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 ...

Influence of two acyclic homoterpenes (Tetranorterpenes) on the foraging behavior of anthonomus grandis Boh [PDF]
, 2016 Previous studies have shown that the boll weevil, Anthonomus grandis, is attracted to constitutive and conspecific herbivore-induced cotton volatiles, preferring the blend emitted by cotton at the reproductive over the vegetative stage.

Ecology and Evolution, Volume 16, Issue 5, May 2026.Ramie (Boehmeria nivea) is a traditional economic crop of high commercial value, whose cultivation is threatened by the leaf‐feeding pest Telchinia issoria. This study investigated how the gut microbiota of T. issoria shifts across its larval, pupal, and adult stages using 16S rRNA amplicon sequencing. ABSTRACT Ramie (Boehmeria nivea) was a traditional

Diapause in the Boll Weevil, Anthonontus grandis Boheman, As Related to Fruiting Activity in the Cotton Plant [PDF]
, 1973 Studies in Arkansas show that boll weevil diapause is related to changes in fruiting activity of the cotton plant. Generally, when larval development took place while fruiting levels were increasing or being held at a high level, diapause in resulting ...

‘Retournement’ of the aedeagus in Curculionidae (Coleoptera, Curculionoidea) [PDF]
, 2013 Retournement or turning of the aedeagus about its longitudinal axis through about 180o during development is known in Chrysomeloidea (Coleoptera). This change in the orientation of the organ may be observed during the postembryonic development.

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 ...

A Simulation Model Examining Boll Weevil Dispersal: Historical and Current Situations [PDF]
, 2017 A linear deterministic simulation model was developed to examine the historical rate of movement of the boll weevil, Anthonomus grandis grandis Boheman, across the southeastern United States.

Resource Availability Modulates Gene Expression Across Life Stages in a Migratory Butterfly
Molecular Ecology, Volume 35, Issue 5, March 2026.ABSTRACT Natural populations are in constant need of balancing resource allocation to compensate for seasonal environmental variation. In many insects, a well‐established trade‐off between migration and reproduction exists. While this trade‐off has been characterised phenotypically for decades, the underlying regulatory pathways are poorly understood ...

Plant, Cell &Environment, Volume 49, Issue 3, Page 1424-1438, March 2026.ABSTRACT Insect‐derived molecular cues can prime plant defences against herbivore attack. The genes that are sensitive to priming, and how their expression changes on the scale of days, have not been fully resolved. Moreover, priming may affect interactions with insects that are not the source of the priming cue.
