Raising of horn fly haematobia irritans (L.) (diptera: muscidae) in laboratory by means of egg and larva inoculation

Several studies have required Haematobia irritans (L.) raising in laboratory. The present study assessed two methods of inoculating immature forms of H. irritans to obtain adults. In 2007, 15 Nellore steers (Bos indicus) (L.) were used for the collection of feces free of anthelmintic treatment and flies to produce for eggs and larva. For method I, 30 eggs were incubated in square filter paper (5 × 5 cm) and deposited on bovine feces (500 g) where they were kept until hatching and spontaneous penetration of larvae (L1) into the fecal mass. After 24 h, eggs were analyzed under a stereoscope microscope (40×) for the number of larvae that instinctively penetrated the feces. In method II, larvae were obtained only by natural egg hatching. At birth, 30 larvae were collected and individually inoculated, directly onto the fecal plate by employing a moistened brush. The tests were carried out at controlled temperature (28˚C ± 2˚C) and saturated humidity (80%) until the emergence of flies with both methods. The number of emerged flies was considered in the result. Using method I, 276 (76.7%) flies emerged from 360 inoculated eggs, while using method II, 283 (78.6%) flies emerged from 360 inoculated larvae. There was no significant difference (P = 0.7821) between methods for the number of flies; however, the proportion between males and females by means of larva inoculation was different from 1:1 (P = 0.0146). Results indicated that both methods led to a satisfactory production of flies and egg inoculation provided an easier establishment.

Description of the larva of Potamophilops cinereus (Blanchard) from Southeastern Brazil (Coleoptera, Elmidae, Larainae)

Larvae of Potamophilops cinereus (Blanchard, 1841) from Brazil, Sao Paulo, Ribeirao Grande (Fazenda Intervales, Rio Carmo) are described for the first time and illustrated. The larvae were found associated with adults. The larva of P. cinereus is most similar to larvae of species of the Mexican and Central American genera Disersus Sharp and Hispaniolara Brown, but can be easily distinguished chiefly by the head being not visible when seen from above, due to being concealed by the anterior projection of the pronotum. Comparisons of the three genera are presented. Photographs of the adult habitus of P. cinereus are also furnished. A key to the larvae of the genera of Larainae of Brazil is included.

Redescription of the larva of Amblyomma oblongoguttatum Koch, 1844 (Acari: Ixodidae) by light and scanning electron microscopy

The larval stage of Amblyomma oblongoguttatum Koch is redescribed using optical and scanning electron microscopy. Unfed larvae were obtained from a colony of A. oblongoguttatum originated from engorged females collected on domestic pigs from Monte Negro municipally (10 degrees 29'S, 63 degrees 32'W), State of Rondonia, Western Amazon, Brazil. Several characters are presented including the chaetotaxy of the idiosoma, palpi and Haller's organ, as well as morphological features of the idiosoma, gnathosoma and legs. In addition, the porotaxy (topographical and numerical patterns of integumentary structures) were presented by using a new nomenclature recently proposed. The chaetotaxy of the larvae of A. oblongoguttatum, in general, is similar to other Neotropical Amblyomma species. Three types of integumentary structures were observed on the idiosoma: lyrifissures, small glands, and large wax glands. Topographic and numerical patterns of the integumentary structures consisted of 5 pairs of large wax glands (1 dorsal/4 ventral), 24 pairs of lyrifissures (11 dorsal/13 ventral), and 49 pairs of small glands (28 dorsal/21 ventral). These topographic and numerical patterns found for A. oblongoguttatum show only minor differences when compared with patterns of other Amblyomma larvae, however, a few key features can be used for identification of these species.
