“…Resistance information of soybean genotypes to the whiteflies is important to be known by soybean breeders as a guide in selecting source of resistance genes to be used in the improvement of soybean varieties resistant to whiteflies. There are several methods to determine the resistance of soybean genotypes to the whiteflies, among others, by counting the number of population of whiteflies (eggs, larvae, and pupae) per leaf (Gulluoglu et al 2010b), or the number of nymphs per leaf (Xu et al 2005;Amro et al 2007;Xu et al 2009;Xu 2009), and based on the intensity of leaf damage due to the attack of whiteflies (Inayati and Marwoto 2012;Taggar et al 2013). The success of the utilization of soybean genotypes that resistant to whiteflies has been reported by researchers in Turkey (Gulluoglu et al 2010b).…”

Sulistyo A, Inayati A. 2016. Mechanisms of antixenosis, antibiosis, and tolerance of fourteen soybean genotypes in response to whiteflies (Bemisia tabaci). Biodiversitas 17: 447-453. The attack of whiteflies (Bemisia tabaci) in soybean cultivation in Indonesia is one of the limiting factors in increasing the national soybean production. Planting resistant varieties could reduce yield losses due to the damage caused by these pests. This study was conducted to evaluate the resistance of 14 soybean genotypes to the whiteflies. A free- choice and no-choice test was conducted in a green house to study the antixenosis and antibiosis. Meanwhile, field evaluation was conducted to determine the tolerance of soybean genotypes to the whiteflies. Determination of the resistance of soybean genotypes to whiteflies based on the intensity of leaf damage that occurs on fifth weeks after infestation. The results showed that in free-choice test, Gema, IAC-100/Kaba-6, Malabar/IAC-100-85, Kaba/IAC-100//Burangrang-60, and Kaba/IAC-100//Burangrang-63 showed antixenosis mechanism which correlates with length and low density of leaf trichomes as well as leaf thickness. In the no-choice test, antibiosis mechanism can be seen from the small number of adults that develop from nymphs. IAC-100/Kaba-8 and IAC-100/Kaba-14 showed a high degree of antibiosis. In addition, the results of field experiment showed that Gema, IAC-100/Kaba-14, and Tanggamus/Pangrango- 78 demonstrated a tolerance to whiteflies. It is shown on a slightly decreasing in yield of these three genotypes (17.33, 19.31, and 19.85%, respectively).

The increasing and stabilizing of soybean product in Indonesia face many limitations. One of the limiting factors is pod borrer (Etiella zinckenella Treitschke) infestation that is able to cause yield loss up to 80%. Objective of the research was to find out some advanced soybean lines that resistant to pod borrer. Design was randomized complete block with three replications. Soybean lines were grown gradualy to ensure the simultanously flowering. The plants were caged at 35 days after planting (DAT) and infested with the imago of E. zinckenella at 56 DAT. Results showed that different soybean lines affected imago population, eggs population, larvae population, infected pods and infected seeds. Some genotypes were consistantly resistant to E. zinckenella. The resistance of those genotypes were non preference resistance based on eggs population, larvae population, infected pod and infected seeds. This study discovered nine soybean lines that is resistant to E. zinckenella, so that it can be beneficial for improving soybean resistance to this pest through releasing as a new resistant pod borer variety after tested further in potential yield and genetic x environment interaction trials. In addition, there were three varieties and two germplasm accessions that can be used as gene sources for improving the resistance of the varieties. The three varieties are able to be cultivated directly in field to decrease the E. zinckenella occurrence. Soybean variety "Wilis" was grown sequentially in ILETRI's greenhouse with one week interval for seven times planting date in the area of 7 m x 5 m every planting date. Plants were fertilized using Urea 0.4 g/hill and NPK 1.2 g/hill. Bean fly pests were controlled with insecticides of cypermethrin on 8 DAP, and leaf pests were controlled with insecticides of cyhalothrin at 14, 21, and 28 days after planting. After the plant was 28 DAP, controls were carried out manually. How to CitePod borer insects were obtain from collecting of instar 5 larva in Ngale Research Station, Ngawi Regency, East Java Province, Indonesia. The collected larva were taken to ILETRI's pest laboratory. Larva were reared in the plastic container, where in the container was filled with sawdust. Larvae were reared until transforming to be pupae and then the pupae moved to copulation cage. At the top of the inside cage, there were hanging cotton layer filled with 10% honey solution for feeding the imago that out from the pupa. At three days after the imago appeared, imago was identified for the sex, and the damages of foot and antene by using binocullar microscop. At four days age, the selected imagos were ready to be applied in treatment plants.Planting was conducted in RCBD with three replications, where every replication consisted of 6 polybags/genotype with four seeds/ polybag. Planting was conducted based on flowering age of each genotype in order pod setting start simultaneously. Fertilizers were applied by using Urea 0.4 g and NPK 1.2 g per polybag at sowing date. Watering were carried out by monit...

Pod borer is a major pest on soybean. The objective of this study was to determine the resistance of soybean genotypes against pod borer based on choice test. The experiment was conducted in green house and laboratory of Entomology, Indonesian Legumes and Tuber Crops Research Institute, using Randomized Block Design with 16 soybean genotypes and three replicates. Planting dates was arranged such a way so as to sincronize the flowering time and pod formation of 16 soybean genotypes. A pairs of 4 days emerged adult pod borer were infested into each plant at R4 stage (21 days after flowering) for two days. The number of egg was observed at 2 days after infestation (DAI) and the number of larva and damaged intensity were observed at 14 DAI. The results showed that genotypes significantly affected egg and larval population, pod and seed damage intensity. The lowest egg and larval population found on Anjasmoro, 6,33 eggs and 10 individuals, respectively. The lowest intensity of pod damage found on Anjasmoro (27,74%), and the lowest intensity of seed damage found on Malabar/Sinabung-68 (15,61%). The resistance of soybean genotypes was non-preference as place to lay eggs and as feed. In conclusion, there were two genotypes showed consistently resistant (Anjasmoro and Malabar/Sinabung-68). These genotypes could be used as a source of genes for varietal improvement of soybean resistance against pod borer.
