The Israeli fauna of gall midges (Diptera: Cecidomyiidae) associated with plants of the family Apiaceae consists of three species of Lasioptera and two species of Schizomyia that all appear to be monophagous and univoltine. Lasioptera foeniculi n. sp. and Schizomyia botellus n. sp. are described as new to science. Lasioptera carophila, Lasioptera umbelliferarum and Schizomyia buboniae are redes...

The effect of different sources of nitrate salts (ammonium nitrate, sodium nitrate and potassium nitrate) on nitrate reductase (NR) activity and nitrate reductase expression in the leaves of Foeniculum vulgare seedlings grown in pots containing perlite. Two week old seedlings were treated with 30, 60 and 120 mM aqueous solution of ammonium nitrate, sodium nitrate or potassium nitrate. After 21 ...

It was recently discovered that exposure to small concentrations of the essential oils of sweet fennel (Foeniculum vulgare Mill) or pignut [Hyptis suaveolens (L.) Poit] can be used to control aphids. What is not known is whether these oils also influence honeybee behavior. Experiments using both harnessed and free-flying foragers at concentrations used to control aphids showed that bees readily...

Fennel (Foeniculum vulgare Mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds and medicinal uses. As the wild and cultivated plants are influenced by environmental stresses, the effects of salt (25, 50 and 75 mM NaCl), nitrogen and iron deficiency (0 N, 0.5 N of Hoagland’s solution, 0 Fe and 0.5 Fe of Hoagland’s solution), 2°C cold (2, 3 and 4 h) and drought (3,...
