The South American tomato pinworm Tuta absoluta (Meyrick) has aggressively invaded the African continent. Since its first detection in North Africa Morocco and Tunisia 2008, it successfully entire southern, eastern western Africa, where been on offensive, causing significant damage to Solanaceous food crops. While control of this prolific invader is primarily based conventional synthetic pesticides, form consistently losing societal approval owing (1) pesticide resistance development consequential loss field efficacy; (2) growing public health concerns; (3) environmental contamination biological diversity associated ecological services; (4) unsustainable costs, particularly for resource-poor farmers. As such, more ecologically sound pest management strategies, e.g., use natural substances (NSs), may offer a sustainable approach tackling offensive. A systematic literature search through digital libraries online databases (JSTOR, PubMed, Web Science, SCOPUS Google Scholar) was conducted using predetermined keywords T. absoluta, pinworm. We explain invasion citing mechanisms facilitating exploring potential diverse agents, low-risk substances. Specifically, we explore how botanicals, entomopathogens, semiochemicals, predators, parasitoids, host plant resistance, sterile insect technique others have spatially employed discuss these agents landscapes integrated approaches. NSs as assets general control, some liabilities barriers adoption systems from legislative, economic, social standpoint.

Assessing the Impact of Insecticide Resistance on Vector Competence: A Review

Insects, Год журнала: 2022, Номер 13(4), С. 377 - 377

The primary strategy to avoid adverse impacts from insect-mediated pathogen transmission is the chemical control of vector populations through insecticides; its continued use has led insecticide resistance and unknown consequences on competence. This review aims systematically analyze synthesize research influence (IR) competence (VC). Thirty studies met inclusion criteria. Twenty studies, conducted either in laboratory or field settings, described phenotypic mechanisms VC vectors human pathogens. Seven showed effect exposure insecticides Three reported crop pests. evidence shows that IR could enhance, impair, have no direct laboratory-designed studies. Similar positive negative trends are found pest crops VC. Even though there can enhance VC, thus increasing risk transmission, more investigations needed confirm observed patterns what implications these factors programs.

A review on biology and possible management strategies of tomato leaf miner, Tuta absoluta (Meyrick), Lepidoptera: Gelechiidae in Nepal

Heliyon, Год журнала: 2023, Номер 9(6), С. e16474 - e16474

Опубликована: Май 21, 2023

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), Tomato Leaf Miner (TLM) moth, is one of the notorious oligophagous pests solanaceous crops that mines primarily on mesophyll leaves as well bore tomato fruits. In Nepal, T. absoluta, pest has a potential to create loss up 100%, was detected in 2016 commercial farm at Kathmandu. So, farmers and researchers must heed for effective management contrivance improve yield Nepal. The devastating nature causes its unusual proliferation so it needs dire study host range, damage sustainable strategies. We discussed data information available several research papers comprehensively provided succinct occurrence world, biology, life cycle, plants, due novel control tactics which helps farmers, researchers, policy makers sustainably rise production Nepal global context attain food security. Sustainable strategies such Integrated Pests Management (IPM) approaches incorporating prioritizing biological methods with usage chemical pesticides less toxic active ingredient can be encouraged controlling sustainably.
