Transmission of Bt Toxin to the Predator Propylaea japonica (Coleoptera: Coccinellidae) Through Its Aphid Prey Feeding on Transgenic Bt Cotton
TL;DR: It is indicated that Bt toxin expressed in transgenic cotton cultivars can be transmitted to a higher trophic level through a nontarget pest insect and may alter the biology and behavior of a predatory ladybird.
Journal ArticleDOI
Real-time PCR quantification of Bemisia tabaci (Homoptera: Aleyrodidae) B-biotype remains in predator guts
TL;DR: Results suggest that TaqMan real-time PCR technology may provide a rapid and sensitive method for quantifying B. tabaci B-biotype remains in predator guts and will be invaluable in assessing the food web relationship between prey and arthropod predators.
Journal ArticleDOI
Outbreak of the South American tomato leafminer, Tuta absoluta, in the Chinese mainland: geographic and potential host range expansion
Gui-fen Zhang,Xiao-qing Xian,Zhang Yibo,Wan-Xue Liu,Hui Liu,Xiao-dong Feng,Ma Deying,Yu-sheng Wang,You-hua Gao,Rong Zhang,Qing-hong Li,Fang-Hao Wan,Fu Wenjun,Jun Wang,Meng Kuang,Wen-jia Yang,Xi Rao,Ying Gao,Ai-mei Dai +18 more
TL;DR: Wang et al. as mentioned in this paper investigated the impact of T. absoluta on China's tomato production industry and determined its geographic distribution and host range, intensive surveys and routine monitoring were conducted across the Chinese mainland between 2018 and 2019, and calculated the population colonization coefficient (PCC; ratio of colonized sites and prefectures) and population occurrence index (POI); ratio of infested host species and PCCs.
Journal ArticleDOI
Asymmetric consequences of host plant occupation on the competition between the whiteflies Bemisia tabaci cryptic species MEAM1 and Trialeurodes vaporariorum (Hemiptera: Aleyrodidae).
TL;DR: The interspecific interactions between B. tabaci MEAM1 and T. vaporariorum were asymmetric, with B.tabaci MEam1 being the superior competitor, which could partially explain the rapid spread of B. tabsia tabaci MeAM1 in China.
Journal ArticleDOI
Climate Change Increases the Expansion Risk of Helicoverpa zea in China According to Potential Geographical Distribution Estimation
TL;DR: According to bioclimatic conditions, H. zea has a high capacity for colonization by introduced individuals in China and should exchange information to strengthen plant quarantine and pest monitoring, thus enhancing target management.
