We conducted this study to determine the chronic effects of Azadirachtin on growth parameters, survival and gill morphology of grass carp [Ctenopharyngodon idella (C. idella)] with an average weight of 11.09±2.3 g. We equally distributed 120 fish between three treatments and a control group, with three replicates each. Sublethal concentrations of p...

The tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most important pests of tomato in many parts of the world. The objective of this work was to evaluate the damage of T. absoluta on ten tomato cultivars under feld conditions. A randomized complete block design was used with three replications. The evaluated char...

The resistance of 11 tomato cultivars (Ps-6515, Berlina, Poolad, Petoprid-5, Zaman, Matin, Golsar, Sandokan-F1, Golshan-616, Sadeen-95 and Sadeen-21) to the tomato moth, Tuta absoluta (Meyrick) (Lepidoptera:Gelechiidae) was investigated under field conditions. A randomized complete block design was used with three replications. Data analysis indica...

The aim of this study was to assess the chronic effects of a bio-pesticide (NeemAzal) on some biochemical parameters of grass carp (Ctenopharyng-odon idella) under laboratory conditions. At first, 96 h LC 50 of the pesticide was determined using probit analysis software and was found to be 0.73 mg L À1 of the active ingredient (azadirach-tin) of th...

The genetic base of sunflower elite lines is very narrow, due to many years of selection and breeding. To broaden the genetic diversity of the cultivated sunflower, in 1995 73 wild sunflower populations were crossed with 3 cultivated lines (Testers), and 219 hybrid offspring’s were evaluated in the field. GCA and SCA effects were computed suggestin...

Seventy-seven wild sunflower accessions from USA were compared in France (Mauguio) for 13 quantitative characters using multivariate methods, including clustering, principal component and canonical discriminate analyzes to assess the patterns of morphological and climatic variation. Geographic and climatic data from their sampled sites such as lati...
