Thewoolly aphis, is one of the major insect pests of the apple in Eastern Shan-tung. Serious damage caused by the attack of the aerial form of this insect in neg-lected orchards, often caused death to the apple trees. According to observations made in Tsingtao, the woolly aphis reproduced anaverage of 8-9 generations, with a maximum of 17 generations per year. Winteris spent mainly by the 1st and the 2nd instar nymphs, hibernating in the woundsand crevices of the apple tree. Overwintering nymphs nd apterous agamic femaleswere also found at the base of the trunk just below soil level, and on suckers thathad been allowed to grow around the tree, but the damage caused by the root formof this insect is negligible. By the end of April to early May (average temperature 11.0-14.3℃) newly-born nymphy were seen to crawl to the base of the young growing shoots. Thepeak of migration being in June and the early part of July, where an average ofonly 8.2 days is needed to complete a cycle. Each female may then give forth toan average of 94.2 nymphs parthenogenetically. Two gererations of winged agamic females were recorded during the wholelife history. The summer form, though not often seen, occured from May 20 to June23, these gave birth to apterous agamic females and sexuales. Towards the latterpart of August, a brood of fall winged migrants are developed. Their number in-creased as the colonies grow, reaching an average of 23.1-46.4% of winged indivi-duals per colony by September 18 to October 18. The fall migrants gave birth onlyto wingless and mouthless true males and females. After pairing, only a singlefertilized egg was laid by the female. Due to the high mortality of these sexuales,no eggs as yet was found overwintering on the apple tree. Eggs obtained in labora- tory conditions and hundreds of adult sexuales transplanted in October to previous-ly sterlized wounds on the branches of the apple tree, also failed to hatch in thefollowing year, though further works are still being needed to ascertain this fact. Early instar nymphs were also found to infest the calyx of the fruit, thoughnone of them could live up to the adult stage. According to a preliminary test on20 infested apples stored under room temperature from September to October, nonymphs were found to be alive in the calyx after 50 days storage. Studies madeon the time of calyx infestation are in accordance with those of migration. The natural enemies of the woolly aphis are in the order of their importance:a minute chalcid parasite (Aphelinus mali Hald.), the larva of a Chrysopa sp., ladybird beetles and a syrphus maggot. These played an important part in the sup-pressing of this pest in some months of the year. Based on these facts and on the lifehistory of the woolly aphis, an effective spray program has been devised in the controlof Eriosoma. These include a resin wash solution to be diluted with 20 parts ofwater plus 0.02%γ wettable BHC or 5%-6% tar distillate, to be applied in the dor-mant stage; followed by two successive sprays of 0.02-γ-0.03%γ BHC during theearly period of migration, about May 15 and June 10. At the above concentrationand time of usage, BHC proved to have no deleterious effect on the apple.

本文是介绍有机磷农药乐果及其主要代谢物氧乐果在茶树上的残留降解动态。根据实验结果,在自然条件下,乐果在茶树芽梢上的降解速度中等。喷施800倍和1600倍药液后,芽梢中的乐果含量10天后可降至<0.5ppm和<0.05ppm。干茶中的乐果含量5天后降至<1.0ppm以至0.7ppm,9天后降至<0.1ppm。在喷施乐果的茶树芽梢上可检出其氧化物一氧乐果。喷药后3—5天达最高值,以后渐降,6—9天后即降至品质有影响,故建议:喷施2000倍液安全间隔期为7天;喷施1000倍液安全间隔期为10天。
