Assessing the performance of YOLOv5 algorithm for detecting volunteer cotton plants in corn fields at three different growth stages

Artificial Intelligence in Agriculture, 2022
The feral or volunteer cotton (VC) plants when reach the pinhead squaring phase (5–6 leaf stage) can act as hosts for the boll weevil (Anthonomus grandis L.) pests.

Identification of Volatile Compounds Involved in Host Location by Anthonomus grandis (Coleoptera: Curculionidae)

Frontiers in Ecology and Evolution, 2018
Phytophagous insects rely on plant volatiles to locate suitable hosts upon which to feed or oviposit. The boll weevil, Anthonomus grandis, is the main pest on cotton crops in the Neotropical region and is attracted to host plant volatiles, especially ...

The oral secretion from Cotton Boll Weevil (Anthonomus grandis) induces defense responses in cotton (Gossypium spp) and Arabidopsis thaliana

Current Plant Biology, 2022
Cotton Boll Weevil (CBW, Anthonomus grandis) is a devastating insect-pest affecting cotton (Gossypium spp), using cotton internal floral structures for larval development, making it difficult to control. Little is known about the mechanism underlying CBW-

Proctolaelaps bickleyi (Acari: Mesostigmata: Melicharidae): First Record of Its Association with Cotton Boll Weevil

, 2020
The objective was to register the occurrence of Proctolaelaps bickleyi (Bram) (Acari: Mesostigmata: Melicharidae) in association with adults of the Anthonomus grandis Boheman (Coleoptera: Curculionidae) and to describe aspects of its behavior.

Survival and preference of cotton boll weevil adults for alternative food sources

Brazilian Journal of Biology
Plants that have potential as alternative food source (floral nectar, pollen and plant tissues) to the boll weevil during the intercropping season were evaluated considering the prevalent conditions of Cerrado in the Central Brazil.

Refuge by day, forage by night: Diel activity of vine weevil as characterised by smart monitoring

Agricultural and Forest Entomology, Volume 28, Issue 3, Page 508-514, August 2026.
Vine weevil activity was monitored using a Smart trap, which recorded diel refuge‐seeking behaviour. Increasing light intensity triggered refuge seeking behaviour, while lower light intensity induced forage seeking activity. Understanding vine weevil diel activity can enhance early detection, which can improve the effectiveness of integrated pest ...

Biology, Ecology, and Pest Management of the Tarnished Plant Bug, Lygus lineolaris (Palisot de Beauvois) in Southern Row Crops

Insects, 2021
The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), (Hemiptera: Miridae) is considered the most damaging pest of cotton (Gossypium hirsutum L.) in the mid-southern United States, although it is established throughout the United States ...

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

Journal of Applied Entomology, Volume 150, Issue 6, Page 736-742, July 2026.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.
