Based on laboratory studies on immature and mature fruits of lady's finger; the total period of all four nymphal stages lasted for 32.6 ± 4.17 days at an average room temperature of 28 ± 2ºC and 70-75% RH during September, 2009. Male mealybug has a short life span of 3.0 ± 0.21 days. Females live for nearly 80.7 ± 10.43 days with an oviposition period of approximately 21 days. Thi...

...iality. Among these, the polyphagous betelvine blackfly, Aleurocanthus rugosa Singh (Aleyrodidae: Hemiptera) is a major pest causing severe damage to the foliage in the conservatories (borojas) of West Bengal. The seasonal incidence of A. rugosa in boroja was recorded during 2003-2004. A. rugosa adults were active in the boroja throughout the year with two peaks, one in pre-monsoon and another in post-monsoon i.e., period prior initiation of winter season. Dur...

Control strategies of papaya mealybug, Paracoccus marginatus Williams & Willink infesting vegetable crops in Bangladesh
...ybug. P. marginatus is a polyphagous pest attacking several agricultural, horticultural crops, ornamental plants and weeds of economic value. The papaya mealybug feeds on the sap of the plants by inserting its stylets into the epidermis of the leaf as well as into the fruit and stem. In doing so, it injects a toxic substance into the leaves. The result is chlorosis, plant stunting, leaf deformation, early dropping of the leaves and fruits, a heavy accumulation...

...rch, 2011. It is a small polyphagous insect pest sucking saps from the attacking fruits and leaves. P. marginatus passes through egg and three nymphal stages to become adult. Generally, three and four nymphal instars occur in case of female and male mealybug, respectively. The adults are most active in warm, dry and humid weather. The male adult mealybugs possess two pairs of wings. Female have no wings and move by crawling short distances or by being blown in...

Biological control approach by using Aenasius bambawalei Hayat(Hymenoptera: Encyrtidae) has been developed recently to control this pest. However, the efficiency of this parasitoid is variable according to the locality and the plants on which P. solenopsis is feeding. In this context, this experiment investigated under field and laboratory c...

...isia tabaci (Genn.) is a polyphagous pest and is reported on more than 600 host plants worldwide. Different methods are being used for its control. The present experiment was conducted to determine the effect of some plant extracts of mint (Mentha spp.) and geranium (Pelargonium graveolens) and soybean oil (Glycine max), mustard oil (Brassica spp.) and taramera oil (Eruca sativa) against whitefly, Bemisia tabaci on sesame crop. The data were recorded 24h befor...
