Aggregation behavior of Phyllophaga cuyabana (Moser) (Coleoptera: Melolonthidae): relationships between sites chosen for mating and offspring distribution Neotropical Entomology
Garcia,Maria A.; Oliveira,Lenita J.; Oliveira,Maria C.N. de.
The aggregation behavior of Phyllophaga cuyabana (Moser) was studied and the hypothesis that the cluster distribution of larvae of this pest into the soil is related to the sites where females from the previous generation had aggregated for mating was investigated. Field observations and greenhouse experiments carried out in Londrina County, State of Paraná, South Brazil, indicated that: a) during flight, adult females of P. cuyabana select plants, which are more conspicuous for landing and/or attracting males; b) tall plants, nearby soybean fields, might be preferred because female adults do not move far from the mating sites before digging themselves into the soil to lay eggs; c) high density of eggs and larvae occurs close to the adult aggregation...

Feeding and oviposition preference of Phyllophaga cuyabana (Moser) (Coleoptera: Melolonthidae) on several crops Neotropical Entomology
Oliveira,Lenita J.; Garcia,Maria A.; Hoffmann-Campo,Clara B.; Amaral,Maria L.B. do.
Laboratory and greenhouse experiments were carried out to study food and oviposition preference by Phyllophaga cuyabana (Moser) on different plant species as Cajanus cajan L. (pigeon pea), Crotalaria juncea L. (sun hemp), Crotalaria spectabilis Roth (showy crotalaria), Crotalaria ochroleuca G. Don (slenderleaf rattlebox), Glycine max [L.] Merrill (soybean), Gossypium hirsutum L. (cotton), Helianthus annuus L. (sunflower), Stizolobium aterrimum [Mucuna aterrima] Piper & Tracey (velvetbean) and Zea mays L. (mayze). In no-choice experiments, the number of eggs layed in sunflower, C. juncea and soybean was larger compared to cotton. Despite the fact that the adults did not discriminate among plants, in dual-choice test, the proportion of eggs layed and...

Occurrence of adults and biological aspects of Geniates borelli Camerano (Coleoptera, Scarabaeidae, Rutelinae) in Aquidauana, MS, Brazil Rev. Bras. entomol.
Rodrigues,Sergio Roberto; Barbosa,Crislany Lima; Abot,Alfredo Raul; Ide,Sérgio.
Occurrence of adults and biological aspects of Geniates borelli Camerano (Coleoptera, Scarabaeidae, Rutelinae) in Aquidauana, Mato Grosso do Sul, Brazil. Due to the importance of Geniates borelli Camerano as a pest in many crops, studies were developed at Universidade Estadual de Mato Grosso do Sul, Aquidauana campus, MS, Brazil. Adults were collected with a light trap from January 2006 to December 2007. 3,320 adults were collected, and the highest quantities were obtained in October 2006 and November 2007, with 1,548 and 802 adults recorded, respectively. Collected adults were kept in plastic containers with soil and Brachiaria decumbens seedlings for oviposition. 535 eggs measuring 2.30 × 1.60 mm were obtained. As the embryonic development progressed,...

Occurrence of Quesada gigas on Schizolobium amazonicum trees in Maranhão and Pará States, Brazil. Repositório Alice
ZANUNCIO, J.C.; PEREIRA, F.F.; ZANUNCIO, T.V.; MARTINELLI, N.M.; PINON, T.B.M.; GUIMARÃES, E.M..
An infestation of Quesada gigas Olivier (Hemiptera: Cicadidae) on "paricá" Schizolobium amazonicum (Huber) Ducken (Fabales: Fabaceae) was reported in the Municipalities of Itinga, Maranhão State and Paragominas, Pará State. Nymphs of this insect on roots and adults and exuvias on trunks of the plant were observed. Exit holes of nymphs in the soil were also observed. The occurrence of Q. gigas on S. amazonicum shows the damage potential of this species and the necessity of developing integrated management programs for species of this group, specially in reforested areas with "paricá".

Ocorrência e aspectos biológicos de Anomala testaceipennis Blanchard (Coleoptera, Scarabaeidae) Rev. Bras. entomol.
Rodrigues,Sérgio Roberto; Puker,Anderson; Abot,Alfredo Raul; Barbosa,Crislany de Lima; Ide,Sérgio; Coutinho,Gilmar Vieira.
Os coleópteros da família Scarabaeidae são importantes pragas em áreas de culturas e pastagens, principalmente devido à ação das larvas, as quais danificam o sistema radicular. São escassas as informações sobre esse grupo de pragas, desta forma, o presente trabalho teve por objetivo estudar a ocorrência e o ciclo biológico de Anomala testaceipennis Blanchard, 1856. De novembro de 2005 a novembro de 2006 foram realizadas coletas diárias com uma armadilha luminosa, e em laboratório os adultos foram mantidos em recipientes plásticos, contendo solo e mudas de Brachiaria decumbens, para estudo de biologia. Foram coletados 263 adultos de A. testaceipennis, em quase todos os meses do ano, não sendo registrados apenas em março e junho. Sobre a biologia...

Seasonal and vertical distribution of Phyllophaga cuyabana (Moser)(Coleoptera: Melolonthidae) in the soil profile Neotropical Entomology
Oliveira,Lenita J; Farias,José R B; Hoffmann-Campo,Clara B; Amaral,Maria L B do; Garcia,Maria A.
Phyllophaga cuyabana (Moser) temporal and vertical distribution patterns were evaluated in the soil profile, in order to subsidize methodology for population sampling, aiming at its management. In insect surveys carried out during three years, in Boa Esperança County, State of Parana, Brazil, Phyllophaga cuyabana was univoltine, with little overlap of the larval stages. Population peaked during December-February, but declined during the colder months, when larvae were in diapause. Different developmental stages exploited distinct soil depths. Eggs and early first instars tended to concentrate between 5 cm and 10 cm deep, but they spread more uniformly through the soil profile, reaching depths up to 30 cm, as they developed. Adults and eggs occurred in the...
