Abstract BACKGROUND In 2017 Tuta absoluta was identified as an invasive species in China. Due to its rapid geographic expansion and the severe crop damage it causes, T. poses a serious threat China's tomato production industry. To determine distribution host range, intensive surveys routine monitoring were conducted across Chinese mainland between 2018 2019. The population colonization coefficient (PCC; ratio of colonized sites prefectures) occurrence index (POI; infested PCCs) calculated. RESULTS northwestern China, populations established Xinjiang exhibited medium PCC value (~0.03). southwestern Yunnan five neighboring provinces high (~0.50 Guizhou), or low (<0.02 Guangxi, Sichuan, Hunan, Chongqing) values. mainland, infestations four plant (tomato, eggplant, potato, lantern) two wild (black nightshade Dutch eggplant) identified; tomatoes every province. lantern eggplant are potentially novel hosts. Yunnan, Guizhou, experienced most (POI). observed significantly decreased with increased distance from first discovery site farthest county province increased. CONCLUSION well‐established could spread other regions present study helps inform establishment better pest management guidelines strategies China tomato‐producing worldwide. © 2021 Society Chemical Industry.

Comparing, evaluating and combining statistical species distribution models and CLIMEX to forecast the distributions of emerging crop pests

Forecasting the spread of emerging pests is widely requested by pest management agencies in order to prioritise and target efforts. Two used approaches are statistical Species Distribution Models (SDMs) CLIMEX, which uses ecophysiological parameters. Each have strengths weaknesses. SDMs can incorporate almost any environmental condition their accuracy be formally evaluated inform managers. However, affected data availability limited for pests, usually predict year-round distributions, not seasonal outbreaks. CLIMEX expert knowledge predicts methods formal evaluation rarely applied. We argue that both informative complementary, but we need tools integrate evaluate accuracy. Here develop such an approach, test it forecasting potential global range tomato Tuta absoluta.The previously developed new were comparable on average, best SDM techniques substantially outperformed CLIMEX. The ensembled approach changes expectations T. absoluta's spread. pest's tolerances Africa, Arabian Peninsula, Central Asia Australia will larger than previous estimates.We recommend considered one a suite thus formally. should compared if possible. provide code do so when employing biomod techniques. © 2021 Authors.

Does the dose make the poison? Neurotoxic insecticides impair predator orientation and reproduction even at low concentrations

Pest Management Science, Journal Year: 2022, Volume and Issue: 78(4), P. 1698 - 1706

Published: Jan. 7, 2022

Pesticides can be noxious to non-target beneficial arthropods and their negative effects have been recently recognized even at low doses. The predator Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) plays an important role in controlling insect pests solanaceous crops, but its concurrent herbivory often poses relevant concerns for tomato production. Although insecticide side on N. previously studied, little is known the potential implications of neurotoxic chemicals concentrations. We assessed baseline toxicity three insecticides (lambda-cyhalothrin, spinosad chlorpyrifos) by topical contact exposure. behavioral reproduction capacity was then investigated upon exposure estimated low-lethal concentrations (LC
