Article
Full-text available
The integrated use of plant-derived volatile attractants and synthetic insecticides in attract-and-kill programs is a useful tool for integrated pest management programs reducing pesticide input. Efficient alternative insecticides are critically needed to replace methomyl, which has been banned on cruciferous vegetables in China because it is also...

Background: The integrated use of plant-derived volatile attractants and synthetic insecticides in attract-and-kill programs could provide a basis for selective and environmentally-acceptable pest management strategies with applicability for use against multiple pests. Ryanoid insecticide, chlorantraniliprole, has been found to present a potential...

Methods to trace source habitats and movement of parasitic natural enemies in agroecosystems are limited. This study demonstrates that stable carbon isotope analysis offers a valuable new method for revealing the movement of Microplitis mediator (Haliday) (Hymenoptera: Braconidae), a larval endoparasitoid of Helicoverpa armigera Hübner (Lepidoptera...

Resource-continuity over spatial and temporal scales plays a central role in the population abundance of polyphagous pests in an agricultural landscape. Shifts in the agricultural land use in a region may alter the configuration of key resource habitats, resulting in drastic changes in pest abundance. Apolygus lucorum (Meyer-Dür) (Hemiptera: Mirida...

Abstract While the host plant use of insect herbivores is important for understanding their interactions and coevolution, field evidence of these preferences is limited for generalist species. Molecular diet analysis provides an effective option for gaining such information, but data from field‐sampled individuals are often greatly affected by the...
Article
Ladybeetles are promising contributors of biological control services in agricultural landscapes, potentially providing significant economic gains in agricultural production. In northern China, ladybeetles are the most common predators in the annual double-crop rotation system, where the dominant crops are wheat in the spring and maize and cotton i...

Aphids are major pests of cotton crops in the Xinjiang Uygur Autonomous Region in China, and parasitoids are considered as important natural enemies in regulating aphid populations. However, information on aphid parasitoids in the Xinjiang cotton fields is limited, which hinders the study of aphid-parasitoid interactions and the application of cons...
Article

BACKGROUND Although the abundance of insect natural enemies in crop fields may be influenced by the surrounding landscape pattern and local field management, especially by insecticide use at the local scale, few studies have examined these factors simultaneously. In this study, we investigated the effects of landscape context and insecticide use in...
Article
Agricultural landscape composition is reported to have effects on the occurrence of natural enemies in fields, but the responses of herbivorous pests to landscape features have rarely been studied. Our previous landscape-level study in northern China found that natural enemies had no significant effects on the population growth of wheat aphids at t...

The improvement of biocontrol services provided by natural enemies is important for realizing sustainable agriculture. While it has been well demonstrated that landscape context affects the occurrence of natural enemies in agricultural ecosystems, the response of natural enemies and their ability to suppress pest population growth over time has rar...
