“…In the second environment (SP, sprayed), the population of B. tabaci at 20 DAP was 1.65 adults per plant, reaching the peak population at 40 DAP (22.57 adults/plant), after which the population declined at 60 DAP (9.60 adults/plant) (Figure 1B). In other studies, B. tabaci infestations also showed variability among genotypes (Murry et al 2018;Kumar et al 2019). tabaci population in the NS environment was 110.33 to 154.17 adults/plant, while that in the SP environment was 11.00-45.75 adults/plant.…”

“…Highly resistant and susceptible genotypes were not found in NS or SP environments. However, other studies have found that soybeans resistant to B. tabaci ranges from highly susceptible to highly resistance (Gulluoglu et al 2010;Cruz & Baldin 2016;Murry et al 2018). Each genotype has a unique mechanism of resistance to whiteflies.…”

Whiteflies are a severe threat to soybean production in the tropics. This study aimed to evaluate the soybean resistance level of the whitefly Bemisia tabaci in controlled and uncontrolled environments that is associated with plant age, damage intensity, and trichome density. The research was conducted under two conditions: non-sprayed (NS) and sprayed (SP). This study used 50 soybean genotypes arranged in a randomized block design with three replicates. The whitefly population was derived from natural infestations. The results showed that the highest wild population of B. tabaci occurred at 40 days after planting (DAP), i.e., 126.08 adults/plant in the NS environment and 22.57 adults/plant in the SP environment. The peak damage intensity occurred at 50 DAP, 20.71% in the NS environment, and 17.15% in the SP environment. In the NS environment, there were six resistant genotypes (including the resistant control G100H), 25 moderate, and 19 susceptible genotypes. In the SP environment, 19 genotypes were resistant, 22 genotypes were moderate, and nine genotypes were susceptible, respectively. Six soybean genotypes showed consistent resistance to B. tabaci in NS and SP environments. The low density of leaf trichomes in soybean may influence the high resistance to B. tabaci. The resistant genotypes identified in this study could be utilized in breeding programs for B. tabaci resistance.

“…In India, the major insect pests observed were whitefly (Aleurodicus dispersus), leaf webber (Anarsia ephippias), flea beetle (Systena sp. ), and stink bug (N. viridula) [4]. In Indonesia, the most common soybean pod-sucking pests are N. viridula and R. linearis [5 -7].…”

Background: The southern green stink bug (SGSB), Nezara viridula, is a potentially harmful pod sucker insect found in soybean. Objective: The objective of this study was to evaluate the resistance level of several soybean advanced breeding lines against the southern green stink bug N. viridula under the free-choice and no-choice tests. Methods: The research materials were 14 advanced breeding lines and four check cultivars. The experiment was conducted in Malang, East Java, Indonesia, during the dry season I and II 2022. The resistance evaluation of the soybean genotypes against the N. viridula was under the Free-Choice test (FC) and the No-Choice test (NC). The newly emerged adults N. viridula were infested when plants reached the R5 stage. The data were observed for damage intensity, yield and yield components. Results: The intensity of pod damage in the FC ranged from 20.09 to 46.40%, meanwhile, in the NC was 25.63 to 67.63%. This shows that the NC condition provides more selection pressure than the FC. Each genotype exhibited different resistance reactions in the FC and NC. The pod damage intensity had a significant negative correlation with seed yield both in the FC and NC. Conclusion: The No-Choice test (NC) provided a higher selection pressure for resistance to SGSB than the Free-Choice test (NC). The use of SGSB-resistant cultivars will prevent soybean seed yield losses. A new finding in this study, two soybean genotypes Anj/Rjbs-305 and Anj/Rjbs-306 were resistant to SGSB. Both genotypes exhibit good agronomic performance (high yield and large seed size), thus can be proposed as new soybean varieties to be developed in the country.
