Larvae of longhorned beetles (Coleoptera; Cerambycidae) have evolved a diverse and phylogenetically conserved array of plant cell wall degrading enzymes

Systematic Entomology, Volume 46, Issue 4, Page 784-797, October 2021., 2021
We addressed the numbers, kinds and evolution of cerambycid plant cell wall degrading enzymes (PCWDEs) by surveying larval midgut transcriptomes from 23 species representing six of the eight recognized subfamilies of Cerambycidae. We identified 340 new putative PCWDEs belonging to ten carbohydrate active enzyme families, including two gene families ...

A major forest insect pest, the pine weevil Hylobius abietis, is more susceptible to Diptera‐ than Coleoptera‐targeted Bacillus thuringiensis strains

Pest Management Science, Volume 77, Issue 3, Page 1303-1315, March 2021., 2021
Effects of Bacillus thuringiensis on the pine weevil Hylobius abietis were evaluated for the first time. A Diptera‐targeted strain was most toxic and could enhance forest protection against H. abietis. Abstract BACKGROUND The pine weevil (Hylobius abietis) is a major forest regeneration pest causing high levels of seedling mortality and economic losses.

Intrasexual mounting in the beetleDiaprepes abbreviatus(L.) [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2000
The weevil Diaprepes abbreviatus shows three kinds of same-sex mountings: males mount other unpaired males, males mount males already engaged in copulation and females mount other females. Four hypotheses were evaluated in order to explain same-sex matings by males: (i) female mimicry by inferior males, (ii) dominance of larger males which affects the ...

Plants use identical inhibitors to protect their cell wall pectin against microbes and insects

Ecology and Evolution, Volume 10, Issue 8, Page 3814-3824, April 2020., 2020
Whether polygalacturonase‐inhibiting proteins (PGIPs) play a role in defense against herbivorous beetles is unknown. Feeding assays with the leaf beetle Phaedon cochleariae on Arabidopsis thaliana pgip mutants were performed. Fitness was increased when larvae were fed on mutant plants compared to wild‐type plants.

Los cromosomas de Diaprepes abbreviatus

The Journal of Agriculture of the University of Puerto Rico, 1990
La vaquita, Diaprepes obbreviatus, tiene cromosomas típicos de los picudos bisexuales de la subfamilia Otiorrhynchinae: 2n = 22; 2X (♀) ; 2n = 22; X, y (â™,). La meioformula del macho es 10 + Xyp . Los autosomas forman una serie de tamaños que varía gradualmente de más grandes a más pequeños.

RELATIONS PLANTE-INSECTES ET INSECTES-INSECTES CHEZ LE CHARANCON DES AGRUMES Diaprepes abbreviatus L (COLEOPTERA : CURCULIONIDAE) [PDF]

, 2017
Aux Antilles françaises, un grave problème de dépérissement en agrumiculÎure est apparu seulement quelques années après la plantation des premiers vergers. Un ravageur est en partie responsable de ce phénomène, le charançon Diaprepes abbreviatus dont les
