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

open access: yesFrontiers 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]

open access: yesJournal of Chemical Ecology, 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. Moreover, this preference was paralleled by the release of the acyclic homoterpenes (tetranorterpenes) (E)-4,8 ...

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

open access: yesJournal 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.

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, Volume 82, Issue 6, Page 5757-5766, June 2026.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Composition and Diversity Characteristics of Gut Microbiota during the Development of Telchinia issoria (Lepidoptera: Nymphalidae)

open access: yesEcology 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
