-Phyllophaga cuyabana is a univoltine species and its development occurs completely underground. Its control by conventional methods, such as chemical and biological insecticides, is difficult, so it is important to understand its dispersion, reproduction, and population behavior in order to determine best pest management strategies. The objective of this work was to study the behavior of adults of P. cuyabana. This study was carried out in the laboratory, greenhouse and field sites in Paraná State, Brazil (24 o 25' S and 52 o 48' W), during four seasons. The results obtained demonstrate that: a) P. cuyabana adults have a synchronized short-flight period when mating and reproduction occurs; b) adults tend to aggregate in specific sites for mating; c) the majority of adults left the soil on alternate nights; d) the choice of mating and oviposition sites was made by females before copulation, since after copulation adults did not fly from or bury themselves at nearby locations; e) females that fed on leaves after mating, oviposited more eggs than females that had not fed; f) plant species such as sunflower (Helianthus annuus) and the Crotalaria juncea are important food sources for adults.Index terms: Glycine max, white grub, host plants, oviposition, pests of plants. Comportamento de vôo, de alimentação e de reprodução de adultos de Phyllophaga cuyabana (Moser) (Coleoptera: Melolonthidae)Resumo -Phyllophaga cuyabana é uma espécie univoltina cujo desenvolvimento ocorre no solo. Seu controle por inseticidas químicos e biológicos é difícil, assim é importante entender sua dispersão, reprodução e comportamento populacional a fim de identificar estratégias potenciais de manejo dessa praga. O objetivo deste trabalho foi estudar o comportamento de adultos de P. cuyabana. O estudo foi realizado em laboratório, casa de vegetação e campo, no Estado do Paraná, Brasil (24 o 25' S e 52 o 48' O), durante quatro safras. Os resultados obtidos demonstraram que: a) os adultos de P. cuyabana têm um vôo sincronizado durante um curto período quando ocorre o acasalamento e reprodução; b) os adultos tendem a se agregar em sítios específicos para o acasalamento; c) a maioria dos adultos deixa o solo em noites alternadas; d) a escolha do sítio de acasalamento e oviposição é feita pelas fêmeas antes da cópula; após a cópula os adultos não voam e se enterram em locais próximos; e) as fêmeas que ingerem folhas após o acasalamento ovipositam mais que as fêmeas que não se alimentam; f) espécies vegetais como girassol (Helianthus annuus) e Crotalaria juncea são importantes fontes de alimento para os adultos.Termos para indexação: Glycine max, coró, planta hospedeira, postura, praga das plantas.

“…This has been shown for scarabaeid (Domek and Johnson, 1988;Harari et al, 1994;Loughrin et al, 1995b) and chrysomelid beetles (Peng and Weiss, 1992;Bolter et al, 1997;Kalberer et al, 2001). The Colorado potato beetle, a chrysomelid, is more attracted not only to potato plants damaged by conspecifics rather than undamaged plants (Bolter et al, 1997;Landolt et al, 1999) but also to plants treated with insect regurgitant or the synthetic elicitors of odor emissions volicitin and methyl jasmonate (Landolt et al, 1999), as well as to plants exposed to damaging ozone levels (Schutz et al, 1995).…”

“…In general, it appears that in the systems where induced plant volatiles are known to attract natural enemies, herbivores prefer odours from healthy plants (Turlings & Benrey, 1998). Attraction to plants that are already damaged by conspecifics is usually found for adult Coleoptera (Harari et al, 1994;Loughrin et al, 1995;Bolter et al, 1997;N. Kalberer, pers.…”

When maize plants, Zea mays L., are mechanically damaged and the damaged sites are treated with caterpillar regurgitant, the plants will release a specific blend of volatiles. It is known that these volatiles can be attractive to natural enemies of herbivores. We hypothesise that the plant volatiles constitute part of the induced plant defence and that herbivores will be affected by the odours as well. In laboratory and semi-field studies this hypothesis was tested for the aphid Rhopalosiphum maidis (Fitch) (Rhynchota, Sternorrhyncha, Aphididae).In a Y-tube olfactometer significantly more aphids chose the odour of healthy, undamaged maize seedlings when tested against clean air or plants treated with regurgitant. Clean air was chosen more often when tested next to the odour of treated plants. This apparently repellent effect of the odour of treated plants was significant for winged aphids, but not for the wingless aphids.In field experiments aphids were released in the centre of circles of eight potted maize plants. Four plants in each circle were damaged and treated with caterpillar regurgitant while the other plants were left unharmed. At different intervals after aphid release, the number of aphids was counted on each plant. Significantly fewer winged and wingless aphids were found back on treated plants than on healthy plants.We suggest that herbivores may be repelled by the odours because they could indicate that: 1) the plant has initiated the production of toxic compounds; 2) potential competitors are present on the plant; 3) the plant is attractive to parasitoids and predators. Aphids may be particularly sensitive to induced maize volatiles because one of the major compounds emitted by the plant is (E)-β-farnesene, which is a common alarm pheromone for aphids. Collections and analyses of the odours emitted by crushed R. maidis confirmed that it too emits (E)-β-farnesene when stressed. The results are discussed in context of plant defence strategies and their possible exploitation for the control of pest insects.
