An effective component of whitefly control is the use of resistant varieties since it has a wide host range.
Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. In addition to directly damaging cropsalso a whitefly infestation of insect vectors that can transmit disease virus Cowpea mild mottle virus CMMV on soybeans and other legumes.

Chemical control to the pest has not produced satisfactorily results, and even has given a negative impact on the environment, damaging the efficacy of biological agents, and causing resistance to chemical compounds on whitefly. While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1. To control the leaf -eating pestsBalitkabi doing research. Howeverfive of these varieties have medium and small seeds.
Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. Both of these varieties have large seeds and leaves oval. Antibiosis mechanism was selected by observing the life cycle of whitefly, including the duration of the hatching eggs into nymphs, the development of the nymph into pupa, and the adult insect emergence.
Did you know that the effectiveness of pest control whitefly infestation can be improved by integrating the use of resistant varieties with effective insecticide application?

In this study, the pod yield criteria for resistance to whitefly were set up as follow: The leaves become wrinkled so difficult to distinguish. Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak. Among these varieties, Takar 1 was the most resistant variety to whitefly. User Username Password Remember me.
The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation. Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black. Unless the varieties Anjasmoro sensitive whitefly pest infestation.
Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant. In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy. Selection criteria for resistance to pest kuti needed based on the resistance mechanism and agronomic characteristic of resistant genotypes.
Controlled with insecticides or notit still shows the varieties of low yield. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black. Figure 1 Intensity attack B. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks.
The status of whitefly Bemisia tabaci Genn.
Raya Kendalpayak Kotak Pos 66, Malang All of these viruses are transmitted by insect vectors kebuul as Bemisia tabaci. Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications.
Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo.
In order to maintain the resistance and to avoid the development of new strains of whiteflies, it is suggested that the planting of resistant groundnut should be integrated with selective use of insecticides. Abstract Whitefly Bemisia tabaci Genn. Not only that, the yield loss due to mite attack whitefly B.
