“…Similar findings were reported in Nigeria by Jackai et al (1988). Pod-sucking bugs' attack to pods result in pod and seed abscission as well as seed shrivelling and decay (Jackai and Singh 1987;Gore et al 2006). Plants may have enough time to compensate for early season insects' attack by defoliators.…”

“…However, the compensatory ability is limited during the reproductive stage, such as during podding due to senescence (Hunt et al 2010). Gore et al (2006) observed that early sown soybean escaped peak PSB populations and damage during podding. Also, Sastawa et al (2004) reported that early sown soybean recovered from insect defoliation and/or compensated for pod damage to produce high grain yield.…”

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.

“…The overwintering population of E. servus becomes active during late March and early April, before feeding on wild hosts or early agronomic hosts such as wheat (Triticum aestivum L.), and these adults then produce the Þrst generation of nymphs from May to July (Jones andSullivan 1981, 1982;Munyaneza and McPherson 1994;Reay-Jones 2010). Previous studies and this study indicate that the number of adults in agronomic hosts throughout the summer is relatively low, but there is a sharp increase in the number of E. servus adults during late September and October; these new adults do not sexually mature, but go on to overwinter (Bundy and McPherson 2000;Gore et al 2006;Smith et al 2009a,b).…”

Seasonal Abundance and Population Structure of Brown Stink Bug (Hemiptera: Pentatomidae) in Farmscapes Containing Corn, Cotton, Peanut, and Soybean

Stink bugs are economically important pests of food and fiber production throughout the southeastern United States. In cotton, stink bugs feed on developing bolls thereby decreasing yield and fiber quality. The brown stink bug, Euschistus servus (Say) (Hemiptera: Pentatomidae), is a common species that is found throughout the southeast and feeds on a variety of wild and agronomic hosts. In this study, the population dynamics and reproductive biology of E. servus were assessed in 1.62–2.83-ha farmscapes planted with corn (Zea mays L.), cotton (Gossypium hirsutum L.), peanut (Arachis hypogaea L.), and soybean [Glycine max (L.) Merr.]. Farmscapes were sampled weekly using whole plant sampling for corn and sweep net sampling in cotton, peanut, and soybean. In 2010, but not 2009, nymphs were classified by instar, and adults were dissected to rate gonads as nonrepro-ductive, intermediate, or reproductive. Regardless of year, stink bugs observed in corn during the spring and early summer and were a mixture of all three reproductive stages. The number of E. servus nymphs and adults was low in all crops during the summer (July, August, and early September). In late September, the number of fifth instars rose sharply followed by an increase in the number of nonreproductive adults, which implies that these adults resulted from reproduction as opposed to immigration. Incidence of late instars and nonreproductive adults was extremely low for corn, cotton, and peanut, and these host plants did not seem to be highly suitable reproductive hosts. Results from this study are useful for pest management programs that focus on reducing stink bug populations on a landscape scale.

“…Average total soybean losses and control costs because of insects in the southern United States in 2011 ranged from US$28.50/ha in Alabama to US$216.87/ha in Arkansas (Musser et al 2012). A complex of stink bug (Hemiptera: Pentatomidae) species, most notably Nezara viridula (L.), Euschistus servus (Say), and Chinavia hilaris (Say), feed on soybean pods and seeds, reducing seed yield and quality (Gore et al 2006. Stink bugs are commonly managed with pyrethroid insecticides (Kamminga et al 2009), which have shown high efÞcacy against M. cribraria in Þeld trials (unpublished data).…”

Reduction of Soybean Yield Components by <I>Megacopta cribraria</I> (Hemiptera: Plataspidae)

Since its discovery in the United States, the invasive plataspid Megacopta cribraria (F.) (Hemiptera: Plataspidae) has infested soybean [Glycine max (L.) Merrill] fields in often alarming numbers in parts of the southeastern United States. Although a known feeder on soybean, reports of its pest status in its native Asian range are conflicting, and little information exists documenting its impact on soybean yields. Our objective was to examine the relationship between M. cribraria density and soybean yield loss. M. cribraria adults and nymphs were confined to small soybean plots by using walk-in field cages from late vegetative stage to harvest in 2011 and 2012. Adults (0, 5, or 25 per plant) were added at late vegetative stages, and their progeny were allowed to complete a full generation within the caged plots. Densities reached as high as 182.5 +/- 23.1 (SEM) nymphs and adults per plant, and soybean yield was reduced by as much as 59.6% at the highest density treatment. The yield components seeds per pod and individual seed weight were reduced as M. cribraria densities increased, but pods per plant and protein and oil content were not affected. Preliminary economic injury level curves for a range of grain prices and management costs were calculated based on 2012 yield loss data combined with population monitoring. M. cribraria is capable of causing severe reductions in soybean yields at densities that are relevant within its invasive U.S. range.
