Parasitoids of boll weevil Anthonomus grandis and resident predators in kaolin-treated cotton

Semina: Ciências Agrárias, 2013
Simultaneous use of control methods is essential to reach success in managing arthropod pests. The current study investigated the effect of kaolin application on resident predators in the cotton plant canopy and parasitism of boll weevil on abscised ...

Artificial fruits and nuts for studying predation of cryptic prey: a case of 3D‐printed coffee berries for studying predation of coffee berry borer by flat bark beetles

Entomologia Experimentalis et Applicata, Volume 171, Issue 9, Page 716-720, September 2023., 2023
Studying the effects of predation in cryptic herbivorous insects is difficult because many spend all or most of their life cycle inside their host plant. Here, we designed and 3D‐printed artificial coffee berries to study predation of coffee berry borer, Hypothenemus hampei (Coleoptera: Curculionidae, Scolytinae) by flat bark beetles, Cathartus ...

Prey‐mediated effects of mCry51Aa2‐producing cotton on the predatory nontarget bug Orius majusculus (Reuter)

Insect Science, Volume 30, Issue 4, Page 1191-1206, August 2023., 2023
While genetically engineered Bt cotton producing insecticidal mCry51Aa2 is protected against plant bugs, beneficial predatory pirate bugs are also sensitive if exposed continuously to high concentrations. When a mix of prey with high and low toxin content was provided, when alternative prey species with lower concentrations were provided, or when ...

Development, survival and morphometric parameters of boll weevil reared in different photoperiods [PDF]

Brazilian Journal of Biology
Third instar larvae of the cotton boll weevil, Anthonomus grandis grandis (Boheman) (Coleoptera: Curculionidae) are offered to the parasitoid Jaliscoa grandis Burks, 1954 (=Catolaccus grandis) (Hymenoptera: Pteromalidae) for mass-rearing.

A CC-NB-ARC-LRR Gene Regulates Bract Morphology in Cotton. [PDF]

Adv Sci (Weinh)
This research article focuses on cotton bracts. The authors clone the gene of the frego bract, construct a single‐cell atlas of cotton and excavate genes related to bract type‐related and analyze the mechanism of the different cell morphology of the two bracts.

Rational Practices to Manage Boll Weevils Colonization and Population Growth on Family Farms in the Semiárido Region of Brazil

Insects, 2014
Because boll weevil, Anthonomus grandis Boh. develops partially protected inside cotton fruiting structures, once they become established in a field, they are difficult to control, even with nearly continuous insecticide spray.

Population genomics and phylogeography of the boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae), in the United States, northern Mexico, and Argentina

Evolutionary Applications, 2021
The boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae), is an important pest of commercial cotton across the Americas. In the United States, eradication of this species is complicated by re‐infestations of areas where eradication has ...

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

Pesquisa 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.

Stink Bugs and Leaffooted Bugs Are Important Fruit, Nut, Seed and Vegetable Pests

EDIS, 2005
Stink bugs (Pentatomidae) and leaffooted bugs (Coreidae) are important direct pests of many seed, fruit, vegetable and nut crops. Recently they have become serious pests of cotton because of the reduction in pesticide use resulting from the eradication ...

Stability and tissue-specific Cry10Aa overexpression improves cotton resistance to the cotton boll weevil. [PDF]

, 2020
The cotton boll weevil (CBW, Anthonomus grandis) is the most destructive cotton insect pest affecting cotton crops. To overcome this problem, CBW-resistant genetically modified cotton plants overexpressing Bacillus thuringiensis entomotoxins were ...
