桃实蝇(Bactrocera zonata)严重危害桃、番石榴、番荔枝等经济作物,被我国列为进境植物检疫性有害生物。为明确桃实蝇各虫态的重要形态鉴定特征,并将DNA条形码技术应用于桃实蝇的鉴定,本研究针对采自于印度旁遮普邦的桃实蝇卵、幼虫、蛹和成虫样品进行了形态观察和分子鉴定。结果表明:桃实蝇成虫整体呈红褐色,头部具一对卵圆形黑色颜面斑。翅除前缘带和臀条外几乎透明,r_(2+3)室端部具"痣状"小褐斑,延伸至r_(4+5)室端部。实蝇成虫及蛹样品的COI条形码序列与GenBank中收录的桃实蝇序列相似度在99.24%～100%之间;基于COI条形码构建的系统发育树显示本研究所有样品和桃实蝇聚在一个分支上。本研究表明DNA条形码技术可有效应用于桃实蝇的准确鉴定。 相似文献

The developmental biology of Mallada desjardinsi (Navas) and Chrysoperla congrua (Walker) on the American bollworm, Helicoverpa armigera and the cotton aphid, Aphis gossypii was studied in the laboratory at 28–32°C. Total larva! periods of M. desjardinsi and C. congrua on H. armigera eggs were 14.4 and 14.8 days respectively. However, when reared on A. gossypii larval periods of M. desjardinsi and C. congrua were 14.9 and 13.5 days respectively. When reared on H. armigera 52.9% and 25% respectively of third instars of M. desjardinsis and C. congrua sp. died before pupation. However, when reared on A. gossypii 82.6% and 46.9% respectively of third instars of M. desjardinsi and C. congrua died before pupation. Thus, H. armigera eggs and A. gossypii nymphs were both adequate but not optimal diets for chrysopid larval development. The number of prey consumed by M. desjardinsi and C. congrua increased with instar. Total larval consumption of H. armigera by M. desjardinsi and C. congrua was determined to be 135.5 and 169.8 eggs respectively. However, total larval consumption of A. gossypii by M. desjardinsi and C. congrua was found to be 189.0 and 171.8 nymphs respectively. Because of its longer larval period, and higher consumption of A. gossypii, M. desjardinsi would be better suited for use against A. gossypii than C. congrua. In contrast, C. congrua whose consumption of H. armigera was higher than that of M. desjardinsi although their larval periods were similar, would appear promising for control of H. armigera. 相似文献

为明确胡瓜新小绥螨Neoseiulus cucumeris Oudermans对烟粉虱Bemisia tabaci Gennadius的控害潜能,在（26±1）℃、相对湿度65%±5%、光周期16L：8D条件下,研究了各螨态胡瓜新小绥螨对不同发育阶段烟粉虱的捕食作用。结果表明,胡瓜新小绥螨幼螨期较短,不取食烟粉虱,其他不同螨态的胡瓜新小绥螨可捕食除4龄若虫和成虫以外的其他各虫态的烟粉虱,捕食功能反应符合HollingⅡ型;胡瓜新小绥螨雌成螨对烟粉虱卵的日捕食量最大（8.5粒/雌）,对烟粉虱3龄若虫的日捕食量最小（2.1头/雌）;雌成螨对烟粉虱卵具有较高的瞬间攻击率（0.038）和寻找效应（0.025）。研究表明,胡瓜新小绥螨对烟粉虱卵及低龄若虫的捕食能力较强,是烟粉虱发生初期的有效天敌。 相似文献

The rates at which (E)- and (Z)-mevinphos are hydrolysed in aqueous solutions in the pH range 8.7–11.5, and in the temperature range 30–50°C, have been measured. The overall activation parameters have been calculated, and equations to allow calculation of the rates in any basic conditions are given. The complicated routes by which (E)- and (Z)-mevinphos are hydrolysed to simple molecules have been deduced. The rates for the individual steps in each route have been either measured experimentally, or have been calculated through analogue simulation of all the reactions, by matching the calculated to the observed ultraviolet spectral changes during hydrolysis. It is proposed that (Z)-2-carboxyl-1-methylvinyl dimethyl phosphate is not observed as a hydrolysis product of (Z)-mevinphos because it decomposes by an extremely fast intramolecular reaction. The reasons for the greater lability of (E)-mevinphos are also discussed. 相似文献

Tuta absoluta (Meyrick) (Lepidoptera,Gelechiidae) in the Republic of Srpska (Bosnia and Herzegovina)
Pheromone traps were placed in the market place in Banja Luka, and in greenhouses and open field tomato crops, on 13 September 2010 to determine the presence of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in Banja Luka region. Based on examination of traps, the presence of T. absoluta was confirmed for the first time in the Republic of Srpska. Only mines of Liriomyza species were found by examining leaves under a stereomicroscope. In 2011, pheromone traps were placed in greenhouses at several locations (Banja Luka, Prijedor, Novi Grad, Kozarska Dubica, Ljubinje and Trebinje) at the beginning of June, and in open fields in Bijeljina and Trebinje at the beginning of September. Examination of the traps was carried out at intervals of 15 days. A sample of 100 leaves, taken from 20 randomly selected plants, was examined in order to evaluate the intensity of the attack. The first adults were caught in greenhouses in Ljubinje and Trebinje on 18 June 2011; in open field crops in Bijeljina on 9 September 2011 and in Banja Luka on 5 October 2011. Adults were not captured in Prijedor, Novi Grad or Kozarska Dubica, and no mined leaves were observed. The intensity of attack was evaluated on the basis of active infestation (percentage of leaves with active mines compared with all mined leaves). The strongest intensity of active infestation was recorded in the open field crops in Trebinje, where 19% of leaves with active mines were found. 相似文献

Summary During four years yellow rust was observed on cocksfoot. Telia did not occur in the field, but in the glasshouse they appeared. In the field only the minority of cocksfoot-plants was susceptible. Hibernation in the field was not observed, the yellow rust could only be stated in summer after May.In several inoculation-experiments it was found, that this origin of yellow rust was not pathogenic for several varieties of wheat, barley and rye. The type of infection was always i and 00-0.According to the experiments of Straib, this type of yellow rust might be identical to physiologie race 36. Otherwise it is a new physiologie race, till now not numbered. 相似文献
