| 摘 要： | 湘黄卷蛾Archips strojny Razowski是2015年杭州茶园发现的一种茶树新害虫。为了准确识别该虫,明确其生物学特性,通过室内观察和田间调查,对湘黄卷蛾不同发育阶段的形态特征和生物学特性进行了初步观测。结果表明,湘黄卷蛾卵粒覆瓦状排列成卵块,卵块多为条形或椭圆形;幼虫共有5龄,1~5龄的平均头宽0.25~1.61mm;成虫停息时呈钟形,雌雄蛾的前翅斑纹有明显差别。在4-6月自然温度条件下,卵期、幼虫期和蛹期分别为7.7、29.6、8.8d,成虫产卵前期平均为4.3d,产卵可持续2.6d,雌雄蛾平均寿命分别为8.5d和9.1d;成虫羽化高峰为10:00-13:00,每雌产卵量平均353粒。

| Abstract: | It is reported for the first time that Archips strojny Razowski,a Tortricidae insect pest,occurred in tea garden of Hangzhou,Zhejiang Province.To identify the species and clear out its occurrence regularity,morphological and biological characteristics of the pest were systematically observed.The results showed that the eggs were imbricated together as bar-type or elliptic egg mass mostly.The larvae experienced 5 instars and the mean head width of 1-5 instar was ranged from 0.25 mm to 1.61 mm.The adults looked like a bell when settled on the tea leaves and there were obvious differences in stripes on forewing between male and female moths.Under natural condition in April to June,the developmental duration of egg,larva,pupa and adult was 7.7 d,29.6 d,8.8 d and 8.5 d (♀) / 9.1 d (♂),respectively,and the oviposition period of adults was 2.6 d.Diurnal peak of emergence was 10:00-13:00.The average fecundity was 353 eggs per female. |
