“…Stink bug infestations that occur during ßowering can result in signiÞcant boll injury. Stink bug feeding can cause small bolls to abscise, and reduce yield, lint quality, and seed germination (Barbour et al 1990, Willrich et al 2004a). In nochoice feeding studies, brown stink bug adults and southern green stink bug nymphs reduced seed cotton yield in bolls that accumulated Յ550 heat units (HUs) (Ϸ22 d) and Յ472 HUs (Ϸ21 d) beyond anthesis, respectively (Greene et al 2001, Willrich et al 2004a.…”

Cotton plants were infested with brown stink bug, Euschistus servus (Say), to define cotton boll age classes (based on heat unit accumulation beyond anthesis) that are most frequently injured during each of the initial 5 wk of flowering. Bolls from each week were grouped into discrete age classes and evaluated for the presence of stink bug injury. Brown stink bug injured significantly more bolls of age class B (approximately 165-336 heat units), age class C (approximately 330-504 heat units), and age class D (approximately 495-672 heat units) during the initial 3 wk in both years and in week 5 in 2002 compared with other boll ages. Generally, the frequency of injured bolls was lowest in age class A (< or = 168 heat units) during these periods. The preference by brown stink bug for boll age classes B, C, and D within a week was similar when ages were combined across all 5 wk. Based on these data, bolls that have accumulated 165.2 through 672 heat units beyond anthesis (approximately 7-27-d-old) are more frequently injured by brown stink bug when a range of boll ages are available. The boll ages in our studies corresponded to a boll diameter of 1.161-3.586 cm with a mid-range of 2.375 cm. A general protocol for initiating treatments against stink bugs is to sample bolls for evidence of injury as an indicator of presence of infestations in cotton. Sampling bolls within a defined range, which is most likely to be injured, should improve the precision of this method in detecting economic stink bug infestations in cotton.

“…Jones et al (2000) observed a positive correlation between bolls with seed rot symptoms and the occurrence of hard-locked bolls at boll opening. Barbour et al (1990) determined the proportion of harvestable locules per boll decreased as the duration of infestation and number of punctures per boll by green stink bug, Acrosternum hilare (Say), increased. Although hard-locked bolls were not mentioned in this study, harvestable locks were deÞned as those whose lint was ßuffy and could be collected by simulating a mechanical harvest.…”

“…Stink bugs feed on developing bolls and reduce lint yield and seed quality (Wene and Sheets 1964, Barbour et al 1990, Turnipseed et al 1995, Greene et al 1999, Willrich et al 2003. The contribution of these pests to boll rot and hard-locked bolls will be critical in the development of management strategies.…”

“…Feeding by a complex of boll-feeding bugs, including the green stink bug, Acrosternum hilare (Say), southern green stink bug, Nezara viridula L., and brown stink bug, Euschistus servus (Say), causes substantial economic losses to cotton including boll abscission, lint staining, reduced lint quality, and reduced yields Mention of trade names or commercial products in this publication is solely for providing speciÞc information and does not imply recommendation or endorsement by the University of Georgia or any other organization afÞliated with the authors. (Cassidy and Barber 1939, Toscano and Stern 1976, Barbour et al 1990, Greene et al 1999, Turnipseed et al 2003. Boll feeding is evidenced by rough warty growths on the inner carpel wall and yellow lint staining (Wene and Sheets 1964).…”

Fidelity of External Boll Feeding Lesions to Internal Damage for Assessing Stink Bug Damage in Cotton

Previous research showed that the most precise estimates of stink bug damage in developing cotton bolls are obtained by collecting soft quarter-sized bolls and dissecting them for signs of internal feeding damage, such as internal boll wall warts and/or stained lint. However, this method requires considerable time and effort; therefore, scouts and growers are unwilling to invest adequate resources to make sound pest management decisions. Here, the authors evaluated enumeration of external feeding lesions on groups of 10, 15, 20, or 25 bolls per sample as an alternative sampling procedure. Results relate the similarity of external boll feeding lesions to internal damage as a function of boll sample size and external lesion tally. Inverse prediction confidence intervals (CIs) were also calculated to predict internal boll damage on a new sample based only on external feeding lesions. Results show that linear regression model fit increased when examining at least 20 bolls per sample, and only one external lesion per boll provided as good of model fit as using a minimum of two, three, or four lesions per boll. Inverse prediction CIs suggested that more than one sample (20 bolls per sample) will be required to make external lesions an acceptable method for making reasonably accurate management decisions. F-test lack of fit and significant regression models suggest that examination of external lesions is a promising a method for estimating stink bug damage in cotton.
