<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Heavy metal contamination in farmland is one of the important environmental problems facing global agriculture. Heavy metals are absorbed by plants, taken in, and accumulated by herbivorous insects, then affected the growth, reproduction, and behavior of natural enemies by bottom-up effects, seriously threatening the efficiency of pest biological control. In this review, the effects of heavy metal transferring along herbivorous insects on natural enemies in farmland ecosystem were systematically summarized, and the direct and indirect effects of heavy metal pollution on pest biological control were expounded. Heavy metal generally leads to negative effects such as delayed growth and development, reduced fecundity, and reduced predation of natural enemies, which directly affects the efficiency of pest biological control. In the meaning time, heavy metal also led to the emergence of poison excitement effect and the enhancement of resistance ability of pests, indirectly increasing the difficulty of pest control. In view of the current research situation, this paper summarizes and looks forward to the deficiency of the research on the influence of heavy metal pollution on natural enemy insects and biological control, and provides reference for the study of natural enemy insects under environmental heavy metal stress and the formulation of pest biological control strategies in heavy metal polluted areas.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Insects, including parasitoid wasps, as a group of poikilotherm, are highly susceptible to high-temperature stress. Parasitoid wasps are the most commonly used natural enemy insects in the field of , in which Trichogramma spp. have been widely used in China for the control of lepidopteran pests in agroforestry. The study of effects of high temperature stress on parasitoid wasps can provide an important theoretical basis for biological control of agricultural and forestry pests in the context of global warming. Here we provide a systematic review on the life activities of parasitoid wasps affected by high temperature stress and the response mechanism of parasitoid wasps. Finally, we also look forward to the problems and challenges of high temperature as an ecological factor in the future large-scale rearing and application of parasitoid wasps, with a view to playing a more important role in biological control in agricultural production.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The mirid bug Nesidiocoris tenuis is an omnivorous predator. In this study, through the comparison of the biological characteristics of sesame-reared population and whitefly prey-plus population, we evaluated the rearing efficacy using sesame and the predatory capabilities of N. tenuis on natural preys. The results showed that the development time of N. tenuis nymphs was prolonged and the hind tibiae length of adults was smaller from sesame-reared population. However, there were no significant differences in female proportion, survival rate, fecundity and the predation abilities of N. tenuis against Bemisia tabaci and Myzus persicae between the two populations. After successive rearing for 10 generations, the innate rate of increase of N. tenuis reared on sesame was 0.2152, close to that of the prey-plus population, which was 0.2398. These findings indicate that sesame can be utilized as the only food nutrition for the artificial rearing of N. tenuis, and this new rearing method provides a reference for the mass production of N. tenuis and the establishment of a field rearing model based on sesame planting.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Eocanthecona furcellata is a crucial natural enemy insect in agricultural and forestry systems. Its alternative prey for mass rearing, Tenebrio molitor pupae, were produced in surplus with a short storage time. To optimize the utilization of this alternative prey, this study investigated the feasibility of using frozen T. molitor pupae at -18℃ as a food source for E. furcellata. The study assessed the nutrient composition after various freezing treatment periods, calculated the nutrient intake of E. furcellata, and analyzed life table parameters in comparison to those fed with live larvae and pupae of T. molitor. Results indicated that freezing T. molitor pupae at -18℃ for more than 30 d significantly reduced the protein and fat content.  E. furcellata population fed on frozen pupae did not show significant differences compared to those fed on live larvae and pupae, except for a longer preadult period. Populations fed on frozen pupae had a higher net reproductive rate R0 (94.60 offspring), intrinsic rate of increase λ (1.1111 d^-1), and finite rate of increase r (0.1053 d^-1) compared to those fed on T. molitor larvae, and slightly lower than those fed on live pupae. In conclusion, T. molitor pupae frozen at -18℃ for 7~14 days maintained their high nutritional value. When fed on frozen-treated pupae, E. furcellata populations exhibited excellent feeding capacity and reproductive adaptability. Therefore, T. molitor pupae frozen under appropriate conditions could be beneficial for rearing E. furcellata. This study provides foundational knowledge for the mass production and standardized rearing of the natural enemy insect E. furcellata.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Light supplementary in greenhouses may affect the application efficiency of natural enemies. In order to explore the spectrum of supplementary light on improving the application efficiency of natural enemies and promote the combination of light supplementary and natural enemy release technology, this study compared the differences in predatory ability of Orius sauteri to Frankliniella occidentalis under red (R), blue (B), red and blue combination (RB) and white (W, control) light treatment under the same light intensity and photoperiod. The results showed that compared with W light, B light significantly reduced the survival of female adult O. sauteri, but R and RB light had no effect on the survival of O. sauteri. R and RB light significantly increased the predatory amount of O. sauteri against F. occidentalis under high prey density. The predatory ability of female adult of O. sauteri to female adult of F. occidentalis under different light spectra fitted the Holling II functional response model, and the searching efficiency decreased with the increase of prey density. Under RB light, O. sauteri had the best predatory ability on F. occidentalis with the theoretical daily maximum prey consumption number of 43.10 individuals/d, and the shortest handling time of 0.0232 d. At the same time, the theoretical daily maximum prey consumed of B light was 42.90 individuals/d, and the handling time was 0.0233 d. The highest instantaneous attack rate of O. sauteri against F. occidentalis was from R light treatment, of 1.0837. In addition, the searching efficiency of O. sauteri on F. occidentalis was highest under RB light, followed by R or B light, and that was the lowest under W light. These results indicate that compared with W light, R, B and RB light can enhance the predatory functional response and searching efficiency of O. sauteri preying on F. occidentalis, but B light can reduce the survival rate of O. sauteri. Therefore, the combination of R or RB light could potentially improve the predation effect of O. sauteri on F. occidentalis. In this study, we evaluated the effects of three commonly used supplementary light spectra on the predation of O. sauteri on F. occidentalis based on predation differences, providing basic data for the application of supplementary light with natural enemies.]]></description>
