the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
o t s o 1 Near identical trials conducted concurrently in maize lots in Honduras and Mexico produced similar reults in the pattern of larval mortality of Spodoptera rugiperda following application of a baculovirus or a onventional synthetic insecticide. The highest appliation rates of virus resulted in approximately 40% ortality of S. frugiperda larvae. Virus-induced mortalty decreased with tim...
Expression and Biological Activity of the Cystine Knot Bioinsecticide PA1b (Pea Albumin 1 Subunit b)
The PA1b (Pea Albumin 1, subunit b) peptide is an entomotoxin extract from Legume seeds with lethal activity on several insect pests, such as mosquitoes, some aphids and cereal weevils. This 37 amino-acid cysteine-rich peptide has been, until now, obtained by biochemical purification or chemical synthesis. In this paper, we present our results for the transient production of the peptide in Nico...

Insecticide resistance has been known to be prevalent in several insect species including mosquito. It has become a major problem in vector control programs due to pesticide resistance through detoxification enzymes. The present study aimed to compare between the larvicidal action of some organophosphorus insecticides (fenitrothion, malathion and temephos) commonly used in larval control progra...
Chemical and biological insecticides have been frequently used in sugarcane fields to control insects-pests, including the borer, Diatraea saccharalis. Among products used, those based on chlorantraniliprole Metarhizium anisopliae entomopathogenic fungus, stand out. Euborellia annulipes is an insect of order Dermaptera considered a potential predator borer eggs. This study aimed evaluate direct...
