Hereinsecticides are applied at the age of 714 with profenos EC. 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. Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant.

An effective component of whitefly control is the use of resistant varieties since it has a wide host range. In this study, the pod yield criteria for resistance to whitefly were set up as follow: Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks.

Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. If the attack is severeit will cause stunted plantswrinkled leavesand dried up. Unless the varieties Anjasmoro sensitive whitefly pest infestation. 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.

In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy. 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. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria.

Controlled with insecticides or notit still shows the varieties of low yield. Soybean Cultivation Technology in Tidal. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria.

Howeverfive of these varieties have medium and small seeds. Among these varieties, Takar 1 was the most resistant variety to whitefly.

Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak. Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes.

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 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.

All of these viruses are transmitted by insect vectors such as Bemisia tabaci. Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves.

Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield. So far there has been no kkebul groundnut genotypes identified as indicated by the number of whiteflies observed on each of groundnut genotype whiteflies per accession.

Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. The leaves become wrinkled so difficult to distinguish. Not only that, the yield loss due to mite attack whitefly B. One more phenomenon of global warming impact. ,ebul 1 Intensity attack B. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation.

As a resultthe process of photosynthesis of soybean plants running is not normal.
