. Cooperative economic insect report. Beneficial insects; Insect pests. INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES A SCARAB (Liogenys macropelma Bates) Economic Importance: This species is frequently intercepted in aircraft from Latin America. Since the genus Liogenys is classified in the subfamily Melolonthinae, tribe Macrodactylini, it follows that L. macropelma is photy- phagous in the larval stage and probably in the adult stage as well. Adults of Liogenys cribricollis are reported to attack Schinus latifolius and adults of L. tibialis are reported to feed on the foliage of peach tree
. Cooperative economic insect report. Beneficial insects; Insect pests. INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES A SCARAB (Liogenys macropelma Bates) Economic Importance: This species is frequently intercepted in aircraft from Latin America. Since the genus Liogenys is classified in the subfamily Melolonthinae, tribe Macrodactylini, it follows that L. macropelma is photy- phagous in the larval stage and probably in the adult stage as well. Adults of Liogenys cribricollis are reported to attack Schinus latifolius and adults of L. tibialis are reported to feed on the foliage of peach trees in Brazil. Although L. macropelma is not listed in "Reporte Preliminar Sobre Evalucion de Perdidas Causadas por Plagas y Enfermendades en los Cultivos Basicos de Consuma Interno en la Region del OIRSA" published in 1966, there is good reason to deter its entry and establishment in the United States. Hosts: Hosts of this scarab have not been determined nor has it been inter- cepted on any plant material. Interceptions: Since 1960, live adults have been intercepted 274 times as hitchhikers on aircraft from Latin America. The infestations are believed to have originated in Brazil, Costa Rica, El Salvador, Guatemala, Panama, and Venezuela. On several occasions, more than 80 specimens have been found aboard a single aircraft. Most have arrived in April or May although interceptions date from April 8 to October 8. The majority of interceptions usually come from Panama, arriving in the morning.
