background: maggot therapy has recently attracted considerable attention as an emerging debridement technique for wound healing. this study aimed to review the safety, effectiveness and economic evaluations of maggot debridement therapy for wound healing.   methods: to retrieve the relevant evidences, the cochrane library (until september 2014) was searched by appropriate keywords, using free t...

Scant attention has been paid to invasive species whose range and abundance has decreased after an initial range expansion. One such species is the browntail moth Euproctis chrysorrhoea L, which was discovered in the eastern United States in 1897. Its range expanded until 1914; after 1915, however, its range contracted and now it persists in only two isolated coastal locations. Although a biolo...

Inbreeding may lead to morphological malformations in a wide variety of taxa. We used genetic markers to evaluate whether malformed urodeles were more inbred and/or had less genetic diversity than normal salamanders. We captured 687 adult and 1,259 larval tiger salamanders (Ambystoma tigrinum tigrinum), assessed each individual for gross malformations, and surveyed genetic variation among malfo...

Malaria and filariases are prevalent in Sudan and their control depends largely on preventive measures against mosquito vectors. The present work aimed to investigate the larvicidal, adults emergence inhibition and oviposition deterrent effects of aqueous extracts from leaves of Ricinus communis L. against the mosquitoes, Anopheles arabiensis and Culex quinquefasciatus as a biological control m...

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...

This note is a further instalment on the antimalarial work which is being carried out on the Travancore Tea Companies' estates in the Vandiperiyar Valley. Reference should be made to the previous paper on this subject (Clemesha and Moore, 1930). Those familiar with this paper will remember that careful anti-malarial measures, both anti-larval and anti-gametocyte, have been going on for a period...

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...

The immature stages of the Clouded Apollo (Parnassius mnemosyne) are assumed to be thermophilic due to the possible time limitations and variable weather conditions during their development. Thus, the degree of canopy coverage may affect habitat use by the species. We explored the spatial distribution of larvae and the development time of pupae under variable canopy coverage conditions. Larvae ...
