“…It is relevant yet to consider that this pest species is multivoltine, and as mentioned before, it can feed on soybean roots. Ávila and Parra (2002), when evaluating the D. speciosa development on different hosts, concluded that the insects' survival which fed upon soybean roots from the genotype IAC-8 was 30.1%, very close to the rate found on BRSGO 8360 in our study (31.0%). However, when comparing different hosts on the development of an insect, it is important to know the resistance of the studied genotypes, having in order the dissimilarity detected among the genotypes in this work, where the survival values ranged from 2.0 to 31.0%.…”

“…Ávila and Parra (2002), while studying the D. speciosa development on different genotypes, concluded that under field conditions, in the absence of a preferred host, the larvae of this species may use soybean plants as an alternative host for its feeding and breeding. In Brazil, Corseuil et al (1974) reported that larvae of D. speciosa feed on soybean plants roots.…”

“…The relative increase of corn consumption probably occurred to compensate the low nutritional quality of the leaf tissue in this host. Ávila & Parra (2002) observed that the ingestion of corn leaves negatively affected the reproduction and survival of D. speciosa adults. These authors also verified that the concentration of nitrogen was lower for corn and higher for potato plants; this differential leaf consumption by D. speciosa adults could be related to the amounts of nitrogen in the leaves of the tested hosts.…”

“…However, little research work has been carried out to determine the influence of host plants as food for the adult stage of the species (Ávila & Parra, 2001;2002). Reports on to this subject can help to understand the factors that determine the population dynamics of D. speciosa in the field, providing useful background information for the development of control tactics.…”

“…No estágio adulto, este inseto tem preferência por folhas de feijão e soja, mas pode atacar diversas culturas (MARQUES et al, 1999). Na fase larval, se alimenta de raízes principalmente de gramíneas, sendo o milho um de seus principais hospedeiros (ÁVILA & PARRA, 2002;WALSH, 2002). Seu controle é realizado quase que exclusivamente com inseticidas sintéticos, o que gera danos ao ambiente, além de reinfestação e resistência dos insetos (ARRUDA-GATTI & VENTURA, 2003).…”
