Distribution of Leaf-Feeding Beetles and Bean pod mottle virus (BPMV) in Illinois and Transmission of BPMV in Soybean

Abstract

Bean leaf beetles (BLB; Cerotoma trifurcata) were collected in soybean (Glycine max) fields in 58 and 99 Illinois counties surveyed during the 2000 and 2001 growing seasons, respectively. In 2000, BLB counts were highest in the central portion of the state. BLB counts were lower the following year, but were more uniformly distributed throughout the state. BLB tested positive for Bean pod mottle virus (BPMV) in 37 of 41 counties assayed in 2000. In 2001, BLB tested positive for BPMV in 86 of 99 counties sampled. In 2000 and 2001, western corn rootworm (WCR; Diabrotica virgifera virgifera) adults were abundant in soybean fields only in east central Illinois. WCR adults tested positive for BPMV in 21 of 21 east central Illinois counties in 2000 and 20 of 24 sampled in 2001. BPMV was detected in soybean plants in 38 of 46 counties sampled in 2000. Field-collected WCR adults transmitted BPMV to potted soybean plants at low rates either directly from BPMV-infected soybean fields or with prior feeding on BPMV-infected plants. This is the first report of the distribution of BLB, WCR adults, and BPMV in Illinois and of BPMV transmission by adult WCR.

Climate and host plant availability impact the future distribution of the bean leaf beetle (Cerotoma trifurcata)

“…Because information on bean leaf beetle physiological tolerances is limited, we followed the methods of model fit from Sutherst et al . (), with parameters being adjusted primarily to match North American distribution and relative abundance data obtained from a variety of sources (Leonard & Turner, ; Nichols et al ., ; Herzog, ; Boiteau et al ., ; Loughran & Ragsdale, ; Payah & Boethel, ; Felton et al ., ; Pedigo, ; Tonhasca, ; Buntin et al ., ; Danielson et al ., ; Lam et al ., ; Srinivas et al ., ; Krell et al ., ; Mabry et al ., ; Riley et al ., ; Carrillo et al ., ; Park & Krell, ; Lundgren & Riedell, ; Hammack et al ., ; Vlach et al ., ; Musser et al ., ; Tiroesele et al ., ). Southern Ontario distribution data were obtained from extensive sampling in 2010 by T. Baute (unpublished data).…”

Insect communities in soybeans of eastern South Dakota: The effects of vegetation management and pesticides on soybean aphids, bean leaf beetles, and their natural enemies

“…Bean leaf beetle (Cerotoma trifurcata Forster [Coleoptera: Chrysomelidae]) is another predominant, but sporadic, pest of soybeans in this region. Adults of this pest defoliate soybean plants and transmit bean pod mottle virus (Mabry et al, 2003;Bradshaw et al, 2008;Byamukama et al, 2011), and larvae consume root nodules of the soybean plant and disrupt its nitrogen dynamics Riedell et al, 2011). These two pests support a diverse and abundant natural enemy community throughout much of the soybeanproducing region of North America (Toepfer et al, 2009;Ragsdale et al, 2011), but this natural enemy community has been poorly described in the Northern Great Plains (but see Seagraves and Lundgren, 2012 for one report).…”

Label-free virus detection using silicon photonic microring resonators

“…The most commonly used method for detection of BPMV is the sandwich enzyme linked immunosorbent assay (ELISA) (Mabry et al, 2003). This method, though highly sensitive, has a number of drawbacks that make it less than ideal for certain applications.…”

“…Severe infections can lead to up to 52% losses in crop yield due to smaller seed size and discoloration (Gergerich, 1999). Additionally, co-infection of crops with BPMV and Soybean mosaic virus (SMV) can lead to devastating reductions of crop yields of up to 85% (Mabry et al, 2003; Ross, 1968). Because of the large number of samples to be analyzed in monitoring the speed and breadth of disease transmission, it is clear that techniques capable of detecting viruses with minimal sample preparation and rapid time-to-result are valuable.…”
