In this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) Chironomid larvae were examined. For this purpose, 2.5 grams of food per Coconut considered in the period, with three replicates and Chironomid larvae during the period of 15 days in plastic pans were kept in nutrition. The results ...
Feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae on different ratios of live food and microencapsulated diet (MED). Food consumption rate increased progressively with increasing larval weight. The results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to...
A new formula for insect rearing artificial diets without using any of their conventional gelling agents was provided in the present work, for the first time. Larvae of the Egyptian cotton leafworm, Spodoptera littoralis (Lepidoptera: Noctuidae) were successfully mass-reared, for nine consecutive generations on an agar-free artificial diet. This suggested medium is based on yellow lentils, Lens...
Incidences of potential per os Cydia pomonella granulovirus (CpGV) transmission within a large codling moth colony were identified. CpGV was detected in the water which is used to wash egg sheets. When pre-neonates were extracted from eggs prior to emergence and tested for the presence of CpGV, 40% were found to carry amounts of CpGV detectable by a polymerase chain reaction (PCR) assay, sugges...
Experiments were done to determine if transporting live screwworms Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae) for developing new strains from countries where foot-and-mouth disease and classical swine fever are endemic, to the mass rearing facilities in Mexico and Panama, may introduce these exotic diseases into these countries. Are screwworms capable of harboring and spreading f...
introduction: land use change, deforestation, grazing, intentional and unintentional fire and invasive pests and diseases are all the major cause of damage to the zagros forest ecosystem. the green oak leaf roller (tortrix viridana l.) is one of the important pests of zagros forests. larvae of the pest significantly damage the oak forests with feeding on leaves and buds of different species of ...
Background: The larvae of Lucilia sericata are efficiently and widely used in maggot therapy. The aim of this study was to investigate some environmental factors that influence the mass rearing of Lucilia sericata as the most suitable candidates for maggot therapy in Iran. Methods: This cross-sectional study was conducted in fli...
The silkworm, (B. mori L). is highly susceptible to pathogens such as protozoa, virus, bacteria and fungus. To evaluate the various bed disinfectant viz, Vijetha, Sericilin, Labex, Amla compare with untreated control for their suitability standardization management of diseases during silkworm rearing. rearing multivoltine hybrid race [NISTARI × (SK6×SK7)] was carried out in centre. In present s...
