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

Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Both of these varieties have large seeds and leaves oval. Abstract Whitefly Bemisia tabaci Genn. Raya Kendalpayak Kotak Pos 66, Malang Figure 1 Intensity attack B.
All of these viruses are transmitted by insect vectors such as Bemisia tabaci. In this study, the pod yield criteria for resistance to whitefly were set up as follow: Plant growth was inhibited. While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1.
Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant. The leaves become wrinkled so difficult to distinguish. 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.
Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment. 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? 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.
Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications. One more phenomenon of global warming impact. 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.
Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. However kebyl, five of these varieties have medium and small seeds. Title Abstract Author Affiliation. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black. The status of whitefly Bemisia tabaci Genn.
Unless the varieties Anjasmoro sensitive whitefly pest infestation.
In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy. The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield. Among these varieties, Takar 1 was the most resistant variety to whitefly. An effective component of whitefly control is the use of resistant varieties since it has a wide host range. 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 kebuul use of insecticides.
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. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria.

Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness. 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.
Figure 3 healthy soybean plants left and the soybean crop pests infestation of B. User Username Password Remember me.
To control the leaf -eating pestsBalitkabi doing kegul.
As a resultthe process of photosynthesis of soybean plants running is not normal. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation.
Hereinsecticides are applied at the age of 714 with profenos EC.
