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

Abstract

In the agronomical field, different internal and external factors are responsible for substantially diminished crop harvest. A hindrance that can be listed in those factors is insect pests. African bollworm (Helicoverpa armigera) is a significant polyphagous, rapacious feeder, and the serious pest of agricultural cosmos. This pest can infest a wide array of species (almost 180 plant species) and a diverse range of families regarding it to be the most versatile and economically important nuisances for crops. H. armigera is widely far-reaching throughout the globe mostly in the Asian domain. Likewise, the subsequent number of instars makes it more detrimental and positively influences its existence pattern. The biological parameters like high fecundity, reproducibility, and comparatively long-life period support in the incitement of damage threshold (DT). Thusly, this article depicts the presentation and control tactics against H. armigera, and further incorporates science and damage to acquaint this pest and access raise in production.

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

“…Notably, 48.15% of respondents in Solukhumbu were unaware of damage symptoms, contrasting with only 6.67% in Sindhuli. The information on lifecycle and behavior of the pest plays a vital role in the management of pests; the higher the information about lifecycle and behavior higher will change of management (Yadav et al, 2022b). In Solukhumbu, a mere 14.82% of respondents understood fly lifecycle and behavior, with none possessing extensive information.…”

Exploring Agroecological Approaches for Sustainable Agriculture and Rural Development: A Comprehensive Review

“…In-depth examinations of the ecological effects of cultivation, grazing, irrigation, and fertilization on the soil ecosystem are essential. Solutions are recommended to maintain a healthy, productive soil and crop ecosystem, considering negative effects of pesticides and proposing alternatives such as biological control, crop rotation and diversity, sanitation, and innovative chemical attractants and technology, deterrents [21,22] and plant resistance [23,24]. The symbiotic relationship between arbuscular mycorrhizal (AM) fungi and plant roots is highlighted for its role in enhancing plant nutrient uptake and providing nonnutritional benefits such as soil stabilization, erosion prevention, and alleviation of plant stress caused by various factors [18].…”
