Cossonid Weevils (Coleoptera: Curculionidae) Infested on Wood Cultural Properties

Towards a phylogenetic system of derelomine flower weevils (Coleoptera: Curculionidae)

A revised phylogenetic classification for derelomine flower weevils (Coleoptera: Curculionidae: Curculioninae: Derelomini Lacordaire) is proposed, based on a cladistic analysis of 115 outgroup and ingroup taxa and 155 primarily morphological characters. The single most-parsimonious cladogram (length 1⁄4 271, consistency index 1⁄4 65, retention index 1⁄4 95) indicates that several genera must be...

Pollination of Anthurium (Araceae) by derelomine flower weevils (Coleoptera: Curculionidae).

Cyclanthura flower weevils (Coleoptera: Curculionidae: Derelomini) are identified for the first time as pollinators of multiple species of Anthurium (Araceae) in Costa Rica. The weevils are present on the inflorescences in small numbers during the pistillate and staminate phase of anthesis, and consume plant tissues and pollen. The individuals of one species of Cyclanthura can visit several Ant...

Longevity of Overwintered Boll Weevils (Coleoptera: Curculionidae) On Pre-fruiting Cotton

Field-cage studies have indicated that prefruiting cotton (Gossypium hirsutum L.) is not nutritionally adequate to support extended longevity of overwintered boll weevils (Anthonomus grandis Boheman), but these studies did not separate the respective effects of environment and nutrition on survival. The longevity of trapcaptured overwintered weevils fed pre-fruiting cotton under controlled cond...

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

Mutual Interference of Pheromone Traps Within Trap Lines on Captures of Boll Weevils (Coleoptera: Curculionidae)

Traps baitedwith the synthetic aggregation pheromoneof the bollweevil (Anthonomus grandis Boheman) are often used to monitor population ßuctuations, distribution, and behavior. However, many factors generate variability in daily captures, making interpretation of trapping data difÞcult. Previous studies have shown that wind speed in the microenvironment around a trap can greatly affect numbers ...
