Digestive proteases during development of larvae of red palm weevil, Rhynchophorus ferrugineus (Olivier, 1790) (Coleoptera: Curculionidae).
The evolution of digestive proteases during larval development of Rhynchophorus ferrugineus (Olivier, 1790) has been studied. A progressive increase of protease activity has been found. The optimum pH for proteolytic activity against azocasein was determined. Caseinograms revealed an active complex of alkaline proteases from the early stages of the development. From the apparent molecular masse...

Development of red date palm weevil Rhynchophorus ferrugineus (Olivier) was evaluated on 4 popular cultivars of date palm, viz., ‘Khalas’, ‘Sukkary’, ‘Khasab’, and ‘Sillaj’ for 2 consecutive generations. The weevils reared on ‘Sukkary’ showed significantly better growth expressed in most parameters such as length, width and weight at larval, pupal and adult stages. Significantly greater numbers...
متن کاملThe Gut Entomotype of Red Palm Weevil Rhynchophorus ferrugineus Olivier (Coleoptera: Dryophthoridae) and Their Effect on Host Nutrition Metabolism
For invasive insects, the potential roles of gut microbiota in exploiting new food resources and spreading remain elusive. Red palm weevil (RPW), Rhynchophorus ferrugineus Olivier, is an invasive destructive pest which feeds on nutrient-poor tender tissues and has caused extensive mortality of palm trees. The microbes associated with insects can improve their nutrition assimilation. However, ex...

Date palm, phoenix dactylifera l. (arecales: arecaeae) is the most important crop of the arabian Peninsula. the Kingdom of Saudi arabia is among the top 3 date producing countries of the world estimated to have over 400 date palm cultivars of which 25 are important and yield 1.3 million tons of dates annually. the red palm weevil (RPW) Rhynchophorus ferrugineus (olivier) (Coleoptera: Curculioni...
متن کاملEfficacy of aggregation pheromone in trapping red palm weevil (Rhynchophorus ferrugineus Olivier) and rhinoceros beetle (Oryctes rhinoceros Linn.) from infested coconut palms.
Red palm weevil and Rhinoceros beetle are the major pests inflicting severe damage to coconut palms. Due to ineffectiveness of the current management practices to control the two important pests on coconut, a study was conducted to know the attractiveness of red palm weevil and rhinoceros beetle to aggregation pheromone. Olfactometer studies indicated that the aggregation pheromone of red palm ...
