“…Boll weevils are differentially attracted to plant volatiles, leaf color, and gossypol content among races of G. hirsutum (McKibben et al 1977, Hedin and McCarty 1995, Allen 2008. It is possible that local populations have adapted to characteristics of speciÞc hosts and may be preferentially attracted to local cotton species for feeding and oviposition.…”

“…The Swedish entomologist C. H. Boheman described A. grandis grandis in 1843 from a specimen collected in Veracruz, Mexico. The insect crossed the Rio Grande in 1892 and quickly moved through the Cotton Belt in the southeastern United States (Burke et al 1986, Allen 2008. This range expansion is believed to have been a result of increased cotton production in northeastern Mexico after the devastation of the cotton-growing industry in the United States during the Civil War (Jones 2006, Allen 2008).…”

“…An increase in cotton agriculture in northern Mexico bridged a geographical gap for boll weevil migration and establishment in areas previously devoid of a host for the pest. This resulted in ruinous consequences for U.S. cotton production including ϾUS$10 billion in crop damage and management costs within the United States alone (Allen 2008). Although the boll weevil has recently been eradicated from much of the southeastern United States and parts of northern Mexico, many areas continue to be active eradication zones in which management and associated costs are signiÞcant (Allen 2008).…”

Although the boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is a devastating pest in the United States and Mexico, its population structure and genetic diversity in Mexico on wild and cultivated cotton hosts (genus Gossypium) is poorly understood. Past studies using morphology, host use, and distribution records suggest that A.grandis grandis comprises three forms with host-associated characteristics: the southeastern form (from domesticated Gossypium hirsutum L., southeastern United States and northeastern Mexico), the thurberia form (from Gossypium thurberi Todaro, Arizona and northwestern Mexico), and the Mexican form (from multiple Gossypium species and other malvaceous plant genera in the remainder of Mexico and Central America). However, the phylogenetic relationships, host preferences, and distributions of these forms are not completely understood. An alternative hypothesis of an eastern and western form of the boll weevil is suggested by the suspected phylogeographic range expansion from an ancestral distribution in the tropics northward along both Mexican coasts, culminating in the maximally contrasting phenotypes observed in the northeastern and northwestern arms of the current distribution. In this study, we sequenced one mitochondrial and four nuclear genes to gain insight into the evolutionary relationships among the putative forms and their distributions on wild and domesticated cotton hosts. Using models of evolution, we compared the three-form to the two-form classification and to two alternative classifications that incorporate geography and host use traits. The genetic data at most loci provide stronger support for the two-form than the three-form hypothesis, with an eastern and western group separated by the Sierra Madre Occidental mountain range. They do not support separate taxonomic status for boll weevils developing onG. thurberi.

“…Insecticide use in cotton, Gossypium hirsutum L. (Malvaceae), has been reduced after the success of transgenic Bt (Bacillus thuringiensis) cotton and area-wide eradication of boll weevil, Anthonomous grandis grandis Boheman (Coleoptera: Curculionidae) (Edge et al 2001, Allen 2008). These advances have likely released the sucking bug complex of stink bugs and plant bugs (Hemiptera: Pentatomidae and Miridae) from indirect insecticide control (Lu et al 2010).…”

Verde plant bugs, Creontiades signatus Distant (Hemiptera: Miridae), were released onto caged cotton, Cossypium hirsutum L., for a 1-wk period to characterize the effects of insect density and bloom period of infestation on cotton injury and yield in 2011 and 2012, Corpus Christi, TX. When plants were infested during early bloom (10-11 nodes above first white flower), a linear decline in fruit retention and boll load and a linear increase in boll injury were detected as verde plant bug infestation levels increased from an average of 0.5 to 4 bugs per plant. Lint and seed yield per plant showed a corresponding decline. Fruit retention, boll load, and yield were not affected on plants infested 1 wk later at peak bloom (8-9 nodes above first white flower), even though boll injury increased as infestation levels increased. Second-year testing verified boll injury but not yield loss, when infestations occurred at peak bloom. Incidence of cotton boll rot, known to be associated with verde plant bug feeding, was low to modest (< 1% [2012] to 12% [2011] of bolls with disease symptoms), and drought stress persisted throughout the study. Caging effect was minimal: a 10% fruit retention decline was associated with caging, and the effect was not detectable in the other measurements. Overall, reduced fruit retention and boll load caused by verde plant bug were important contributors to yield decline, damage potential was greatest during the early bloom period of infestation, and a simple linear response best described the yield response-insect density relationship at early bloom. Confirmation that cotton after peak bloom was less prone to verde plant bug injury and an early bloom-specific economic injury level were key findings that can improve integrated pest management decision-making for dryland cotton, at least under low-rainfall growing conditions.

Perspective: service‐based business models to incentivize the efficient use of pesticides in crop protection

Several problems limit the productivity and acceptance of crop protection, including pesticide overuse, pesticide resistance, poor adoption of integrated pest management (IPM), declining funding for research and extension, and inefficiencies of scale. We discuss the proposition that alternative business models for crop protection can address these problems by incentivizing and benefiting from efficiency of pesticide use. Currently, business models are not linked to the adoption of IPM and are sometimes at odds with IPM practices. We explore a business model based on the provision of pest management adequacy through services rather than the sale of pesticide products. Specifically, we advocate for establishment of crop protection adequacy standards that would allow a market system to maximize efficiency. Changing some of the relationships between agricultural companies and producers from one based on products to one based on services is an idea worthy of debate and evaluation for improving the efficiency of pest management. Contemporary information technology enhancing monitoring and coordination warrants attention in this debate.
