本文利用高效液相色谱(HPLC)对银盾革蜱饥饿、吸血和饱血后若虫整体水平20-羟基蜕皮酮含量变化规律进行了研究.结果表示20-羟基蜕皮酮存在于若虫整个发育期,其含量变化具有两个峰.第一个峰小,出现在吸血期(吸血后5天),含量为2.34ng/只,该峰出现后,若虫快速饱血并从宿主体落下;第二个峰大,出现在蜕化期(饱血后8天),含量为16.17ng/只,此峰可能与上表皮沉积有关.从饱血后第6天至饱血后第8天,20-羟基蜕皮酮含量迅速增加,皮层溶离发生在饱血后7天左右.

Morphology and morphometry of six biotypes （B, Q, Cv, ZHJ-1, ZHJ-2 and ZHJ-3） of Bemisia tabaci （Gennadius） from China on cotton plants were studied by using microscopes. nymphal body sizes and characters were measured and observed, especially on the 4th instar （pupal case）, including the vasiform orifice, operculum, lingula, length and thickness of anterior and posterior wax margins, width of thoracic tracheal combs. Adult characters of both sexes were investigated including the body size, compound eyes, antennal segments, vasiform orifice, hind tarsi and genitals. The results indicated that differences of some morphological characters or morphometrics were significant among the six biotypes of B. tabaci in China：（1） Pupal sizes of the exotic biotypes （B and Q） were significantly larger than the indigenous biotypes with the following order as B〉Q〉ZHJ-I〉Cv〉ZHJ-3〉ZHJ-2; （2） for both male and female adults, sizes of all characters investigated in the invading biotypes （B and Q）, especially B, were much larger than those of the indigenous ones.

A new species of ice crawlers from Burmese amber(Insecta:Grylloblattodea)

Zoological Systematics 2016年第3期41卷 327-331页

作者： Weiwei Zhang Mingxia Guo Xingke Yang Ming Bai Key Laboratory of Zoological Systematics and Evolution Institute of Zoology Chinese Academy of Sciences Beoing 100101 China Three Gorges Entomological Museum Chongqing 400015 China

Modem grylloblattids are one of the least diverse insect orders. The single extant family is contrasted with 46 families described from the fossil records, which extend to the Late Carboniferous. The most ancient grylloblattid nymphs are known from the Lower Permian. Till now, there is no report on grylloblattid from Burmese amber, which is a very old amber locality. Herein, we describe Sylvalitoralis cheni Zhang, Bai ＆ Yang, sp. nov. from Grylloblattina based on a nymph specimen from the mid-Cretaceous Myanmar （Burmese） amber.

关键词： Grylloblattodea nymph Burmese amber Sylvalitoralis cheni new species.

Biological Cycle of Bug Pseudotheraptus devastans Distant (Heteroptera: Coreidae), the Coconut Pest in Côte d’Ivoire

Advances in Entomology 2016年第1期4卷 19-24页

Pseudotheraptus devastans Distant (Heteroptera: Coreidae), is an important coconut pest in C?te d’Ivoire. The stings from nymph and adult cause not only the falling of immature nuts, but also their deformation. This triggers losses of production in the order can reach 80%. Little information is available about this pest. Those existing are limited to its ecology and damages caused in host-plants. The present investigation is aimed to study the life cycle of this pest. The experiment was carried out in a coconut field of the Marc Delorme Coconut Research Station (MDCRS). On these coconut palms, bunches between 3 and 4 months of age, enclosed in cage were used. Development duration from an egg to adult emergence averaged 28.26 days. The average incubation period was on average 6.63 days and fertility rate of eggs was 98.01%. nymphal development period was 21.63 days. The sex-ratio is in favour of females which live 112.6 ± 13.45 days. These females laid on average 198.85 ± 36.05 eggs. The males lived on average 131.3 ± 17.7 days. The knowledge of these different parameters could allow the development of a control method based on the breaking of life cycle of this pest.
