Determining the age composition of a population is important when conducting ecological, taxonomic and environmental assessments. Morphometric measurements of the head capsule, especially the length and width, are widely used in the identification of insect instars, but alternative ways for determining the age of insects can expand the options for the analysis of field and laboratory populations. This study evaluated the morphometry of the antennae, mandibles, mentum and ventromental plates to discriminate among the four larval instars of Chironomus sancticaroli Strixino & Strixino, 1981. The larvae were reared in the laboratory under constant temperature (25°C) and photoperiod of 12/12 hours for 19 days, with a supply of food. Fifteen larvae were... |

ABSTRACT The objective of this work was to evaluate the occurrence and infestation rates of Streblidae species on bats in a semideciduous seasonal forest fragment in western Paraná, South of Brazil. A total of 289 specimens of eight Streblidae species were collected from six species of bats belonging to the family Phyllostomidae. The most frequent Streblidae species were Megistopoda proxima (Séguy, 1926), Aspidoptera falcata Wenzel, 1976 and Paratrichobius longicrus (Miranda Ribeiro, 1907). The highest prevalence found was Megistopoda aranea (Coquillet, 1899) on Artibeus planirostris (Spinx, 1823). The highest intensity found was M. aranea on Artibeus lituratus (Olfers, 1818). The highest abundance found was M. proxima on Sturnira lilium (E. Geoffroy,... |
