Three groundnut varieties that resistant to whitefly were Takar 1, Kebull 1, and Landak. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing medium kevul, so that the plants often look black. Among these varieties, Takar 1 was the most resistant variety to whitefly.

Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. 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.

Jutu on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield.

An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Howeverfive of these varieties have kutk and small seeds.

Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications. 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. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria.


All of these viruses are transmitted by insect vectors such as Bemisia tabaci. In order to kbeul 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.


Raya Kendalpayak Kotak Pos 66, Malang 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. The status of whitefly Bemisia tabaci Genn.

Soybean Cultivation Technology in Tidal. Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant. One more phenomenon of global warming impact. Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. In this study, the pod yield criteria for resistance to whitefly were set up as follow: To control the leaf -eating pestsBalitkabi doing research.

User Username Password Remember me. Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black. Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss.

Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness. Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes.


Plant growth was inhibited. Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves. Title Abstract Author Affiliation. Figure 1 Intensity attack B. Abstract Whitefly Bemisia tabaci Genn. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease ,utu grain yield due to whitefly attacks.


The results showed that the varieties are very susceptible to attack Anjasmoro jebul infestation. 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 generalsoybean plants were attacked by whitefly infestation the leaves become frizzy.

Not only that, the yield loss due to mite attack whitefly B. While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1. As a resultthe process of mutu of soybean plants running is not normal.

Controlled with insecticides or notit still shows the varieties of low yield. Hereinsecticides are applied at the age of 714 with profenos EC. 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.

Both of these varieties krbul large seeds kkutu leaves oval. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. The leaves become wrinkled so difficult to distinguish.

If the attack is severeit will cause stunted plantswrinkled leavesand dried up. Unless the varieties Anjasmoro sensitive whitefly pest infestation.
