“…Injury on the leaves of young maize plants are very similar to that caused by the fall armyworm. This might mislead the diagnostic in the field (Cruz et al 1997;Roberto et al 2001;Ávila and Milanez 2004). Other Diabrotica species from temperate regions also present similar feeding habits (Branson and Krysan 1981;Elliott et al 1990).…”

“…Beetles population peaks were reported in February in Paraná during three years of sampling (HOHMAN & CARVALHO, 1989). In recent years, rising populations of D. speciosa have been reported on several crops during almost the entire year (ROBERTO et al, 2001). One probable explanation for beetle increasing populations include the introduction of the latter growing season maize but studies were not carried out to confirm this hypothesis.…”

“…A espécie D. speciosa causa elevadas perdas em inúmeras culturas, em sua fase adulta, alimentando-se da parte aérea de leguminosas (folhas largas), (ZUCCHI et al, 1993), uva (Vitis vinifera L.) (ROBERTO et al, 2001) e trigo (Triticum aestivum L.) (CIVIDANES et al, 1987).…”

“…Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae) é um inseto polifago, considerado uma das mais importantes pragas agrícolas da América Latina (VENTURA et al, 2001). Os adultos danificam a parte aérea de diversas culturas como as hortaliças (solanáceas, cucurbitáceas, crucíferas), feijoeiro, soja, girassol, milho causando desfolha, podendo se estender posteriormente às flores e às vagens (CARVALHO et al, 1982) e em alguns casos são vetores de patógenos (LAUMANN et al, 2003).…”
