Studying material from decayed fruits, dung, carrion, “sweeping” vegetation, Malaise, Moericke and light traps from Brazilian localities, four Alysiinae (Hymenoptera, Braconidae) species were found: Aphaereta confusa Wharton, 1994; Idiasta (Idiasta) delicata (Papp, 1969); Gnathopleura astarte (Haliday, 1838) and G. semirufa (Brullé, 1846) specimens. All these species have Neotropical distributi...

The objective of this study was to isolate and identify fungal species found in natural association with adults of Musca domestica. The adult insects were collected from two natural breeding grounds: hog pens and an urban sanitary landfill. The isolated fungi were identified as: Aspergillus flavus (23.8%), A. niger var. niger (14.4%), Penicillium corylophilum (21.4%), P. fellutanum (11.9%), Cla...

Horn fly immatures were raised in media containing different concentrations of diflubenzuron in order to verify their susceptibility to this insect growth regulator (IGR). The 50% and 95% lethal concentrations of diflubenzuron for the population (LC50, LC95) were determined as well as the effect of this IGR on the different immature horn fly stages. The tests were performed using the progeny of...

J. Econ.Entomol.78: 722-724 (1985) ABSTRACT A residue on glassexposure technique was compared with topical application as a method of assessingpermethrin resistance in a house fly (Musca domestica L.) population. Multiple levels of treatment permitted development of significant dosage-mortality lines with both techniques. Average resistance factors were ca. 150 with the topical application tech...

Stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae), once only a pest of pastured cattle, has become a serious pest of range cattle in the United States. Because of the difficulties associated with stable fly management under range conditions, a pesticide-impregnated cloth target is being developed as a management tool. We conducted studies to determine the influence of weather, time, fabr...

In the present contribution we compared the entomological succession pattern of a burned carcass with that of an unburned one. For that, we used domestic pig carcasses and focused on Calliphoridae, Muscidae and Sarcophagidae flies, because they are the ones most commonly used in Postmortem Interval estimates. Adult and immature flies were collected daily. A total of 27 species and 2,498 specime...

Brazilian studies involving entomological succession patterns in carcasses have been used to describe the necrophagous entomofauna of a determined municipality or region with forensic objectives. Following the same objectives, an ecological study with 10 calyptrate dipterans was carried out during the winter of 2007 and the summer of 2008 in the metropolitan region of the municipality of Rio de...

An unavoidable by-product of any animal production system, be it vertebrate- or invertebrate-based, is the manure generated by animals themselves. In this review, we focus on role that insects, particularly black soldier fly Hermetia illucens (L.) (Diptera: Stratiomyidae), could play in managing mass amount produced through agriculture, and subsequent commodities such a system. Although review ...

Rate of development of forensically-important Diptera in southern Brazil. Dipteran larvae were collected from rabbit (Oryctolagus cunniculus L.) carcasses during the four seasons in 2005 in the southernmost state of Rio Grande do Sul, Brazil. The larvae were fed ground beef at ambient temperatures following collection from carcasses. The development of each species under these conditions was es...
