b a ckground: several important diseases are transmitted by mosquitoes. despite of the potential of the occurrence of some mosquito-borne diseases such as west nile, dirofilariasis and malaria in the region, there is no recent study of mosquitoes in west azerbaijan province. the aim of this investigation was to study the fauna, composition and dis- tribution of mosquitoes and the characteristic...

the present study explored the embryonic and larval development of an endangered fish species nandus nandus and resolved larval growth performances with the dietary supplementation of different types of lipids. fertilized eggs were collected from fiber glass tanks immediately after spontaneous spawning of n. nandus, which were fed with a 1% phospholipid (squid meal) supplemented diet for 3 mont...

The consumption of high-quality pollen induces the development of the hypopharyngeal glands in young honey bee workers. As protein-rich secretions from these glands are an important component of larval food, a direct relationship between pollen supply and brood rearing can be suspected. Consequently, the availability of pollen is likely to be a central parameter influencing the development of h...

Variation in local environmental conditions can have pronounced effects on the population structure and dynamics of marine organisms. Previous studies on crown-of-thorns starfish, Acanthaster planci, have primarily focused on effects of water quality and nutrient availability on larval growth and survival, while the role of maternal nutrition on reproduction and larval development has been over...

There is widespread concern regarding the effects of agro-chemical exposure on bee health, of which neonicotinoids, systemic insecticides detected in the pollen and nectar of both crops and wildflowers, have been the most strongly debated. The majority of studies examining the effect of neonicotinoids on bees have focussed on social species, namely honey bees and bumble bees. However, most bee ...

The third larval instar of Goliathus goliatus (Drury, 1770), Goliathus orientalis Moser, 1909 and Goliathus albosignatus Boheman, 1857 are described and illustrated for the first time and compared with the immature stages of other Cetoniinae. Larval development of Goliathus goliatus is investigated under laboratory conditions, with particular emphasis on food requirements. These results support...
