  • 摘要：湖北省随州市有松林面积26.7万hm２,占全市林业用地面积70%,占湖北全省的八分之一。过去马尾松毛虫危害十分严重,最大发生面积达到40%以上,每隔3～4年为1个猖獗周期,大发生年份松针几乎全部吃光,成片青山变成了一片焦枯,是全省马尾松毛虫严重危害地区之一。由于只使用化学药剂防治,既破坏了生态环境又得不到有效根治,年年防,年年发生,大发生周期不断缩短,到80年代中期连续几年松毛虫发生面积达到防治标准的都超过6.7万hm２。从80年代开始随州市林业科技人员运用白僵菌防治新技术,结合其他方法进行综合防治,经过试验、示范、推广,到1987年防治面积近7万hm２。他们采用专业队重点区域防治与指导村组农民自己防治相结合,对不同立地类型、不同林龄、不同郁闭度、不同植被的林分采取不同的施放技术,取得了明显成效。到目前为止,连续15年应用白僵菌防治马尾松毛虫累计26.7万hm２,推广应用面积占应防治面积的100%,使马尾松毛虫的发生呈逐年下降趋势,打破了3～4年1个大发生年的周期,累计挽回直接经济损失3000余万元,同时避免了大量使用化学农药对环境产生的污染,确保了全市林分的正常生长,据二类资源调查最新测算,全市活立木蓄积由80年代中期的500万m３增长到现在的1231.5万m３,森林覆盖率由41.5%增长到48.9%,维护了自然生态平衡,林业的社会、生态、经济三大效益十分显著。(随州市林业局徐俊轩)

  • 摘要：摘要：室内生测表明不同浓度芫花乙醇粗提物(YAE)处理叶饲养卫矛尺蠖24h后，导致试虫食量减少，体重下降，且浓度与效果呈正相关。如10%芫花处理组食叶量比CK减少53.78%(重量计)，虫重比原来下降14.81%，而CK体重增加19.51%。β-谷甾醇对试虫食叶量影响虽不明显，但1.0%，0.5%，0.1%处理仍可使试虫体重显著下降。YAE的拒食中浓度为2.76%，β-谷甾醇为0.34%。YAE及β-谷甾醇对4龄斜纹夜蛾的抑制取食及生长的作用均不及卫矛尺蠖显著。%Feeding capacity and growth rate are significantly reduced since the larvae,Abraxas miranda,have taken the leaves treated with Yuan-hua(Daphne genkwa)alcohol extract(YAE)．The higher the concentration,the better is the effect on the insects．For example,the food capacity of larvae eaten leaves contaminated with 10% YAE was reduced by 53.28% as compared with that of control,body weight lost 14.81% of its origin，while weight increased by 19.51% for the control.The effect of β-sitosterol on this insect is much less than that of YAE.The effects of inhibition on feeding and reduction of growth are much less both for YAE and β-sitosterol at any concentrations on the larvae of Prodenia litura.The reason for these are discussed briefly.
  • 摘要：通过对6种苏云金杆菌(Bt)产品在15、20、27℃条件下感染油松毛虫Dendrolimus tabulaeformis试验结果比较，总体结果是Foray48B产品毒力最高，其次是苏州和科瑞森。6种Bt产品平均杀虫效果，20℃比27℃时试虫死亡率下降19.4%，15℃比20℃时试虫死亡率下降32.2%。3种Bt稀释浓度在不同温度条件下均以稀释800倍效果最好，当浓度降低1半时，平均试虫死亡率下降12.3%，当浓度增加1倍时，平均试虫死亡率下降1.6%。在20℃以下时，温度对Bt的杀虫效果影响显著，平均每降低1度，试虫死亡率下降6.4%。低温条件下，增加Bt使用剂量并不能提高杀虫效果。%Compared 6 Bacillus thuringiensis(B.t)products infecting Dendrolimus tabulaeformis （D.t)larvae at 15,20,27℃,the results is as follows:the virulence of B.t Foray48B is the highest among the 6 and the next are Suzhou and Kereisen B.t products. The average mortality of D.t larvae is about 85.0% at 27℃,65.6% at 20℃ and 33.4% at 15℃.The mortality is higher when the titer of B.t products is diluted to 800 times.The average mortality of D.t larvae reduced by 1.6% when the titer doubled.Average mortality of D.t larvae decreased by 12.3％ when the concentration reduced by one-half.

  • 摘要：The female imagoes of the longicorn,Anoplophora glabripennis(Motschulsky)were irradiated with 60 Co T's ray to study its sterility.Results showed that the irradiation had no influence on eating behavior of the female imagoes but notable influence had been produced to its oviposition behavior a clear reduction of its oviposition quantity along with the raise of irradiation dosage.The influences on its life-span and mating behavior were chiefly at 200 Gy's irradiation.It caused the big reduction of the life-span and no mating phenomenon was observed. Thus,it is concluded that the female imagoes of the longicorn also have certain sterility under this kind of irradiation condition.%采用60Co T射线辐照光肩星天牛Anoplophora glabripennis(Motschulsky)雌成虫，研究其不育性。结果表明，辐照对其取食行为无影响；对其产卵行为产生了显著影响，其产卵量随着辐照剂量的提高而明显降低；对其寿命和交尾情况的影响主要表现在200Gy辐照上，致使寿命大辐度降低且未见交尾现象，因而受辐雌成虫也具有一定的不育性。
  • 摘要：Field trapping tests of Cydia strobilella using its newly developed pheromone with 8 formulations were conducted in Heilongjiang Province in 1992 and 1993.The result showed that the formulation 6［(blends of 100μg Z8-12：OH,100μg E8-12：OH and 100μg Z8 E10-12：OH)×60］trapped significantly more moths than other formulations did.But overall catches are not satisfactory considering the relative high attack rate of this pest on Korean spruce cones ,which implies that improvement might be needed on dosages.Trapping test was also attempted in a Dahuri larch seed orchard in 1993 for C．illutana dahuricolana.%1992～1993年在牡丹江柴河林业局红皮云杉母树林和大兴安岭红皮云杉天然林对为害云杉球果的云杉球果小卷蛾Cydia strobilella进行了性外激素诱捕试验。该性外激素于1991年实验合成，共有8种成份组合不同的诱芯，诱捕结果表明第6号诱芯［(100μg Z8-12：OH+100μg E8-12：OH+100μg Z8 E10-12：OH)×60］效果最好。同时也用该性外激素对为害兴安落叶松球果的东北小卷蛾C．illutana dahuricolana进行了诱捕尝试。
