This study was carried out to evaluate the diapause intensity in Phytomyza orobanchia Kalt. (Diptera, Agromyzidae) in faba bean fields in Alexandria, Egypt. Several visits were carried out in faba bean seasons of 2021 and 2022 during January, February, March and April (cool to warm temperature) to collect spicks from faba bean fields infested by Or...

Orobanchaceae, is noxious root parasites, in Egypt. Some causing huge economic losses to faba bean fields. So far, there are few detailed reports on the rearing protocols of its biological control agent, Phytomyza Orobanchia Kalt. The effect of food supplements on longevity and egg load in non-ovipositing Broomrape fly Ph.Orobanchia ,is not well kn...

Faba bean Vicia faba L. is a primary source of protein in the diet of masses in Egypt. Broom-rape, Orobanche crenata Forsk (Orobanchaceae), present great threat parasitic weed to some crops in Egypt including faba bean. Egyptian farmers were forced to abandon growing faba bean crops due to O. crenata heavy soil infestation. Several methods have bee...

For many years it has been known that cannibalism is a natural phenomenon in insects and has been documented in many insect orders including Lepidoptera. The present study was conducted to determine cannibalistic behavior amongst same-age 2nd, 4th and 5th instar stages of larval Spodotera frugiperda (FAW), Spodotera littoralis (CLW) or when both ar...

A Field experiment was carried out to evaluate the role of predacious mites, which are associated with Tetranychus spp. infestation on their population of cotton. The susceptibility of three cotton cultivars (Mc Nair 220, Okra leaf and Giza 70) to the infestation by Tetranychus spp. was evaluated. The existence of three predatory mites of Tetranych...

As a consequence of the widespread use of insecticides against insect pests in grain warehouses and in the food industry, insecticide resistance has greatly increased among these species all over the world. Nonetheless, insecticide resistance in stored grain insects in Egypt was little studied. Therefore, our study aimed to forecast infestation ris...

A diatom-based formula (POF) of Peppermint oil (PO), 12.5% (w/w), was prepared and its toxicity was assessed against adults of Tribolium castaneum and Sitophilus oryzae. The toxicity was also compared with the toxicity of either commercial diatom (Celatom®) or PO alone using mixing with food bioassay technique. The POF formula significantly enhance...

Field evaluation of four conventional insecticides and one microbial insecticide against black cutworm (BCW), Agrotis ipsilon, at two locations in cotton during 2008 and 2009 seasons were carried out in this study. Susceptibility of the two field strains compared to the laboratory strain for the five insecticides also was studied in the laboratory....

Keywords Essential oils, solid lipid nanoparticles, alternative pesticides and stored product insects. Abstract: Nano silica was chemically prepared from rice husk and characterized using X-Ray Diffractometer and Electron Dispersive Analysis instruments. The data indicated an amorphous structure with 96.9% of silica. In addition, the synthesized...

The rice weevil, Sitophilus oryzae (Coleoptera: Curculionidae) was collected from El-Behera governorate (EB). The first generation showed reduced susceptibility to deltamethrin and malathion compared with the laboratory susceptible strain (LS). Susceptibility test results (using LS colony as a reference strain) indicated that EB strain has relative...

Toxicity and sub-lethal effects of Emamectin benzoate and IGR 's (lufenuron-flufenoxuron) were evaluated against the 2 nd instar larvae of cotton leafworm, Spodopter alittoralis. The biochemical influences of these agrochemicals with the polyphenol oxidase (PPO) of the treated larvae were investigated (invivo). Emamectin benzoate (LC 50 = 0.007 mg...

Field studies were conducted in two different locations at El-Behira Governorate, in 2013 and 2014 cotton seasons to evaluate some insecticide treatments against cotton leafworm (CLW), Spodoptera littoralis (Boisd.). Glutathione S-transferase (GST) and esterases activities in the CLW larvae from the two locations were compared. Spinetoram (field ra...
