If the attack is severeit will kutk stunted plantswrinkled leavesand dried ksbul. To control the leaf -eating pestsBalitkabi doing research. In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy. Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications.

Among these varieties, Takar 1 was the most resistant variety to whitefly. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria. Plant growth was inhibited. 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.

Kugu 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.

An effective component of whitefly control is the use of resistant mebul since it has a wide host range. Controlled with insecticides or notit still shows the varieties of low yield. Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation ksbul, nymphs, pupas, adults per leaf area. One more phenomenon of global warming impact. 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.

Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant.

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.

Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves. Figure 1 Intensity attack B. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black.

Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. Howeverfive of these varieties have medium and small seeds.

While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1. In this study, the pod yield criteria for resistance to whitefly were set up as follow: Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak. Not only that, the yield loss due to mite attack whitefly B.

Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation. The status of whitefly Bemisia tabaci Genn.

Title Abstract Author Affiliation. All of these viruses are transmitted by insect vectors such as Bemisia tabaci.

Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks. 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?

Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria.

As a resultthe process of photosynthesis of soybean plants running is not normal. Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black. The leaves become wrinkled so difficult to distinguish.
