A community of frugivorous weevils was studied by quantitative rearing of 57 weevil species represented by 10 485 individuals from 326 woody plant species in lowland rain forest in Papua New Guinea. Only fruits from 35% of plant species were attacked by weevils. On average, weevils were reared from only 1 in 33 fruits and 1 kg of fruit was attacked by 2.51 individuals. Weevil host specificity w...

The problem of degradation of agricultural residues from palm oil industry is increasing due to its expansion. Lignocelloulosic waste from these industry represent large amount of unutilized resources, this is due to their high lignin content. Since white rot fungi are capable of degrading lignin, its potential for the degradation of lignocelloulosic waste from palm oil industry was accessed. T...

Sterile insect technique (SIT) control method is integrated in many ongoing area-wide programs for Ceratitis capitata W. management who largely depends on the sterile male competitiveness. The use of semiochemical supplements originated from host and non-host plant materials to better manage physical conditions handling C. males fly emergence release facilities improve cost-effectiveness SIT wo...

Stromules are motile extensions of the plastid envelope membrane, whose roles are not fully understood. They are present on all plastid types but are more common and extensive on non-green plastids that are sparsely distributed within the cell. During tomato fruit ripening, chloroplasts in the mesocarp tissue differentiate into chromoplasts and undergo major shifts in morphology. In order to un...

Major soluble proteins of grapevine ripe berries were extracted from six different cultivars including non vinifera, with trichloroacetic acid acetone and resolved in two-dimensional electrophoresis (2-DE) gels. About three hundred spots were detected on the 2-DE map after colloidal blue staining. From 2-DE map of cv. Gamay mesocarp, 67 proteins were identified (p > 0.95) using matrix-assisted ...
