Genetic variation in a continuously breeding population of Danaus plexippus L. (Lepidoptera: Nymphalidae)

Variation at 4 genetic loci (Pgm; Me; Idh; Hbdh) was studied in a population of monarchs (Danaus plexippus L.) not subject to migration to overwintering sites. Adult insects were sampled from 18 milkweed patches in 5 widely spaced locations in south-east Queensland (Australia). Genetic differentiation between sub-populations (patches) was high (F= 0·032). For 2 loci (Me and Idh) both males and females showed significant differentiation between patches. Idh showed a significant cline with latitude in males only and Me showed no apparent geographic pattern in either sex. Both loci showed significant differences in gene frequencies between sexes. Possible mechanisms for maintaining these differences are discussed

Forma de estudo: Clínico retrospectivo. Material e método: Foram reportados 56 casos de corpos estranhos animados em orelhas (55 insetos e 1 aracnídeo) e 1 caso (inseto) em fossas nasais. O material foi coletado no setor de Emergência do serviço de ORL do Hospital Municipal Souza Aguiar, no centro do Rio de Janeiro, entre os anos de 1998 e 2000, e identificado por zoólogos do Museu Nacional, Rio de Janeiro. A maior parte dos casos ocorreu em Nova Iguaçu e Campo Grande, sendo analisados os quadros clínicos e as complicações ocorridas. Resultado: Os insetos são: 30,35% Blattaria (baratas); 25% Diptera (moscas e mosquitos); 12,5% Lepidoptera (borboletas e mariposas); 10,7% Coleoptera (besouros); 7,15% Hemiptera (percevejos, cigarras, afídeos, etc.), 5,35% Hymenoptera (vespas, abelhas, formigas, marimbondos) e 5,31 % outros.<br>Study design: Clinical retrospective. Material and method: Fufty-six cases of animated foreign bodies collected inside human ears (55 insects and 1 arachnid) and one case collected in nasal fossae (insect) were reported. The material was collected in the Emergency sector of Souza Aguiar Hospital, in Rio de Janeiro, between 1998 and 2000, and was identified by zoologists of Museu Nacional, Rio de Janeiro. Most of the cases had occurred in Nova Iguaçu and Campo Grande, suburbs of Rio de Janeiro. Clinical features and complications were analyzed. Results: The recorded insects are: 30,35% Blattaria (cockroaches); 25% Diptera (flies and mosquitos); 12,5% Lepidoptera (butterflies and moths); 10,7% Coleoptera (beetles); 7,15% Hemiptera (bugs, cicads, aphids, etc.), 5,35% Hymenoptera (wasps, bees, ants, and sawflies) and 5,31 % others
