Comparative toxicity of different chemical and biological insecticides against the scale insect Dactylopius opuntiae and their side effects on the predator Cryptolaemus montrouzieri
The contact toxicity of various chemical and biological pesticides for the first and second instar nymphs and adults of the Opuntia cochineal scale insect Dactylopius opuntiae and the predator ladybird Cryptolaemus ...
Phenotypic characterization of Tunisian sheep breeds for resistance to abomasal parasites
The aim of this work is to study the genetic resistance of the Barbarine sheep to GIN infestation. This is a preliminary paper about the phenotypic measurements that were collected and compiled in a single phenotype database. ...
Surface Runoff and Drought Assessment Using Global Water Resources Datasets - from Oum Er Rbia Basin to the Moroccan Country Scale
Precipitation and surface runoff vary strongly in space and time across Morocco. The country’s water management is primarily governed at the basin level, following a decentralized approach. However, in some cases, water ...
Wheat drought-tolerance to enhance food security in Tunisia, birthplace of the Arab Spring
The beginning of the‘Arab Spring’in 2011, a regional revolution which started in the Tunisian city of SidiBouzid in late 2010, occurred in part as a result of drought-triggered high wheat prices, which in the past led ...
Impact of climate change and agricultural practices on irrigation water requirements under Nile delta conditions
Agriculture in Egypt consumes about 80% of the available water resources. With an ever-increasing demand and a relatively fixed supply of fresh water, every drop of water should be treated as a drop of life. Consequently, ...
Modelling farmers' responses to irrigation water policies in Algeria: An economic assessment of volumetric irrigation prices and quotas in the Jijel–Taher irrigated perimeter
In Algeria, the management of water based on a strategy of supply and subsidies continues to be applied even as the resource becomes increasingly scarce. The demand for water in Algeria continues to grow, creating an ...
Development of an efficient regeneration system for bombarded calli from immature embryos of Moroccan durum wheat varieties
One of the biggest obstacles limiting genetic transformation of durum wheat is the lack of an efficient regeneration system for bombarded tissues. Our study aims to optimize culture conditions for regenerating bombarded ...
Effect of supplementation by cactus (Opuntia ficus indica f. inermis) cladodes on reproductive response and some blood metabolites of female goat on pre-mating phase
The objective of this study is to investigate the effect of barley substitution by cactus during pre-mating phase on some reproductive parameters and blood metabolites of goats.
Forty adult goats of local breed were allocated ...
Infestation of small ruminants by the metacestode stage of Taenia hydatigena in slaughterhouse, North East Tunisia
Background: Cysticercus tenuicollis (larvae of Taenia hydatigena) is a frequent cosmopolitan
endoparasite of ruminants. The infestation by this parasite is underestimated
since it is neither zoonotic nor inducing high ...
Estimation of the economic loss due to irrigation water use inefficiency in Tunisia
The main objective of this study is to estimate the total economic loss due to inefficient use of irrigation water in Tunisia. Several approaches have been used for this purpose. The optimal level of water application for ...
