Compared to other stink bugs attacking soybean, this pest is less susceptible to insecticides commonly used on soybean for stink bug control [ 9 , 10 ]. On each sampling date, soybean growth stages for each MG were recorded based on descriptions by Fehr et al. Some of these species have less extensive geographic ranges and do not occur in all parts of the midwestern United States e. Thirty plants per location per week were randomly removed from each MG. This study reported that the average number of eggs were Specifically, data on growth stage, plant height cm , number of nodes per plant, oviposition site leaf [abaxial or adaxial], pod, or stem , main stem node of oviposition site, and number of eggs per cluster mass were recorded.
The redbanded stink bug is a neotropical stink bug species that ranges from Argentina north to the Southern United States [ 2 ]. Based primarily on information from southern states, scouting, thresholds, and insecticide-based management of these pests are discussed. The biologies and impacts of stink bugs to crops are discussed, with particular attention to differences among species. Plant heights were different between MG; A total of redbanded stink bug eggs in egg masses clusters were field collected from naturally-occurring populations in MG IV and V soybean over a three year period to Based on position within the vertical plant strata, egg clusters were further categorized as being in the upper, middle, or lower plant canopy. The mean number of eggs within a cluster was Sampling for redbanded stink bug eggs was initiated at the R2 full flower stage and continued weekly until R7 beginning maturity. Whole plants were destructively sampled and examined for the presence of redbanded stink bug egg clusters. The ratio of females to males was similar in all soybean growth stages except R5, where the sex ratio increased to 1. At least 24 species or subspecies of stink bugs could potentially be encountered in soybean and corn in the midwestern United States Table 1. Studies on nymphal development and survivorship, adult longevity and reproduction, and life stage dispersal on South American soybean have provided considerable information on the biology and ecology of the redbanded stink bug [ 5 ]. Within a MG, plant heights differed by growth stage Table 1. The redbanded stink bug is a significant annual pest in South American soybean, especially in Brazil [ 3 ]. The midwestern United States is the top Glycine max L. In this region, particularly in the more northern states, stink bugs have historically caused only infrequent impacts to these crops. On each sampling date, the soybean growth stages for each MG were recorded. Each MG was divided into six sub-plots. The redbanded stink bug has also shown a propensity to develop high infestations five-fold action threshold within soybean fields over a relatively brief period [ 1 ]. Introduction Several phytophagous stink bugs including green stink bug, Chinavia hilaris Say , southern green stink bug, Nezara viridula L. The number of eggs within a cluster ranged from 2 to Though having been previously reported on soybean in the United States, it was not considered an economic pest [ 4 ]. Samples of redbanded stink bug adults were segregated and sex was determined based on diagnostic keys [ 3 ]. The significance of stink bugs in the midwestern United States is increasing. As populations of this species increase in the midwestern United States, increasing frequencies of economically significant infestations are likely. Abstract Redbanded stink bug, Piezodorus guildinii Westwood , is a significant soybean pest across the mid-south region of the United States.

Oviposition Replies A modest of 5, redbanded flirt bug eggs in egg means were sampled and used over three times.
