Genetic variation in avocado stem weevils Copturus aguacatae (Coleoptera: Curculionidae) in Mexico.

Taxonomic use of endophallus in weevils of the genus sitona (coleoptera : curculionidae)

Genetic profiling to determine potential origins of boll weevils (Coleoptera: Curculionidae) captured in a Texas eradication zone: endemicity, immigration, or sabotage?

Thirty-seven boll weevils, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), were captured in pheromone traps near Lubbock, TX, in the Southern High Plains/Caprock eradication zone during August-October 2006. No boll weevils had been captured in this zone or neighboring zones to the north earlier in the year, and only very low numbers had been captured in neighboring zones to the ...

“The Current Status of the Distribution Range of the Western Pine Beetle, Dendroctonus brevicomis (Curculionidae: Scolytinae) in Northern Mexico”

The distribution range of the western pine beetle Dendroctonus brevicomis LeConte (Coleoptera: Curculionidae) is supported only by scattered records in the northern parts of Mexico, suggesting that its populations may be marginal and rare in this region. In this study, we review the geographical distribution of D. brevicomis in northern Mexico and perform a geometric morphometric analysis of se...

A new species of <i>Cactopinus</i> Schwarz from central Mexico (Coleoptera: Curculionidae: Scolytinae).

A new species in the genus Cactopinus Schwarz is described from central Mexico bringing the total of known species to 22.

Boll Weevil (Anthonomus grandis Boheman) (Coleoptera: Curculionidae) Dispersal in the Southern United States: Evidence from Mitochondrial DNA Variation

An understanding of boll weevil (Anthonomus grandis Boheman) dispersal behavior is essential to characterizing and responding to the threat of migration into eradication zones. Genetic variation in boll weevil mitochondrial DNA (mtDNA) was sampled and analyzed to make inferences on the magnitude and geographic pattern of genetic differentiation among weevil populations from 20 locations across ...
