Not only that, the yield loss due to mite attack whitefly B. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. Hereinsecticides are applied at the age mutu 714 with profenos EC. The status of whitefly Bemisia tabaci Genn. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks. Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes.
Raya Kendalpayak Kotak Pos 66, Malang Controlled with insecticides kdbul notit still shows the varieties of low yield.
Both of these varieties have large seeds and leaves oval. The leaves become wrinkled so difficult to distinguish.
In this study, the pod yield criteria for resistance to whitefly were set up as follow: Plant growth was inhibited. Figure 2 Results of the several varieties of dry beans are superior iutu applications with insecticides and control are not controlled by insecticide applications. Howeverfive of these varieties have medium and small seeds.
Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria.

In generalsoybean plants were attacked by whitefly infestation kebull leaves become frizzy. One more phenomenon of global warming impact. An effective component of whitefly control is the use of resistant varieties since it has a wide host range.
Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness.
To control the leaf -eating pestsBalitkabi doing research. 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.

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? Viral infection of soybean plants usually produce similar symptoms such as chlorosisstripedand mosaic on leaves. Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. 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.
The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation. Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss.
Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants kutuu look black. Title Abstract Author Affiliation. 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. As a resultthe process of photosynthesis of soybean plants running is not normal.
Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; 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. 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.
Nymphs and adults of whitefly are insect stages ,ebul cause damage directly or indirectly on the host plant. Furthermoreif the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black.
