“…The adult period which was about around two weeks reported by these authors was longer compared to the results of the presented study. This confirmed the observations of Coudriet et al (1985) that the development of whitefly species from egg to adult was different according to the host plant it fed on. The egg deposition pattern of A. dispersus reported by Wijesekara and Kudagamage (1990) on guava was observed on cassava too.…”

“…Among the two identified species B. tabaci is indigenous to tropical and subtropical regions of the world, and considered as a virus vector associated with certain crop and weed species (Byrne and Houck 1990;Coudriet et al 1985;Dittrich et al 1986;Ramani et al 2002;Schuster et al 1991). B. tabaci was recorded as a vector of Cassava mosaic virus in different countries of the tropical and subtropical regions (Fargette and Fauquet 1988;Fargette et al 1990;Palaniswami and Pillai 1990).…”

A survey in four distant locations: Anuradhapura, Madampe, Sri Jayewardenapura and Uda Walawe of Sri Lanka to identify the whitefly species related to cassava revealed two species, namely Bemisia tabaci (Gennadius) and Alerodicus dispersus (Russell). The species B. tabaci was recorded in all four surveyed locations, while A. dispersus was collected only from the first three locations.The results of the study on the pest life cycle under the laboratory conditions showed that, B. tabaci and A. dispersus passed through four nymphal instars before the adult stage. The mean duration values of these stages were 7.2, 7.5, 4.7, 5.6 and 8.5, 6, 9, 9 days respectively for the two species. The total duration of the life cycle of B. tabaci ranged from 22-57 days at the temperature of 29±2°C with a mean of 37.5 while that of A. dispersus was 27-68 days with a mean of 48 respectively (at 28±2°C).The damage to crop plants caused by two whitefly species is discussed with a special emphasis on their ability to transmit viral diseases.

“…When the new leaves had appeared, the secondary leaves reached their maturity and the level or stratum changed to the middle stratum. Furthermore, larval and pupal stages had longer life cycle, which was about 23.6 days at 25°C (Coudriet et al, 1985). Hence the larvae and pupae were mainly found at the middle stratum.…”

Population Ecology of Whitefly, Bemisia tabaci, (Homoptera: Aleyrodidae) on Brinjal

Whitefly, Bemisia tabaci (Gennadius), a common insect feeding on plants, belongs to the family Aleyrodidae of the order Homoptera. The quantity of food source especially brinjal, is one of the major factors that has attracted whitefly in the area. In fact, the flight ability of whitefly enables them to search for food quickly. Thus could encourage whitefly to reproduce in great numbers and subsequently cause severe infestation in the fields. Many farmers are not interested to grow brinjal after they have gone through some bad experience due to some whitefly infestations, which have resulted in a total crop loss of brinjal fruits. At present, information on the population dynamics of whiteflies locally on brinjal is still lacking. Henceforth, these studies are indeed appropriate to generate a comprehensive understanding on the insect population, which could support an effective pest management programme and crop improvement strategy. The study was conducted at the Field Laboratory of the Faculty of Applied Science, Universiti Teknologi MARA, Shah Alam. The study on the population of whitefly larvae on brinjal plants covered all the plant strata except for the upper stratum. The populations of whitefly were aggregated (Taylor's Power Law Calculate) in first and second cropping of brinjal plants. It may be concluded that the total number of whitefly larvae were found to be most abundant in the middle stratum of the brinjal plants.

“…The developmental time of insect pests may vary with the quality of the host plants and Coudriet et al, (1985) had reported time difference to complete development by B. tabaci. The developmental period is much influenced by the plant texture, metabolites in the sap, plant nutrient status and plant volatiles (Nombela et al, 2000;Mansaray and Sundufu, 2009;Pontes et al, 2010).…”
