核桃举肢蛾是核桃主要害虫,以幼虫蛀食核桃青果,使果变黑而早落,直接影响当年产量。1977年,我们在洛南县石门公社安沟、沙岭、下铺3个大队调查,61株结果树中,受害树就有49株,受害株率达80.3%,受害果率达39.9%。这3个大队当年因举肢蛾为害减产1/3,少收核桃4000多斤。目前,我国核桃产区,大都沿用6%可湿性六六六和25%滴滴涕乳剂防治此虫,但由于这两种药对人畜有累积性毒害,国家已列为淘汰药剂,货源越来越少。所以探索防治
Walnut Ligustrum moth is the main pest of walnut, walnut fruit eating larvae, darkening fruit and early fall, a direct impact on the current production. In 1977, we surveyed 3 brigades of An ditch, Shaling and Bunkow in Shimen commune of Luonan county. Of the 61 trees, there were 49 trees damaged, the rate of affected plants was 80.3% and the rate of suffering fruit was 39.9%. The three brigade that year caused by the exhumation of moth cut production 1/3, less than 4,000 kilos walnuts. At present, most of the walnut-producing areas in our country use 6% wettable 666 and 25% DDT emulsions to prevent and control this pest. However, due to the cumulative toxicity of these two drugs to humans and animals, the country has been phased out pharming agents with fewer and fewer supply sources . So explore prevention and treatment
