Advances in the use of trapping systems for Rhynchophorus ferrugineus (Coleoptera: Curculionidae): traps and attractants.
Given the social importance related to the red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae), efforts are being made to develop new control methods, such as the deployment of trapping systems. In this work, the efficacy of a new black pyramidal trap design (Picusan) has been verified in comparison with white and black buckets. In addition, the attractant and synergi...
متن کاملSusceptibility and Immune Defence Mechanisms of Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) against Entomopathogenic Fungal Infections
Insects infected with entomopathogenic fungi, experience physiological changes that influence their growth and immune defence. The potential of nine isolates of entomopathogenic fungi was evaluated after determining percent germination and relative conidial hydrophobicity. However, nutritional indices were evaluated after immersing eighth-instar Rhynchophorus ferrugineus larvae into each isolat...
متن کاملSynonymy of Rhynchophorus ferrugineus (Olivier), 1790 and R. vulneratus (Panzer), 1798 (Coleoptera, Curculionidae, Rhynchophorinae)
Morphological, molecular-genetic and breeding data were collected to investigate the species status of the Asian palm weevils, Rhynchophorus ferrugineus (Olivier) and R. vulneratus (Panzer) (Coleoptera: Curculionidae). These weevils are distinguished by characteristic colouring of the pronota and elytra, but naturally occurring colour intermorphs were observed. Contrary to the literature, quant...
متن کاملDemographic comparison and population projection of Rhynchophorus ferrugineus (Coleoptera: Curculionidae) reared on sugarcane at different temperatures
Understanding how temperature affects fitness is important for conservation and pest management, especially in the era of global climate change. Rhynchophorus ferrugineus (Oliver) (Coleoptera: Curculionidae) is a worldwide pest of many economically important crops. Although much is known about this pest's life cycle, its adaptability to different temperatures is not fully understood. Here, we u...
متن کاملIdentification of pigmented Serratia marcescens symbiotically associated with Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae)
To characterize red pigment-producing bacteria (RPPB) regularly released during oviposition by red palm weevil (RPW), RPPB were recovered from eggs deposited in apples supplied as substrate for oviposition. The presence of RPPB was also detected from gut, the reproductive apparatus of dissected adult and virgin insects and from pupal cases collected within infested palms. RPPB were also identif...
