Orius insidiosus (Say) as a predator of the soybean aphid, Aphis glycines Matsumura

Thiamethoxam Toxicity and Effects on Consumption Behavior in Orius insidiosus (Hemiptera: Anthocoridae) on Soybean

“…This concentration range corresponds to those that aphids are likely to encounter in soybean fields and that allow survivorship of the aphids (Magalhaes et al 2009). Based on the consumption behavior of O. insidiosus reported by Rutledge and O'Neil (2005), a prey density of 20 aphids was placed in each experimental unit.…”

“…The arrival of O. insidiosus to the fields in northern states has been reported to occur mainly in June through July (Rutledge and O'Neil 2005). During these months, soybean crops in the north central United States can develop from early to mid-vegetative stages (VC-V5) through early reproductive stages (R1-R2; Pedersen and Lauer 2004).…”

“…Orius insidiosus (Say) (Hemiptera: Anthocoridae) is one of the key predators of A. glycines in the United States (Rutledge et al 2004, Rutledge and O'Neil 2005, Butler and O'Neil 2007a, Butler and O'Neil 2007b, Ragsdale et al 2007). Consumption of A. glycines by nymphs and adults of O. insidiosus can effectively suppress population growth of this pest in soybean fields (Rutledge and O'Neil 2005).…”

“…Consumption of A. glycines by nymphs and adults of O. insidiosus can effectively suppress population growth of this pest in soybean fields (Rutledge and O'Neil 2005). The efficiency of this predator to control soybean aphid populations has been related with its time of migration and establishment in soybean fields (Rutledge and O'Neil 2005).…”

Biotic and Abiotic Influences on Within-Plant Distribution of Soybean Aphid (Hemiptera: Aphididae: Aphis glycines)

“…Natural enemies are capable of suppressing soybean aphid populations (Fox et al, 2004;Costamagna and Landis, 2006;Desneux et al, 2006;Brosius et al, 2007). The presence of natural enemies influences the withinplant distribution of many aphid species (Roitberg et al, 1979;Gonzales et al, 2001), and potentially soybean aphid (Rutledge and O'Neil, 2005). Therefore, it is reasonable to assume that the presence of natural enemies may have an effect on the distribution of soybean aphids found within the canopy.…”
