Influence of Roundup Ready Soybean and Roundup Ultra Herbicide on Geocoris punctipes (Say) (Heteroptera: Lygaeidae) in the Laboratory

Roundup Ready® crops have become the dominant weed control system throughout the United States. Therefore, laboratory studies were conducted to evaluate the effects of Roundup Ready soybean, Glycine max (L.) Merrill, and glyphosate on the fecundity and mortality of Geocoris punctipes (Say). Mortality of third instars and adults (∼30 d old) and fecundity of females exposed to glyphosate by direct spray application or residual on soybean foliage were not affected over a 10-d posttreatment period. Mortality of nymphs and adults exposed to transgenic soybean foliage did not differ from mortality of nymphs and adults exposed to foliage of conventional, glyphosate-susceptible soybean. Exposure of G. punctipes eggs to glyphosate spray had no effect on egg hatch. The knowledge of the minimal effects of Roundup Ready soybeans and glyphosate on predaceous arthropods promotes the use of the Roundup Ready soybean system.

Narrow Row

Roundup Ready® soybeans, Glycine max (L.) Merrill, in narrow-row planting systems were investigated in 1998 in Mississippi to evaluate the effects of the transgenic crop and glyphosate herbicide on pest and beneficial insects. Insects found in sufficient numbers for meaningful analysis included adult bean leaf beetle, Cerotoma trifurcata (Forster); adult three-cornered alfalfa hopper, Spissistilus festinus (Say); adult big-eyed bug, Geocoris punctipes (Say), and; larvae of green cloverworm, Plathypena scabra (F.), and velvetbean caterpillar, Anticarsia gemmatalis (Hübner). Populations of C. trifurcata, S. festinus, P. scabra and A. gemmatalis were not reduced in genetically altered Roundup Ready soybean, or by recommended (by label) or delayed applications of glyphosate. Numbers of G. punctipes also were not reduced in Roundup Ready soybean, but were reduced by recommended applications of glyphosate during weeks three and four following the second recommended herbicide application. Geocoris punctipes densities also were reduced at 1 and 2 wks after the first glyphosate application in plots in which the second application of glyphosate was delayed. Numbers of G. punctipes may have been indirectly reduced by glyphosate within sample weeks two and three because of variations in weed densities after treatment with the herbicide.

Horseshoe Crabs

In 1964, Limulus amoebocyte lysate (LAL), developed from horseshoe crab blood, was discovered as an effective pryogen test. Limulus blood reacts to endotoxins by forming a gel. The LAL test, constructed from horseshoe crab amoebocytes, has become the standard test in the United States, Europe, and Asia to test pharmaceutical injectables and pharmaceutical insertables for biomedical and veterinary uses. Without it, endotoxins could contaminate all of our laboratory studies, our bodies, and other nonhuman animal bodies. We’ve made horseshoe crabs indispensable to our human and veterinary biomedicine. We need their blood, and as health care demand grows, we will need more and more. I explain how blood donations are detrimental to the crabs. Furthermore, I explain how the LAL test is a not lifesaving test but is instead used for quality control. Even with all of this information and the viability of a synthetic alternative, the bureaucracy surrounding the procedure for switching to the synthetic alternative will prevent the switch from happening until most of the crabs have died. They are not valued like humans are; they are instead valued for their use to humans and will be valued that way until they are used up.

Adult Preference

Abstract Laboratory studies were conducted with Dichelops furcatus (F.), Euschistus heros (F.), and Nezara viridula (L.) (Heteroptera: Pentatomidae) aiming to evaluate nymph and adult biology and adult preference for immature reproductive structures of the cultivated plants, soybean, Glycine max (L.) Merrill (Fabaceae), wheat, Triticum aestivum L. (Poaceae), and canola, Brassica napus L. var. oleifera (Brassicaceae). Considering the survivorship for D. furcatus nymphs, it was greater on soybean and wheat, for E. heros nymphs it was greater on soybean compared to canola and wheat, and for N. viridula nymphs the survivorship was greater on soybean and canola. Dichelops furcatus nymphs developed faster on soybean and wheat, and E. heros and N. viridula nymphs developed faster on soybean and canola. Body weight at adult emergency for D. furcatus was greater on soybean and wheat, and for E. heros and N. viridula, it was greater on soybean. Adult survivorship and longevity were similar on soybean/wheat/canola for D. furcatus and N. viridula, and greater on soybean for E. heros. Reproduction and weight gain of adults were greater on soybean and wheat for D. furcatus, and on soybean for E. heros; N. viridula reproduced only on soybean and tended to gain greater body weight in this food source. As expected, soybean considering its superior nutritional quality was, in general, the best food. These laboratory studies coupled with field observations allow to conclude that the sequence of soybean/wheat/canola crops in the area studied forms a ‘green bridge’ that favor stink bug populations abundance in southern Brazilian neotropics.
