An overview of available literature on use of plant products against the storage beetles in tropical regions is presented in order to highlight the importance, safe use, and effective control.
Potential of four vegetable oils and ten botanical powders for reducing infestation of cowpeas by Callosobruchus maculatus, C. chinesis and C. rhodesianus
Spectral characterization and LAI modelling for the tea ( Camellia sinensis (L.) O. Kuntze) canopy
Understanding the spectral characteristics of tea plants is important in monitoring tea plantations by remote sensing. Westhall tea estate, Kataboola, situated in the Kandy district in Sri Lanka, was…
The potential use of indigenous plant materials against Callosobruchus chinensis L . and Callosobruchus maculatus L . ( Coleoptera , Bruchidae ) in stored legumes in Sri Lanka
Pulse beetles Callosobruchus chinensis and Callosobruchus maculatus are the most serious pests in stored legumes in majority of tropical countries. Attention has been given to the possible use of…
Pesticidal potential of some selected tropical plant extracts against Callosobruchus maculates (F) and Callosobruchus chinensis (L) (Coleoptera: Bruchidae).
Plant oils obtained from leaves and other parts of 20 different plant species were bioassayed under laboratory conditions for their ability to protect stored legumes from damage by cowpea weevil and adzuki bean seed weevil.
Tender Leaf Extract of Terminalia catappa Antinociceptive Activity in Rats
It was concluded that T. catappa leaf extract is useful as an analgesic but not as an antihyperalgesic in mild to moderate pain, supporting its folklore use in Sri Lanka.
Effect of Host Age, Parasitoid Age and Temperature on Interspecific Competition Between Chelonus Insularis Cresson, Cotesia Marginiventris Cresson and Microplitis Manilae Ashmead
The effects of host age, age of Cotesia marginiventris Cresson adults and temperature on interspecific competition between fall army worm (FAW), Spodoptera frugiperda (J. E. Smith), larval…

Repellent Properties of Plant Oil Vapours on Pulse Beetle ( Callasobruchus maculatus L.) (Coleoptera: Bruchidae) in Stored Green Gram ( Vigna radiata Walp.)
Citronella oil, Neem oil, Cinnamon leaf oil and Cinnamon bark oil vapours recorded significantly lowest number of pulse beetles after infestation and their oviposition and adult emergence indicating the highest repellent action and toxic effects.
