The white peach scale Pseudaulacaspis pentagona Targioni during the middle of first instar nymphs could be controlled with dilution (1:1000-1500, W.P.. water) of 25% buprofezin W. P. spraying one time in the peach garden. Its effect for controlling its instar nymphs reached 92.2 % -96.3% and persisted for three weeks. However toxic effect was slower than that of conventional insecticides.

在桃树桑白蚧一龄若蚧盛发期,用25%扑虱灵可湿性粉剂1000~1500倍稀释液、防治1次,就可有效地控制其为害,是抗治该蚧的理想药剂。对一龄若蚧防治效果为92.2%~96.3%,持效期长达3周以上,但毒杀速度较慢。

Nysius inconspicus Distant injures Ameranthaceae, as well as Graminaceae and Chrysanthemum.It developes 4-5 generations a year in Jiaxing, Zhejiang. In hot summerl it has long periodsof adult stage, short periods of nymph and egg stage, piling up it's generations, and injures plantskeavily. As in cool autumn, it has long periods of nymph and egg stage, and the injury on plants isnot seriously. Controls were carried out effectively as using agricultural methods combined with sprcading of insecticides.

黄色小长蝽除危害苋科外,还危害菊科、禾本科等作物。该虫在嘉兴1年发生4~5代。夏季高温,成虫寿命长,若虫、卵历期短,世代重叠,为害重;秋季转凉,若虫、卵历期长,为害轻。防治上采用农业与药剂防治相结合,效果良好。

n omethoate-resistant strain of carmine spider mite(Tetranvchus cinnabarinus Boisdu-val)was obtained by laboratory selection of a colony collected from Henan cotton field after16 selections with omethoate in a concentration ranging from 66.67 to 133.33(μl/L)during16 generations and got a resistance to this insecticide increased from 8. 33 folds(before selec-tion)to about 36.93 folds。This was compared with a susceptible population collected fromGushi county in Henan province to ensure a homogeneous colony...

n omethoate-resistant strain of carmine spider mite(Tetranvchus cinnabarinus Boisdu-val)was obtained by laboratory selection of a colony collected from Henan cotton field after16 selections with omethoate in a concentration ranging from 66.67 to 133.33(μl/L)during16 generations and got a resistance to this insecticide increased from 8. 33 folds(before selec-tion)to about 36.93 folds。This was compared with a susceptible population collected fromGushi county in Henan province to ensure a homogeneous colony for the mode inheritancetests。LC-P lines of the reciprocal crosses(RS,SR)were closed to those of R strain,and thedegree of dominance(D)was estimated to be 0.5679 and 0.5659, respectively,suggestingthat there were no maternal effects and omethoate resistance in this mite was incompletelydominant.The results obtained from the backcross of SR_♀×S_♂ indicated that omethoate re-sistance was inherited as a single gene。

对采自棉田的朱砂叶螨(Tetranychascinnabarinus)种群使用氧化乐果选择压(66.67-133.33μl/l)16次筛选后,抗氧化乐果由8.33倍上升到36.93倍。利用此抗性品系(R)和来自河南省固始县的敏感品系(S)杂交和回交,研究了朱砂叶螨抗氧化乐果的遗传方式。正交和反交(SR和RS)F_1代的LC-P线介于S与R之间偏向R方,显性系数D_(SR)和D_(RS)分别为0.5679和0.5659,表明抗性是由不完全显性基因控制。对F_1杂合子与亲本的回交(SR_♀×S_♂)F_2代测定表明抗性由单个基因控制。
