Effects of four tropical plant (Aframomum melegueta, Zanthoxylum zanthoxyloides, Piper guineense and Eugenia aromatica) were investigated under tropical laboratory storage conditions for the protection of cowpea seeds against insect infestation. The plant materials were pulverised into fine powder after air drying and admixed with 20 g of cowpea seeds at the ...

Callosobruchus maculatus (Fab.) (C. maculatus) is one of the major pests legume seeds in storage causing significant damage, leading to food insecurity and low income for farmers. This work was planned develop eco-friendly agents from essential oils Artemisia herba alba Asso. (AEO), Maticaria Recutita L. (MEO), Dittrichia Viscosa (DEO) control C. maculatus. To achieve this goal, (EOs) were extr...

Callosobruchus maculatus F. (Coleoptera; Bruchidae) is one of the most important storage pests, especially in legumes, which causes significant damage many parts Iran, including east Azarbaijan province. This study aimed to isolate and identify insect-associated bacteria with this pest then evaluate capability these bacterial isolates biocontrol insect laboratory conditions. Stock culture C. wa...

essential oil extracted from the leaves of myrtle, myrtus communis l. (myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (tribolium confusum and callosobruchus maculatus). the chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (gc-ms). the major oil components were α-pinene (10.4%), α- terpineol (10.1%), linalool (9.0%...

Despite the fact that many plant-feeding insects are pests, little effort has been made to identify key evolutionary trait transitions that allow taxa to acquire or lose pest status. A large proportion of species in the genus Callosobruchus are economically important pests of stored, dry postharvest beans of the tribe Phaseoleae. However, the evolution of this feeding habit is poorly understood...

This study investigated the acaricidal and insecticidal effect of local lupin (Lupinus albus L. Fabaceae) seed extract against Tetranychus urticae Koch (Acari: Tetranychidae), Callosobruchus maculatus F. (Coleoptera: Chrysomelidae), Plodia interpunctella (Hubner) (Lepidoptera: Pyralidae) metabolite content seeds. In tests for T. leaf-disk bioassay was employed. Contrarily, two μL were topically...
