<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Sirex noctilio is a seriously harmful invasive organism for Pinus with strong diffusive and reproductive capacity. To determine the fecundity and its influencing factors, this study investigated the number of eggs carried by S. noctilio females with different size, different nematode infection status and different oviposition frequency. The results showed that egg content of S. notilio was correlated with the width of prothorax, showing a positive exponential correlation. The number of eggs of parasitized females was slightly less than that of non-parasitized females, but the difference between them was not significant. Newly emerged females carry 147.80±10.22 eggs and 50.22±5.46 eggs remained after death. Estimates show that S. notilio oviposited about 30 times before death, and one feamale oviposited 97.58 eggs throughout its life. In observation time, that temperature range 17.49℃from 23.15℃, the oviposition frequency of S. notilio was strongly correlated with temperature. The oviposition frequency increased with temperature, and oviposition frequency decreased with the temperature. At the same time, the fertility formula was improved, and the fertility estimation of S. notilio in China is carried out, according to the survey data. This study defines the reproductive potential of S. notilio with the effect of individual size and nematode infection and the effect of environmental temperature on its reproduction, and provides an important reference for assessing the damage of S. notilio, predicting the spread of S. notilio and developing the prevention and control measures for S. notilio.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Hyphantria cunea Drury is one of the most important forest quarantine pests in China. It has a wide host plant range of more than 600 species in the world, and has caused huge damage to forestry and ecological environment. To clarify the morphological structure of the alimentary tract of H.cunea larvae, can help to explore the feeding habits and digestive physiology of H.cunea larvae. The morphology and ultrastructure of the alimentary tract of H.cunea 6th instar larvae of were observed by optical microscopy, scanning electron microscopy and transmission electron microscopy. The alimentary tract of H.cunea larvae consists of the foregut, midgut and hindgut. The foregut is the longest part of the alimentary tract, which accounts 54.27% of the entire alimentary tract, includes the pharynx, oesophagus, crop and proventriculus. The midgut is relatively short, accounting for only 21.28% of the entire alimentary tract, with a peritrophic membrane inside; the hindgut consists of the pylorus, ileum, colon and rectum. The pylorus consists of the pyloric cone and the pyloric valve. There are 6 malpighian tubes and 2 silk glands. The alimentary tract of H.cunea larvae is similar to most of Lepidopteran alimentary tracts, except that the foregut has a large variation in length. The correlation between the alimentary tract structures of the H.cunea larvae and its self-defense mechanism, feeding habits and hunger tolerance is further discussed.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Dastarcus helophoroides is an important insect natural enemy of Cerambycid wood borers. Releasing adults was one of effective methods to control tree wood borers. To guarantee their activity when releasing the adults, influence of stored temperature and stored period on the adult lifespan and their egg laid numbers were studied. The tested adults were divided into two groups, and one group was feed five days with diet and the other group was not feed. Then the adults of two groups were kept at 4±1℃, 8±1℃,12±1℃ and 16±1℃, respectively, and the mortalities of adults in different treatments were recorded at different times. Afterwards, the egg numbers laid by adults and lifespan of adults were compared among the adults which were stored at the same temperature for different periods. The mortality of adults at 12℃ was the lowest, and the adults in the groups feed with the diet after emerged were not unsuitable for their survive. After stored at 12℃ for the different periods, the egg numbers laid by the adults in all treatments went up firstly and then down with the time past, and there was significant difference among different stored-period treatments (F7,16=83.12, P<0.001). The egg number laid by the adults was the maximum when stored for 60 days at 12℃. The cumulative mortality rates among different stored-periods were also significant different (F7,16=277.82, P<0.001), and the mortality rate was only 38% when stored for 60 days at 12℃. In conclusion, the stored temperature and the stored period had significant influence on the lifespan of adults and the numbers of eggs they laid. The suitable stored temperature would be 12℃ and at this temperature the adults could live longer and had higher egg laid numbers when kept for 60 days.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to clarify the outbreak mechanism and improve the monitoring technical level, we studied the mating behavior and mating ability of  Phenacoccus solenopsis  in room temperature. The results showed that, the males and females could carry on mutiple mating, the mating ability of males was greater than the females. The male mating times were 3-10 times, and the 6 times was the largest proportion, which was 26.7%; The female mating times were 1-4 times, and the 2 times was the largest proportion, which was 40.0%. There was a significant difference of mating duration of  P. solenopsis, that were from 1.8 min to 76.5 min; The average time for each mating was 11.5 min, and less than 10 min were the most, which was account for 68.8%. These studies provided a scientific basis for understanding the mating behavior of  P. solenopsis and studying insect sex pheromone.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Brachyplatys subaeneus (Westwood, 1837) is a natural enemy discovered on the invasive weeds Mikania micrantha in Guangzhou nearly. In this paper, the external morphology of the male and female, as well as the morphology of male genitalia, the morphology and position of clasper, and the structure of aedeagus are detailed. In order to further confirm the morphological identification results, the 16S rDNA and COI gene fragments of its mitochondria were amplified and sequenced. The sequencing results were compared with the sequences in GenBank. The phylogenetic tree was constructed with MEGA5.0 and further confirmed morphological identification results by molecular biology methods. Furthermore, a preliminary comparative analysis was conducted on the potential value of Brachyplatys subaeneus to control Mikania micrantha.]]></description>
