The effects of stocking density of eggs and larvae were studied related to the morphological deformities appearance, percentage of survival, and growth rate, in order to achieve the most suitable stocking density for eggs and larvae in incubators and rearing tanks. The egg stocking densities were 500, 700 and 900 g per incubator for great sturgeon, 500 and 1000g per incubator for Persian sturge...

The teasel, Dipsacus fullonum is known to catch invertebrates in its water filled leaf bases, but experimental testing of reproductive benefits of this have been lacking. We report the effects of insect supplementation/removal and water removal during spring/summer on Dipsacus in two field populations. There were no significant treatment effects on biomass, but addition of dead dipteran larvae ...

Certain dipteran flies larvae causing invasion of the tissues and organs of the humans or other vertebrates are called as myiasis, which feed on hosts dead or living tissues. It is well documented in the skin and hot climate regions; underdeveloped countries are affected more commonly. Oral cavity is affected rarely and it can be secondary to serious medical conditions.

Background & Aims of the Study: Malaria is an infectious disease by fever, chills and anemia; and splenomegaly genus Plasmodium parasite is the agent of it. One of the easiest and least expensive methods for preventionof this disease is removing the vector that usually has been done by insecticides and chemical pesticides, but now days due to the harmful effects of toxic chemic...

Aedes aegypti L. is the mosquito vector of yellow fever, dengue, zika, and chikungunya viruses. The prevention control such diseases usually rely on use chemicals, that can cause harm to human health environment. Vegetable oils with larvicidal activity are used as an alternative tool this insect. This study aimed evaluate vegetable from Caryocar coriaceum, Mauritia fIexuosa, Carapa guianensis, ...

Ziziphus mauritiana methanol crude extract was evaluated for its insecticidal properties against Aedes aegypti, Ae. albopictus, and Culex quinquefasciatus mosquito larvae. Bioassays larvae mosquitoes were done following World Health Organization’s guidelines. Late third and/or early fourth instar of larva assayed five different concentrations viz. 100, 150, 200, 250, 300 mg ml–1 Z. extracts. Fr...

BACKGROUND AND AIMS Debridement therapy with sterile bred larvae in non-healing wounds is a widely accepted safe and efficient treatment modality. However, during application in the contaminated wound bed microbial contamination with potential microbial pathogen spread after escape from the wound or after unreliable disposal procedure may happen, particularly in the case of not using bio-bags. ...
