L -1 ,respectively ,which were higher than it of Pymetrozine ,spirotetramat and Imidacloprid .The lowest toxicity was pymetrozine with LC50 2 025.489 mg · L -1 . Though the effect of 4 systemic pesticides controlling citrus psylla in the field was low in short term with root pouring treatment ,the control effects of 10% nitenpyram AS 2 000 times、70% imidacloprid WG 14 000 times and 7 000 times were maintained at 87% during the 14-28 d of the treatment and even reached higher than 97% 28 days after treatments .
