“…Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae) ocorre em diversos países da América do Sul (ARÉSTEGUI, 1976;KRYSAN, 1986;BERCELLINI & MALACALZA, 1994). O adulto alimenta-se da parte aérea de plantas, enquanto a larva, de raízes e tubérculos (GASSEN, 1989).…”

“…al (1992) found that 60% of D. virgifera virgifera egg population was located in the 20-to 30-cm soil depth zone. D. v. virgifera eggs are deposited deeper in the soil than D. longicomis eggs, apparently an evolutionary response to the lack of cold hardiness in D. v. virgifera (Krysan 1986).…”

“…Diabroticite corn rootworms are important pests of maize, Zea mays L. Most damage in the U.S.A. results from larval feeding by northern, western, or Mexican corn rootworm, Diabrotica barberi (Smith and Lawrence), D. virgifera virgifera (LeConte), or D. virgifera zeae (Krysan and Smith), respectively (Krysan, 1986). Diabrotica v. virgifera also occurs in Europe, where it has expanded its range and attained pest status after its discovery near Belgrade in the early 1990s (Enserink, 1999).…”

1 Field studies evaluated plant attractants and analogues as tools to move corn rootworm beetles (Diabrotica spp.) into areas to be treated with toxic baits for population suppression via mass removal/annihilation of reproductive adults. 2 When dispensed from sticky traps in maize, 2-phenyl-1-ethylamine and 2-phenyl-1-ethanol captured more northern corn rootworm, Diabrotica barberi, than did 4-methoxyphenethanol. Only 2-phenyl-1-ethanol attracted the western corn rootworm, Diabrotica virgifera virgifera, but not until maize matured beyond milk stage. 3 Attraction of D. barberi to the amine, alone or blended with 2-phenyl-1-ethanol, occurred before and after maize flowered but not during intervening silk or blister stages. Attraction recurred during early milk stage at or before 50% emergence of adult female D. barberi or D. v. virgifera, respectively, and before populations declined for the season. 4 Synergistic interaction of 2-phenyl-1-ethylamine with 2-phenyl-1-ethanol in attracting D. barberi females did not occur until maize matured to late milk stage. 5 The amine-alcohol blend (0.44 point sources m À2 ) doubled the density of D. barberi but not D. v. virgifera when applied to small plots within mostly milk-stage or younger maize. Traps without bait within attractant-treated plots captured more female, but not male, D. barberi than did traps in untreated control plots, hinting that females accounted for most of the observed increase in beetle density. 6 The results suggest that attractants can be used despite phenological limitations to concentrate preovipositional females within field areas and thus to complement a variety of corn rootworm control strategies.
