Changes in morphology and chemistry of leaf surface in response to herbivore damage may increase plant resistance to subsequent herbivore attack; however, there is lack of studies on induced responses of glandular trichomes and their exudates in woody plants and on effects of these changes on herbivores. We studied delayed induced responses in leaf surface traits of five clones of silver birch ...
In 2008-2009, we reared small ceraphronids (about 0.5 mm in body length) from cocoons that had been made possibly by two acarivorous species, Feltiella acarisuga (Vallot) and Feltiella acarivora (Zehntner) (Diptera: Cecidomyiidae) in Okinawa, Japan. Detailed morphological observation revealed that the ceraphronid was a new species of Aphanogmus Thomson (Hymenoptera: Ceraphronidae). We describe ...
Background and purpose: Çonsidering the role of mite in causing severe allergic reactions in sensitive individuals, particularly women, a study was done to determine the effects of mites in residents of sari township in 1999-2000 Materials and methods: This was a desciptive study done on the residens in sari.

Prevalence of endo and ecto-parasites in cows and buffaloes were investigated in Quetta city, Pakistan. A total of 396 livers and gall bladders of cows and 340 of buffaloes were selected randomly. Overall prevalence of liver parasites in cows and buffaloes was 45.70 and 37.05%, respectively. The species found in livers of cows were: Fasciola hepatica (16.16%), Fasciola gigantica (12.37%), Param...
The organization of gall on the ovary ofSesamum indicum L induced by the gall midge, Asphondylia sesami Felt, not only affects biochemical equilibrium of the host but also causes disturbed vegetative growth and reduced seed-setting. The toxicity created by the gall maker induces the re-orientation of vasculature Cecidogenetic stimuli lead to excessive hypertrophy and hyperplasy forming the gall...
Background: Gall stone is an important health problem in the world for which different risk factors have been characterized. Gall stone and cardiovascular disease have common risk factors. Homocysteine is accepted as one of the risk factors for cardiovascular disease. We aimed to study the effect of homocysteine level on gall stone formation. Methods: 54 patients with gall stone-related disease...
The formation of gall is one of the various types of vegetarianism, and gall producing insects cause stress in their hosts. The present study aimed to investigate the changes of some biochemical and photosynthetic indices due to the gall in Persian oak trees in Forests of Middle Zagros. Sampling was performed from trees infected by gall and healthy trees in Blouran forests. The results showed t...
