Especies del complejo de jobotos (Phyllophaga spp., Anomala spp y Cyclocephala spp.) asociadas a cultivos, en el Valle Central y Pacífico seco de Costa Rica.

Abstract

During 1990 and 1992 speciesofthe white grubs complex Phyllophaga, Anomala and Cyclocephala) were found associated to agricultural crops and to different groups of soils, in cultivated arcas of the Central Valley and Dry Pacific of CostaRica.White grubs raster and male genital, observed with the scanning electron microscope (SEM), were used to identify genera and species. Larvae and adults were identified as Phyllophaga menetriesi, P. obsoleta, P. zunilensis, P. elenans, P. vicina and P. valeriana; Cyclocephala lunulata, C. castaniella and C. sanguinicollis; and Anomala cupricollis and A. granulipyga. The distribution in agricultural crops was: P. menetriesi and P. vicina on coffee (Coffea arabica); P. menetriesi on asparagus (Asparagus officinalis); P. menetriesi, P. obsoleta, P. zunilensis, Anomala spp., Cyclocephala spp., Cyclocephala lunulata on strawberry (Fragaria anannas); P. zunilensis, P. elenans on sugar cane (Saccharum officinarum); P. valeriana on potatoe (Solanum tuberosum) and tomatoe (Lycopersicon esculentum); P. obsoleta, C. castaniella, C. sanxuinicollis and A. granulipyga on kikuyu grass (Penissetum clandestinum) P. menetriesi larvae were found in Andisols grand groups: Melanudands, Hapludands and Haplustands. P. obsoleta in the Melanudands grand group. P. vicina in Hapludands. P. valeriana in the Inceptisols grand group of Ustropepts. Anomala spp. in Hapludands and Cyclocephala spp. in Hapludands and Melanudands.

Attraction of Adults of Cyclocephala lunulata and Cyclocephala barrerai (Coleoptera: Scarabaeoidea: Melolonthidae) towards Bacteria Volatiles Isolated from Their Genital Chambers

“…Several genera of the Melolonthidae family as phytophages are pests of various crops [ 1 , 2 ]; among these is the genus Cyclocephala [ 3 ], which has been the less-studied of the family. Members of this genus are widely distributed across the Americas [ 4 ], and species such as Cyclocephala lunulata and Cyclocephala barrerai are important pests of diverse plant species like strawberry, guava, and ornamental pastures [ 2 , 5 , 6 ]. For the monitoring and management of these beetle species, studies have been carried out to take advantage of the substances involved in intraspecific interactions [ 7 , 8 , 9 , 10 ], focusing on volatile organic compounds involved in attracting a partner for copulation, such as sex pheromones [ 11 , 12 ].…”

Relación entre el estrés y las bacterias entomopatógenas Pantoea (Erwinia) agglomerans (herbicola) y Bacillus cereus en jobotos (Col: Melolonthidae) (Phyllophaga spp., Anomala spp. y Cyclocephala spp.), en Costa Rica.

“…Esto podría ser respaldado con lo afirmado por Isakova, 1954 y citado por Tanada (1963), cuando ha indicado que la virulencia e infectividad de las bacterias de la entomofauna, ha sido asociado con las relaciones sinergísticas o antagónicas que ocurren entre ellas. P. agglomerans no produce esporas, no obstante es un habitante común del suelo, por esta razón ha sido aislada de larvas de jobotos que se han encontrado en clases de suelo tales como Melanudands, Ustropets y Haplustands (Quesada y Abarca, 1997).…”
