“…Although C. trifurcata is native to North America and, prior to soybean emergence, feeds on wild native legumes, several herbaceous plant species, and leguminous crops such as alfalfa and sweet clover (Waldbauer & Kogan, ; Helm et al , ; Hammack et al , ), it is possible that those resources are not sufficiently abundant to support development of large populations. For example, Jeffords et al () noted large C. trifurcata populations and subsequent pest problems in Illinois, U.S.A., in a year when its emergence was well synchronized with soybean emergence, but small early season C. trifurcata populations and few subsequent pest problems in a year when soybean planting was delayed because of wet spring weather.…”

1 Bean leaf beetle Cerotoma trifurcata (Förster) (Coleoptera: Chrysomelidae) is a pest of soybean in the U.S.A. and is becoming a concern in Canada. The projected increase in winter temperatures under climate change could affect overwinter survival, timing of spring emergence and, ultimately, the severity of this pest. 2 We assessed the potential effects of warmer winters in field experiments performed in three consecutive years. Three warming levels were applied: (i) heated approximately 4 ∘ C above ambient; (ii) unheated with snow cover left intact; and (iii) unheated with snow cover removed. Survival and date of emergence were assessed in all years, and beetle lipid content was analyzed in 1 year to determine rates of energy use. 3 Overwinter survival was 6.5-14.5% among years. Winter warming inconsistently affected overwinter survival: increasing survival in one winter, decreasing survival in the warmest winter and having no effect in one winter. Beetles that received supplemental winter warming emerged approximately 2 weeks earlier in spring, and lipid content did not differ among treatment groups. 4 Earlier spring emergence may allow for the production of an additional generation per year of C. trifurcata under future climate change. However, further experiments are required to establish the relationship between overwinter survival and subsequent beetle population growth to determine potential pest status and best management practices under future climate conditions.

“…A number of classical monitoring methods are available for leaf beetles, such as vacuum sampling, sweeping, and ground cloth methods (Ruesink & Haynes, 1973;Turnipseed, 1974). In addition, emergence traps from soil have also been used (Boiteau et al, 1979;Jeffords et al, 1983). Monitoring methods for the cereal leaf beetle (Bai et al, 2001) have been studied intensively.…”

This paper provides reviews of the most commonly used methods to detect plant pests belonging to groups of invasive organisms with high economic relevance, including Coleoptera (bark beetles, flathead borers, leaf beetles, longhorn beetles, weevils), Diptera (cone and seed flies, fruit flies), Homoptera (aphids, leafhoppers and psyllids, whiteflies), Lepidoptera (moths and butterflies), Thysanoptera (thrips), bacteria (potato brown rot Ralstonia solanacearum) and fungi (pitch canker disease Gibberella circinata, brown rot disease Monilinia fructicola). Future perspectives in detection methods are discussed, with particular reference to the considerable increase in the volume, commodity type and origins of trade in plant material from third countries, the introduction of new crops, the continuous expansion of the EU with new border countries being added, and the impact of climate change affecting the geographical boundaries of pests and their vectors.

“…Insecticide applications are the primary management option when beetles exceed the appropriate economic threshold (Pedigo 1994). Bean leaf beetles overwinter in the adult stage in leaf litter in wooded areas , Loughran and Ragsdale 1986, Jeffords et al 1983, and at Nebraska's latitude have two generations during the summer months (Kogan et al 1974, Waldbauer and Kogan 1976, Smelser and Pedigo 1991.…”

The bean leaf beetle, Cerotoma trifurcata (Forster) (Coleoptera: Chrysomelidae), is a major insect pest of soybean in Nebraska and throughout much of the Midwest. This insect overwinters in the adult stage in litter in wooded areas such as shelterbelts. Historically, crop producers have been unsure of the merits of shelterbelts, especially if nearby crops are more likely to be infested by insect pests as a result. In this study, bean leaf beetle adults were sampled during the season by visually counting the number of beetles found on soybean plants early in the season and by sweep net sampling once plants were at the V4 stage (approximately 0.33 m tall). Sampling was done in 1997 and 1998 at the University of Nebraska Agricultural Research and Development Center in Saunders Co. in east-central Nebraska. Beetle counts were compared between shelterbelt-protected and -unprotected fields. In general, bean leaf beetles were more numerous in 1997 than in 1998, with abundance peaks occurring in late-July and early-September in both years. There were significant differences in bean leaf beetle counts from protected and unprotected fields on only three of the 11 and four of the 13 sampling dates in 1997 and 1998, respectively. On the sampling dates when significant differences were found, two of three in 1997 and three of four in 1998 had higher bean leaf beetle abundance in the protected soybean fields. The results of this study indicate a tendency for more bean leaf beetles in shelterbelt-protected soybean fields when differences are found, but beetle numbers were not significantly different between protected and unprotected fields on the majority of sample dates in the two years of this study. This study also reconfirms the presence of two generations of the bean leaf beetle in Nebraska.
