The third instar of the Australian green lacewing Italochrysa insignis (Walker) is described and compared with that of the European Italochrysa italica (Rossi). Larvae of both species are associated with arboreal ant nests. Moreover, they share a substantial number of morphological adaptations that may defend them against ants and that distinguish them from larvae of other chrysopids. The larva...

F. judaica subsp. insignis is a rare taxon in Europe. So far, this has been reported only Croatia, from few localities along the Eastern Adriatic coast. now for first time flora of Bosnia and Herzegovina, its distribution extended to three new Dalmatia.

The dermis of sea cucumbers is a catch connective tissue or mutable collagenous tissue that shows large changes in stiffness. Extensive studies on the dermis revealed that it can adopt three different states having different mechanical properties that can be reversibly converted. These are the stiff, standard and soft states. The standard state is readily produced when a dermal piece is immerse...

Coastal waters of Pakistan have considerable biodiversity of sea cucumbers and to date 11 genera and fifteen species of sea cucumbers belonging to 3 families have been recorded. In the present study the biochemical composition and nutritional quality of two most common sea cucumbers (Holothuria arenicola and Actinopyga mauritiana) were determined. The study includes their proximate, amino acid,...

Sea cucumbers are found in various sea environments like sea floors from the deep sea to intertidal areas (Foster and Hodgson, 1995; Uthicje et al., 2009). Sea cucumbers belong to the phylum Echinodermata and they mainly feed on detritus containing organic matter, microalgae, and bacteria (Massin, 1982; Moriarty, 1982; Yingst, 1976). Gut microorganisms are important for digestion of diets, but ...

In order to search for sulfated polysaccharides in different invertebrate connective tissues and to examine their biological activities, we have isolated three types of polysaccharides from the body wall of the three sea cucumbers Holothuria edulis, Apostichopus japonicas and Holothuria nobilis. The physicochemical properties and anticoagulant activities of these polysaccharides were examined a...

The Culicoides communities have been analyzed between 1993/1998 in the area influenced by the Yacyret Dam Lake (Paran River, Argentina-Paraguay). Adults of Culicoides were collected monthly by using CDC light traps exposed for 24 h in 9 sampling sites located at both margins of the river; 21 species were recorded. Highest values of species richness were recorded during 1993/1994, being Quiter...
