The effect on predators of the biopesticide based on Beauveria bassiana spores was studied. A high concentration of the pathogen showed adverse effects on the predator (Coccinella undecimpunctata) and its biological aspects: 2, 4 and 8 g/L eliminated

Larvae of Spodoptera littoralis, Spodoptera exigua and nymphs of Aphis craccivora were treated with four compounds, the entomopathogenic fungi (two commercial products Biosect, Biover) and the bacterium (Dipel 2x) and one insecticide (Lannet). These

Studies were carried out to determine the effect of the neem product, suneem oil, at two concentrations 10 and 100 ppm, on the second instar larvae of S. littoralis in the laboratory. Two sets of experiments were carried out, choice and no choice. Re

Further investigations have been made to explore the interaction between the pathogen Bacillus thuringiensis and the parasites and predators associated with the cotton leafworm Spodoptera littoralis. The biology of the parasite Zele chlorophthalma sh

Investigations have been made to throw light on the possible inter-relation between the host insect Spodoptera littoralis, the pathogen Bacillus thuringiensis and parasites or predators. The parasite Microplitis demolitor showed to be affected from c

The egg parasitoid, Trichogramma evanescens Westw. was found to be attracted by certain insect sex pheromones. The two synthetic sex pheromones of Pectinophora gossypiella i.e., Albamy and PMW (NOMATE) showed the highest rate of attractiveness. The s

The persistence of spores of Bacillus thuringiensis in cotton cultivations in Egypt showed an obvious reduction after one day of weathering. The decay in the spores viability is progressively correlated with the time of exposure in the field. The spo

Bacillus thuringiensis Berl. showed an obvious effect in reducing the larval population of the cotton leafworm Spodoptera littoralis (Boisd.) in cotton cultivations when sprayed as “Dipel” at the rate of 500 g/feddan. The egg masses of S. littora

A measure of the viable spore counts of Bacillus thuringiensis (B. t.) preparations at various intervals after spray application in cotton cultivations was carried out during two successive seasons 1980–1981. The mortality of neonate larvae of Spod

The field behaviour and bionomics of the red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier) have been demonstrated. The microclimatic temperature conditions where the insects live were recorded monthly (August–February). The insect lives in
