Controlled with insecticides or notit still shows the varieties of low yield.

Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications. Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for kebu, assesment.

Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black. In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy.

Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness. Not only that, the yield loss due to mite attack whitefly B. The leaves become wrinkled so difficult to distinguish. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks. Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black.

Raya Kendalpayak Kotak Pos 66, Malang kut Severe pest attacks occurred in the hot and dry kebl caused significant groundnut yield loss. 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. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation. In addition to directly damaging cropsiebul a whitefly infestation of insect vectors that can transmit disease kevul Cowpea mild mottle virus CMMV on soybeans and other legumes.


Figure 1 Intensity attack B. Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant. 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.

Unless the varieties Anjasmoro sensitive whitefly pest infestation. Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. One more phenomenon of global warming impact.

To control the leaf -eating pestsBalitkabi doing research. The status of whitefly Bemisia tabaci Genn. 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.

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. Howeverfive of these varieties have medium and small seeds. Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes.


In this study, the pod yield criteria for resistance to whitefly were set up as follow: Both of these varieties have large seeds and leaves oval. While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria. Plant growth was inhibited.


Among these varieties, Takar 1 was the most resistant variety to whitefly. ,ebul 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.

Abstract Whitefly Bemisia tabaci Genn. The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield.

Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves. Soybean Cultivation Technology in Tidal. If the attack is severeit will cause stunted plantswrinkled leavesand dried up.

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

Kjtu additionsubsequent varieties are sensitive enough Argomulyo. 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? All of these viruses are transmitted by insect vectors such as Bemisia tabaci. An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Title Abstract Author Affiliation. Hereinsecticides are applied at the age of 714 with profenos EC.
