Fungal seed treatments of cotton affect boll weevil development

Pest Management Science, 2023
AbstractBACKGROUNDNonpathogenic fungi associated with plants can enhance plant defenses against stress factors, including herbivory. This study assessed whether cotton plants grown from seeds treated with different fungi affected boll weevil, Anthonomus grandis grandis Boheman, development and reproduction along with plant tolerance.

From flower buds to bolls: how cotton reproductive structures shape boll weevil development, reproduction and survival. [PDF]

Pest Manag Sci
Female boll weevils feeding on flower buds promote reproduction regardless of their immature diet, whereas boll feeding increases lipid reserves and lifespan, revealing a nutrition‐driven trade‐off that sustains survival and reproduction in tropical boll weevil populations.

EVALUATION OF THE SUSCEPTIBILITY OF THE BOLL WEEVIL (Anthonomus grandis, BOHEMAN) TO MALATHION IN THE LAGUNA REGION

Tropical and Subtropical Agroecosystems, 2022
Background. Resistance to an insecticide is what determines its effectiveness and the lack of information limits effectiveness in the control of the boll weevil in cotton crops. Objective. The objective of the study was to determine the susceptibility of
