The limnephilid caddisfly Dicosmoecus gilvipies (Hagen) occurs in many streams of northwestern United States and British Columbia. Because of the large size of the fully grown larva, its synchronous emergence pattern, and its frequent imitation by fly-fishing anglers, D. gilvipes is one of the best known North American aquatic insects. Egg masses are found at the bases of Carex sedges. Cases of...

Insect resistance to toxins exerts not only a great impact on our economy, but also on the ecology of many species. Resistance to one toxin is often associated with cross-resistance to other, sometimes unrelated, chemicals. In this study, we investigated mushroom toxin resistance in the fruit fly Drosophila melanogaster (Meigen). This fruit fly species does not feed on mushrooms in nature and m...

Practices for endo and ectoparasite control in beef cattle were evaluated in two independent experiments. First, the effects of rotenone on Rhipicephalus (Boophilus) microplus ticks were evaluated in vitro and in experimentally infected calves. In the second trial, the effects of grazing systems associated with endo and ectoparasite treatments on parasite burden and weight gain of naturally par...

Strongyloidiasis is an infectious disease caused by the Strongyloides stercoralis larvae, which penetrate the skin, go through the lymphatic circulation, and migrate to the lungs before reaching the intestines. They mature and may cause cutaneous strongyloidiasis, known as larva currens because of the quick migratory rate of the larva. The authors describe a case in which the larvae did not fol...

the identification of different species of simuliidae, also called “black fly”, is based on particular structure of oral and terminal appendages of their larvae add also on the special morphology of adults and pupaes. because of their considerable flight range, the problem of finding their resting places, and also the difficulties of collecting the adult flies, breeding of this insect, in the l...

Abstract The objective was to determine the effects of different drying methods on nutrient utilization black soldier fly (BSF; Hermetia illucens) larva meals using in vitro assays. Two-step and 3-step assays were employed simulate gastrointestinal tract pigs. Four used obtain BSF meal sources: 1) microwave-drying for 32 min, 2) hot-air at 60°C 17 h, 3) water blanching 5 min 4) 2% citric acid s...

Sampah merupakan salah satu permasalahan krusial. Pengelolaan sampah yang kurang komperehensif dapat memicu terjadinya pencemaran dan kerusakan lingkungan.

Masyarakat sebagai sumber utama penghasil diharapkan berpartisipasi aktif dalam kegiatan pe...

Eriopis connexa (Germar) (Coleoptera: Coccinellidae) occurs in several countries of South America and its mass rearing is important for biological control programmes. This work evaluated biological aspects of E. connexa larva fed on eggs of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) frozen for one day, fresh eggs of Dia...

we report a case of human nasal nosocomial myiasis in a 69-year-old rural man with numerous live maggots in nostrils. the patient was admitted in emergency ward due to dyspnea. after 72 hours the companion of patient discovered larva. the presence of the third instar larva indicated that the infestation was not more than three days. the collected instars were cleared, fixed and morphological st...
