The external morphology of Austroplatypus incompertus (Schedl) (Coleoptera, Curculionidae, Platypodinae)
Previous descriptions of adult Austroplatypus incompertus (Schedl) are completed by the addition of descriptions and illustrations of the adults and, in particular, their maxillary palps. I describe and illustrate the non-adult phases of the life cycle and provide a key to the larval instars. The sexual dimorphism of Austroplatypus incompertus is atypical and includes a latitudinal cline which ...
متن کاملSYSTEMATICS, MORPHOLOGY AND PHYSIOLOGY Life History and Larval Morphology of Eurhinus magnificus Gyllenhal (Coleoptera: Curculionidae), a New Weevil to the United States
Eurhinus magnificus Gyllenhal has been collected in south Florida, presumably introduced through trade with countries in its native range. Very little information has been published on the biology or taxonomy of this insect. We conducted studies to investigate various aspects of its life history and host plant associations. The pre-imaginal life stages of E. magnificus are described for the fir...

Thepecanweevil,Curculio caryae (Horn), and its primaryhost, pecan,Carya illinoinensis (Wagenheim) K. Kochare indigenous to North America east of the Rocky Mountains. This review is presented to describe the biology, life stages, crop injury, monitoring approaches, and primary control strategies currently used for pecan weevil in pecan. Suggested economic thresholds are extrapolated from several...
متن کاملSitona lineatus (Coleoptera: Curculionidae) Larval Feeding on Pisum sativum L. Affects Soil and Plant Nitrogen
Adults of Sitona lineatus (pea leaf weevil, PLW) feed on foliage of several Fabaceae species but larvae prefer to feed on nodules of Pisum sativum L. and Vicia faba L. Indirectly, through their feeding on rhizobia, weevils can reduce soil and plant available nitrogen (N). However, initial soil N can reduce nodulation and damage by the weevil and reduce control requirements. Understanding these ...
متن کاملDoes White Clover (Trifolium repens) Abundance in Temperate Pastures Determine Sitona obsoletus (Coleoptera: Curculionidae) Larval Populations?
To determine if host plant abundance determined the size of clover root weevil (CRW) Sitona obsoletus larval populations, a study was conducted over 4 years in plots sown in ryegrass (Lolium perenne) (cv. Nui) sown at either 6 or 30 kg/ha and white clover (Trifolium repens) sown at a uniform rate of 8 kg/ha. This provided a range of % white clover content to investigate CRW population establish...
