          Abstract

          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 (24º25' S and 52º48' 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.

          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 (24º25' S e 52º48' 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.

            Mechanism of aggregation behavior inMaladera matrida Argaman (Coleoptera: Scarabaeidae).

            AdultMaladera matrida Argaman (Coleoptera: Scarabaeidae: Melolonthinae) males emerge from soil for an active period at dusk, a few minutes before the females. Adults are found during most of the active hours on the foliage in aggregations composed of an equal sex ratio. The mechanism of aggregation behavior ofM. matrida beetles was studied in a Y-shaped olfactometer. No evidence was found for the existence of an aggregation pheromone released either by males or by females, but behavior tests indicate that adultM. matrida beetles, males as well as females, are attracted to volatiles of an injured host plant. The following scenario is suggested: Males emerge daily from soil at dusk, a few minutes before the females, and immediately start feeding. Additional males are attracted to the injured host's volatiles and form aggregations. When females emerge from soil, the attractant volatiles are concentrated in spots, and the females join the aggregations, forming an equal sex ratio.
