toxic effects of malathion and endosulfan to fertile chicken eggs were determined. in-jection of 1.25, 2.5, 5.0 and 10.0 mg/egg of malathion into yolk sac of fertile eggs prior to incubation caused mortality of 10.0, 30.0, 83.33 and 93.33% respectively. similar trend was observed with injection of endosulfan doses. malathion and endosulfan at 1.25 mg/egg caused no pronounced ld50 increase in mo...
Background and Aim: There are different species of arthropods and rodents in different parts of Iran that are important in terms of medicine and health. To make a proper decision for the control of vectors, it is necessary to have accurate and complete information about the current status of insects control methods for plan and provide appropriate solutions based on it. Therefore, this study ai...
An effective biological control-integrated pest management (BC-IPM) system that maximizes biological control of Plutella xylostella (L.), Artogeia rapae (L.), and Trichoplusia ni Hubner) has been developed. In the first phase, chemical insecticides were replaced by the judicious use of the microbial insecticide Bacillus thuringiensis; there was an immediate reduction (>50%) in the number of tre...
A total of 128 Bacillus cereus-like strains isolated from fresh fruits and vegetables for sale in retail shops in Denmark were characterized. Of these strains, 39% (50/128) were classified as Bacillus thuringiensis on the basis of their content of cry genes determined by PCR or crystal proteins visualized by microscopy. Random amplified polymorphic DNA analysis and plasmid profiling indicated t...
Since their discovery in the late 1980s, neonicotinoid pesticides have become the most widely used class of insecticides worldwide, with large-scale applications ranging from plant protection (crops, vegetables, fruits), veterinary products, and biocides to invertebrate pest control in fish farming. In this review, we address the phenyl-pyrazole fipronil together with neonicotinoids because of ...
“The escalating concern about resistance in C. rosaceana field populations has reinforced the need for continued resistance monitoring and identification of effective tools for integrated pest management programs.” The native North American pest, obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), is widely distributed and has a broad range of over 50 hosts, b...
Following preliminary screening of 13 ethanolic plant extracts, belonging to 10 different families, a total of 11 extracts were subjected to detailed toxicity evaluation against the larval stage of the housefly, Musca domestica L. The larvicidal LC50 values were < 100 ppm for Piper nigrum (50.1 ppm), Azadirachta indica (76.9 ppm), Conyza aegyptiaca (77.0 ppm) and Cichorium intybus (96.8 ppm); r...
Background and purpose: The medical importance of cockroaches is much greater than what has generally been realized. They are known to carry pathogenic viruses and bacteria such as escherichia coli, Staphylococcus aureus and salmonella species including S.typhi and S.typhimurium. As a result, their eradication is very important. Materials and Methods: One of the best and effective ways of ...
Five insecticides (Bifenthrin, Deltamethrin, Etofenprox, Permethrin and Lamda cyhalothrin) recommended by WHO, at their recommended dose were compared for their efficacy and wash resistance through bioassay against mosquito vectors, Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi. Etofenprox treated nettings exhibited better knockdown and mortality than the other insecticides. The...
Background: The German cockroach (Blatella germanica) is one of the most important vectors of public health interest due to its involvement in the transmission of infectious diseases. Different insecticides are used to control cockroaches; however, resistance developed against most of insecticides has made them ineffective. Attempts should always be made to find proper alternat...
