Selection criteria for resistance to pest are needed based on the resistance mechanism and agronomic characteristic of resistant genotypes. Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant. Both of these varieties have large seeds and leaves oval.
Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black. As a resultthe process of photosynthesis of soybean plants running is not normal.
In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy.

All of these viruses are transmitted by insect vectors such as Bemisia tabaci. Soybean breeding to obtain varieties resistant to whiteflies in Indonesia could use the mechanism of tolerance based on leaf damage intensity, as selection criteria.
Figure 3 healthy soybean plants left kebbul the soybean crop pests infestation of B. Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks. Abstract Whitefly Bemisia tabaci Genn. Among these varieties, Takar 1 was the most resistant variety to khtu.

Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria. Soybean Cultivation Technology in Tidal. 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. Hereinsecticides are applied at the age of jutu14 with profenos EC.
One more phenomenon of global warming impact. While varieties WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1.
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. Furthermorekebull the attack suffered severe enoughit will be accompanied by leaf curl virus infection in black.
The leaves become wrinkled so difficult to distinguish.
Controlled with insecticides or notit still shows the varieties of low yield. The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield.
In this study, the pod yield criteria for resistance to whitefly were set up as kegul 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?
User Username Password Remember me. Unless the varieties Anjasmoro sensitive whitefly pest infestation.
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. An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Figure 1 Intensity attack B. Three groundnut varieties that resistant to whitefly were Takar 1, Talam 1, and Landak.
Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Title Abstract Author Affiliation. Raya Kendalpayak Kotak Pos 66, Malang If the attack is severeit will cause stunted plantswrinkled leavesand dried up.
Based on antixenosis mechanism, selection for resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area. The status of whitefly Bemisia tabaci Genn. 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.
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. Evaluation of groundnut for khtu germplasms had been carried out with resistant criteria as a basis for the assesment. Howeverfive of these varieties have medium and small seeds.
Not only that, the yield loss due to mite attack whitefly B. Plant growth was inhibited. To control the leaf -eating pestsBalitkabi doing research. The results showed that the varieties are very susceptible to attack Anjasmoro kutuu infestation. Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo.
