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. Worse yetthis whitefly infestation excreta produce honey dew which is a sooty fungus growing mediumso that the plants often look black.
Raya Kendalpayak Kotak Pos 66, Malang Not only that, the yield loss kuth to mite attack whitefly B. The results showed that the varieties are very susceptible to attack Anjasmoro whitefly infestation.
In this study, the pod yield criteria for resistance to whitefly kdbul set up as follow: Nymphs and adults of whitefly are insect stages that cause damage directly or indirectly on the host plant. Howeverfive of these varieties have medium and small seeds. Title Abstract Author Affiliation.
An effective component of whitefly control is the use of resistant varieties since it has a wide host range. Evaluation of groundnut for resistant germplasms had been carried out with resistant criteria as a basis for the assesment.
Hereinsecticides are applied at the age of 714 with profenos EC. 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?
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. Soybean resistant mechanism to whitefly could be through physical antixenosis, such as through the leaf trichomes and leaf thickness.
Abstract Whitefly Bemisia tabaci Genn. The leaves become wrinkled so difficult to distinguish. Keywords Soybean; whitefly; antixenosis; antibiosis; tolerance; selection criteria. iebul
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. While ekbul WilisKabaGepak yellowand Gepak Ijo including varieties that are tolerant to whitefly infestation attack Figure 1.
Anjasmoro additionsubsequent varieties are sensitive enough Argomulyo. Both of these varieties have large seeds and leaves oval.
User Username Password Remember me. Selection of resistant soybean based on tolerance mechanisms was done by observing the decrease in grain yield due to whitefly attacks.
Kuty 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. Unless the varieties Anjasmoro sensitive whitefly pest infestation.
Severe pest attacks occurred in the hot and dry season caused significant groundnut yield loss. Figure 1 Intensity attack B.

In generalsoybean plants were attacked by whitefly infestation the leaves become frizzy. One more phenomenon of global warming impact.
Based on antixenosis mechanism, selection kuyu resistance is done by counting the number of whitefly infestation eggs, nymphs, pupas, adults per leaf area.
The status of whitefly Bemisia tabaci Genn. All of these viruses are transmitted by insect vectors such as Bemisia tabaci.
Among these varieties, Takar kutk was the most resistant variety to whitefly.

Plant growth was inhibited. Figure 2 Results of the several varieties of dry beans are superior in applications with insecticides and control are not controlled by insecticide applications. 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.
The resistance was defined as the ability of plants to grow under the pest infestation and produce acceptable yield.
