“…However, soybeans planted in the conventional system experience higher populations later in the season, and those populations are much higher than the populations that occur on the earlier planted soybeans (McPherson et al 2001). Those results were consistent with results from other states throughout the southern United States (Baur et al 2000). Overall, stink bug pressure is greatly reduced when early maturing soybean varieties are planted early compared with a conventional soybean system.…”

“…An added bonus is that these early production systems may also escape injury from some insect pests. In the southern United States, beneÞts of the early soybean production system have been observed for velvetbean caterpillar, Anticarsia gemmatalis Hü bner; soybean looper, Pseudoplusia includens (Walker); three cornered alfalfa hopper, Spissistilus festinus (Say); and stink bugs (Baur et al 2000, McPherson et al 2001. Overall, insect pest populations were lower on maturity group IV soybeans planted early than on maturity group V, VI, and VII soybeans planted at normal planting dates.…”

“…The dynamics of these insects coincided with the period of suitability of the host for their feeding (Wada et al 2006). The populations were generally low early in the season and increased as the season progressed, which was consistent with the reports by other workers (Jackai and Singh 1987;McPherson 1996;Baur et al 2000;Bundy and McPherson 2000;Anyim 2003;Smith et al 2009). This population buildup over the season was probably due to more suitable temperatures and relative humidity that favour insect multiplication as the season progressed (Talekar and Chen 1983;Kamara et al 2010).…”

Insecticide protection at the vegetative, reproductive or both vegetative and reproductive (complete) crop growth stages and untreated control was used to assess yield loss due to insect pests at the different growth stages of soybean in Ghana from 2007-2009. The objectives were to determine the economic importance of the two major insect pest guilds in soybean, viz. defoliators and pod feeders, and when to apply control measures for maximum benefit. The defoliators recorded were Podagrica spp., Ootheca mutabilis (Shalberg), Zonocerus variegatus L., Sylepta derogata F., Spodoptera littoralis Boisduval, Amsacta spp. and Helicoverpa armigera Hu¨bner. The pod feeders recorded were the pod-sucking bugs (PSBs) Riptortus dentipes F., Thyanta sp. Aspavia armigera F., Nezara viridula L. and Dysdercus vo¨lkeri Schmidt. Generally, insect densities, pod and seed damage were lower while seed yields were significantly greater and similar in plots that were protected at the reproductive stage against PSBs and those protected at both vegetative and reproductive stages. Yield loss ranged between 25.8 and 42.8% in untreated plots, 11.1 and 34.3% in plots that were protected at the vegetative stage, and 5.2 and 11.3% in plots that were protected at the reproductive stage. There was a consistent negative correlation between yield and numbers of PSBs as well as pod and seed damage. These results showed that PSBs that attack soybean at the reproductive stage were the most important insect pests limiting soybean yield in Ghana.

“…Furthermore, uniform delayed planting was recommended in the rolling plains of Texas to manage boll weevil in cotton based on the beetleÕs diapause and overwintering survival (Slosser 1978). Soybean cultivars that allowed early planting in the mid-South had fewer lepidopteran defoliators but harbored more stink bugs (Baur et al 2000).…”

Influence of Planting Date on Stink Bug Injury, Yield, Fiber Quality, and Economic Returns in Georgia Cotton

2014

Phytophagous stink bugs are economically important pests of annual and perennial crops in the southeastern United States. Because of insecticide resistance and risk of secondary pest outbreaks, there is interest in identifying cultural practices that could lead to reduced insecticide applications. The objective of this project was to assess the importance of cotton planting date on stink bug damage to cotton. Unsprayed cotton plots with biweekly planting dates were established at three locations in southern Georgia in each of two crop years. During the bloom cycle, stink bug-induced boll injury was estimated weekly in each plot. Plots were subsequently defoliated, mechanically harvested, and ginned to assess differences in fiber yield and quality attributable to stink bug injury. Results show that the rate of boll damage generally increased more rapidly through the bloom cycle for planting dates in June compared with May. Similarly, estimates of boll damage from June-planted cotton more frequently exceeded the stink bug treatment threshold compared with May-planted cotton. In 2011, mean lint yield and economic returns from May planting dates were significantly greater than June planting dates. In 2012, lint yield and economic returns were greater in plots established in early May compared with later planting dates. Estimates of HVI color + b, a measure of fiber yellowness, were lower in early May-planted cotton compared with June planting. These data show that growers need to be aware of increased stink bug damage potential when planting late.
