Size-dependent feeding and reproduction by boll weevil (Coleoptera: Curculionidae).
The considerable variation in adult size of the boll weevil, Anthonomus grandis grandis Boheman, has been well documented, but the influences of adult size on reproductive rate are not known. We examined the relationship between the size of boll weevils and their feeding and oviposition. Weevils weighed to the nearest milligram were grouped into five categories based on pupal weight: < or =5, 6...
متن کاملLady Beetles as Potential Predators of the Root Weevil Diaprepes Abbreviatus (coleoptera: Curculionidae) in Florida Citrus

Adult females lay eggs in masses sealed between leaves in the citrus canopy, and recently-hatched neonate larvae drop to the soil and feed on roots. The coccinellid species, Cycloneda sanguinea (L.), Harmonia axyridis Pallas, and Olla v-nigrum Mulsant, are generalist predators that consume a wide range of citrus pests, although they ...
متن کاملInfluence of Different Cotton Fruit Sizes on Boll Weevil (Coleoptera: Curculionidae) Oviposition and Survival to Adulthood
Understanding the critical host plant factors that determine oviposition behavior and survival of boll weevil, Anthonomus grandis grandis Boheman, on cotton, Gossypium hirsutum L., is important for developing successful pest management strategies. However, published information is both conßicting and limited regarding how different cotton fruit sizes affect boll weevil oviposition choices and s...
متن کاملThe coffee bean sign
An 89-year-old woman presented to our emergency department (ED) with a 4-day history of abdominal pain and vomiting. The physical exam revealed hypotension and a distended abdomen with generalized tenderness. Laboratory studies revealed hyperkalemia and elevated creatinine, lactate, and troponin. Given her hemodynamic instability, an emergent noncontrast abdominal computed tomography (CT) was o...
متن کاملMango seed weevil (Coleoptera: Curculionidae) and premature fruit drop in mangoes.
The effect of infestations of mango seed weevil, Sternochetus mangiferae (F.), on premature fruit drop of mangoes was investigated. Mango fruits ('Haden') of equal size were collected both off the ground and from the tree at four times during the season (June-August). If weevil-infested fruit were more prone to dropping than uninfested fruit, the prediction was that a higher infestation rate wo...
