A review on ecology, biology, and management of a detrimental pest, Tuta absoluta (Lepidoptera: Gelechiidae)

Abstract

Insect pests are the forcing barrier for crop production worldwide. Of those insects, lepidopteran forms a major group of pests damaging from larval, pupal to adult stages. A leaf-mining insect i.e., Tuta absoluta of the lepidopteran group is a serious pest of tomato throughout the globe. The widespread outreach resulting from this challenging pest posed a great threat in every habituated continent recently. The extensive infestations fortified by feeding grubs on tomato and other Solanaceous crops have unprecedented economic losses of the yield. Due to the entophytic nature of the pest, it makes growers difficult to manage the tomato leaf miner pest. So, every approach is to be foreseen to manipulate the pest environment not favoring them for survival, multiplication, and growth. Thence, a complete package of useful tactics including physical, biological, mechanical, biotechnical, botanical, and chemical measures are fruitful to harness the real impact of pest management. The best control strategies are accessed and complied herein considering the actual know-how on the nature of pests and effective mitigating measures to assure the crops in this review paper.

Insights into the germplasm conservation and utilization: Implications for sustainable agriculture and future crop improvement

“…By conserving diverse germplasm, researchers can identify and utilize genes for pest resistance in crop breeding programs, ultimately leading to the development of pestresistant crop varieties (Sharma et al, 2022;Yadav et al, 2023a). This integrated pest management approach reduces reliance on chemical pesticides and promotes sustainable agricultural practices (Yadav et al, 2022a;Yadav et al, 2022b). Additionally, botanical and sterile insect techniques offer environmentally friendly pest management options that can be integrated into germplasm conservation strategies (Yadav et al, 2022c;Yadav et al, 2022d).…”

Farmer’s perception on Chinese citrus fruit fly (CFFs) and its management in Solukhumbu and Sindhuli district of Nepal

“…Respondents were categorized based on their knowledge extent, with proportions in Solukhumbu and Sindhuli identified as essential (16.67% and 53.33%), intermediate (9.26% and 33.33%), and high (5.56% and 10%), respectively. According to Yadav et al (2022a), the information on damage symptoms aids in identification of pest. Therefore, the identification of drop fruit symptoms was reported by 31.48% and 33.33% of respondents in Solukhumbu and Sindhuli, respectively, while higher levels of awareness were seen for symptoms preceding fruit drop in Sindhuli (50% compared to 14.81% in Solukhumbu).…”

A Review on the Biology, Ecology, and Management Tactics of Helicoverpa armigera (Lepidoptera: Noctuidae)

“…A normal mating between an untreated female and an irradiated male insect produces progeny with aberrant characteristics. As a result, this sterility technique may be effectively used since it won't interfere with any pest control plans (Yadav, Bhattarai, et al, 2022;Yadav, Sharma, et al, 2022).…”

“…These strategies fit under the broad categories of cultural control, host plant resistance, chemical control, and biological control (Figure 5) (Mapuranga et al, 2015). It may be possible to effectively manage any pest without harming the environment by combining various pest control methods and making appropriate use of insect sprays that are less harmful to the environment (Yadav, Bhattarai, et al, 2022). The most successful IPM modules for controlling pod borer include pheromone trapping, the sequential release of the biocontrol agent (Trichogramma chilonis + Bracon hebetor), and spraying neem seed kernel extract.…”
