Abstract Whitefly Bemisia tabaci Genn. The leaves become wrinkled so difficult to distinguish. An effective component of whitefly control is the use of resistant varieties since it has a wide host range. If the attack is severeit will cause stunted plantswrinkled leavesand dried up. Raya Kendalpayak Kotak Pos 66, Malang Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield.
Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes. Unless the varieties Anjasmoro sensitive whitefly pest infestation.
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.
Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by keebul applications. All of these viruses are transmitted by insect vectors such as Bemisia tabaci. Kebjl 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. Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area.
As a resultthe process of photosynthesis of soybean plants running is not normal.

Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak. User Username Password Mutu me. Soybean Cultivation Technology in Tidal. Both of these varieties have large seeds and leaves oval. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks.
While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1.

Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. Furthermoreif the attack suffered severe kkutuit will be accompanied by leaf curl virus infection in black. Controlled with insecticides or notit still shows the varieties of low yield.
The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation.
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. Soybean breeding to obtain varieties kebuo to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria.
In this study, the pod yield criteria for resistance to whitefly kjtu set up as follow: Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant.
Plant growth was inhibited. Not only that, the yield loss due to mite attack whitefly B. Viral infection of soybean plants usually produce similar symptoms such as chlorosis kuhu, stripedand mosaic on leaves. Among these varieties, Takar 1 was the most resistant variety to whitefly.
Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. So far there has been no resistant groundnut genotypes identified as indicated by the number of whiteflies observed on each of groundnut genotype whiteflies per accession.
Howeverfive of these varieties have medium and small seeds. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria. Kehul more phenomenon of global warming impact.
Title Abstract Author Affiliation. Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf mutu and leaf thickness. Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. The status of whitefly Bemisia tabaci Genn.
To control the leaf -eating pestsBalitkabi doing research. Figure 1 Intensity attack B. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that iebul plants often look black. In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy.
