Microwave-Assisted Enantioselective Synthesis of (2R,5S)-Theaspirane: A Green Chemistry Approach [PDF]

Molecules
The banana weevil (Cosmopolites sordidus) is a significant pest that reduces banana yields and can result in plant mortality. (2R,5S)-theaspirane, a kairomone from senesced banana leaves, is one of the natural banana volatiles, aiding weevil attraction ...

Visual Cues Are Relevant in Behavioral Control Measures for Cosmopolites sordidus (Coleoptera: Curculionidae) [PDF]

Journal of Economic Entomology, 2011
Trap designs for banana root borer, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), have been done essentially on the understanding that C. sordidus rely primarily on chemical cues. Our present results indicate that these borers also rely on visual cues.

First phylogenetic analysis of Dryophthorinae (Coleoptera, Curculionidae) based on structural alignment of ribosomal DNA reveals Cenozoic diversification. [PDF]

Ecol Evol, 2021
This study presents the first phylogeny of the palm weevil subfamily Dryophthorinae (1,200 species, 153 genera), a group that is mainly associated with monocots and includes major pests, such as the Red and South American Palm Weevils. This study includes genetic sampling of all major lineages worldwide, integrated structural alignment of ribosomal DNA

Stop me if you can: quantification of the effect of interfaces between plots on the dispersal of Cosmopolites sordidus

Pest Management Science, Volume 79, Issue 12, Page 5106-5115, December 2023., 2023
Cosmopolites sordidus that is dispersing by crawling had contrasted capacities to cross interfaces between plots. Some interfaces slow down dispersal and can thus be implemented in management strategies. Abstract BACKGROUND Cosmopolites sordidus is one of the most damaging pests of banana worldwide.

Decoding attraction: Improving vine weevil monitoring by exploiting key sensory cues

Pest Management Science, Volume 79, Issue 11, Page 4635-4643, November 2023., 2023
Vine weevil adults preferred black, tall and large‐diameter monitoring tools. Monitoring tool density influenced the number of vine weevils recorded in monitoring tools. By contrast plant density did not influence the number of weevils recorded in monitoring tools.

Susceptibility of Eucalyptus trees to defoliation by the Eucalyptus snout beetle, Gonipterus sp. n. 2, is enhanced by high foliar contents of 1,8‐cineole, oxalic acid and sucrose and low contents of palmitic and shikimic acid

Plant, Cell &Environment, Volume 46, Issue 11, Page 3481-3500, November 2023., 2023
Abstract Gonipterus sp. n. 2 (Coleoptera, Curculionidae) is an invasive, commercially important weevil that causes large‐scale defoliation of Eucalyptus trees. The weevil specifically feeds on young leaves and new shoots, thus reducing tree growth. The weevil displays a very strong preference for certain Eucalyptus genotypes, however, this behaviour ...
