Validation of weather based forewarning model for Helicoverpa armigera in chickpea

The Indian Journal of Agricultural Sciences, 2019
Weather based forewarning model for Helicoverpa armigera developed earlier was validated by recording the activity of H. armigera through pheromone trap catches in chickpea sown during rabi 2017–18 at IARI, New Delhi. The moth activity of H.

Development of PCR, LAMP and HRM‐Based Molecular Species Diagnostic Tools for Identifying Four Agricultural Pests in the Genus Helicoverpa (Lepidoptera: Noctuidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.

Scientific Opinion on the pest categorisation of Helicoverpa armigera (Hübner) [PDF]

EFSA Journal, 2014
Abstract The Panel on Plant Health undertook a pest categorisation of Helicoverpa armigera for the European Union territory. The taxonomy of H. armigera and related species worldwide is complex but, in Europe, only H. armigera is present. Although it has been recorded in all Member States, it persists throughout the year only in the southernmost parts ...

Novel alphabaculovirus isolated from Helicoverpa armigera (Lepidoptera: Noctuidae) in Iran: characterization and pathogenicity [PDF]

نامه انجمن حشره‌شناسی ایران
A novel alphabaculovirus, originally isolated from Helicoverpa armigera dead larvae, was collected from a tomato field in the North West region of Iran. Preliminary virus infection was revealed by microscopic observation of irregularly shaped polyhedral ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

Pest Management Science, Volume 82, Issue 6, Page 5757-5766, June 2026.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Insights on the nutritional ecology of a nocturnal pollinating insect

Insect Science, Volume 33, Issue 3, Page 1123-1141, June 2026.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.
