Circadian rhythms of feeding, oviposition, and emergence of the boll weevil (Coleoptera: Curculionidae) [PDF]

open access: yes, 2006
Circadian rhythm of feeding, oviposition, and emergence of boll weevil adults were determined at five different photophases (24, 14, 12, 10, and 0 hours) and a constant 27°C temperature, 65% RH in the laboratory.

Infestation of Anthonomus grandis (Coleoptera: Curculionidae) on re-sprout of cotton plants

open access: yesPesquisa Agropecuária Tropical, 2015
The destruction of cotton crop residues at the end of the crop cycle is a key strategy for the phytosanitary crop management, since its off-season re-sprout can provide sites for feeding and oviposition of pests such as the boll weevil.
