during a search of burrows for the purpose of capturing rodents in 1972, a number of soil samples were inspected for the collection of sand fly larvae. in this study, a total of 472 plastic bags of soil samples were collected from different depths of 30 rodent burrows. fourteen of these samples were found positive, from which 27 larvae were removed. most of the larvae were found in the depths o...

This study examined the effects of a commercial Lactobacillus probiotic on growth, survival and resistance of western white shrimp (Litopenaeus vannamei) larvae against salinity and formalin stresses in Persian gulf and Oman sea ecology research center. In this experiment, larvae were fed on 6 times a day from mysis I (M1) step to post larvae 5 over 3 treatments with 3 repetitions including a c...

Survey of fish larvae abundance, diversity and distribution was carried out in different habitats of Khark and Kharko coralline islands and islets from July 2006 to June 2007 over 12 stations. Khark and Kharko ecosystems are protected areas and wildlife refuges in northern point for fringing coral reefs in Iranian side of the Persian Gulf. This investigation was a part of the national Integrate...

Tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most destructive pests of tomato in many parts of the world including Iran. The toxicity of emamectin benzoate alone and combined with acetamiprid, eforia (thiamethoxam + lambda-cyhalotrin) and hexaflumuron was evaluated against 2nd instar larvae of Tuta absoluta (Meyrick) under 25 ± 1 °C, the relative humidity of ...

The aim of this study was to determine the inhibitory effects of feed ingredients on protease activities of Argyrosomus regius larvae using in vitro techniques. A. regius larvae fed on a commercial feeding procedure were sampled thirteen times, during the sampling period (from 3 to 32 days after hatching (DAH)). The differences observed in protease activities of meagre larvae during the samplin...

results significant differences were observed in the results of co-culture of nematodes larva and fungi after seven days. the most effective fungi against the nematodes larvae were cladosporium sp., trichoderma sp., fusarium equisetti, after seven days of incubation. materials and methods sheep feces were employed to provide the required third stage larvae source for the experiments. the nemato...
