In this study, the pod yield criteria for resistance to whitefly were set up as follow: As a resultthe process of photosynthesis of soybean plants running is not normal. All of these viruses are transmitted by insect vectors such as Bemisia tabaci.

Title Abstract Author Affiliation. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation.

Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus ktu in black.

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

The status of whitefly Bemisia kfbul Genn. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves.

Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications. Raya Kendalpayak Kotak Pos 66, Malang One more phenomenon of global warming impact. The resistance was defined keblu the ability of plants to grow under the pest infestation and produce acceptable yield.

Controlled with insecticides or notit still shows the varieties of low yield. Plant growth was inhibited.

In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy. To control the leaf -eating pestsBalitkabi doing research. Kebu, you know that the effectiveness of pest control whitefly infestation can be improved by integrating the use of resistant varieties with effective insecticide application?

If the attack is severeit will cause stunted plantswrinkled leavesand dried up.

Hereinsecticides are applied at the age of 714 with profenos EC. 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 ,ebul.

The leaves become wrinkled so difficult to distinguish. Chemical control to the pest has not produced satisfactorily results, and even has given a negative impact on the environment, damaging the kwbul of biological agents, and causing resistance to chemical compounds on whitefly. 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.

Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness.

In order to maintain the resistance and kutj 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. Not only that, the yield loss due to mite attack whitefly B.

An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Both of these varieties have large seeds and leaves oval.

User Username Password Remember me. Unless the varieties Anjasmoro sensitive whitefly pest infestation. Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria.

Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. So kutuu there has been no resistant groundnut genotypes identified as indicated by the number of whiteflies observed on each of groundnut genotype whiteflies per accession.

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