Background: Nowadays stored–product insect pests are controlled by pesticides and chemical fumigant compounds. The continueous use of chemical pesticides is harmful for non–target creatures specially humans and other mammals. Beside they polluted the environment. Objective: Accoring to the studies, the essential oil of Labiatae plants have insecticidal activity against some pests. In this st...

introduction: the occurrence and activity of mites in stored foods cause a variety of qualitative and quantitative damages, including reduction in the germinating power of the grains, bronchial asthma and allergic skin reactions. among the mites associated with stored products, species of order sarcoptiformes especially some species of astigmatina including the genera acarus, suidasia and tyrop...

Pyrethrins are the most widely used insecticide class in olive groves with organic management. Although there data sets about insect pests of stored products and human parasites developing resistance to pyrethrins, is no information on long-term effect agroecosystems. A field method based experimental induction sublethal effects by means application, monitoring response insects through post-tre...

In insects, perception of chemical stimuli is involved in the acceptance or rejection of food. Gustatory receptors (Grs) that regulate external signals in chemosensory organs have been found in many insects. Tribolium castaneum, a major pest of stored products, possesses over 200 Gr genes. An expanded repertoire of Gr genes appears to be required for diet recognition in species that are general...

Dendranthema indicum (L.) Des Moul. is a perennial herb commonly used as a traditional Chinese medicine for a long time. In this work, we took Dendranthema indicum as a target plant and two stored insects which include Tribolium castaneum and Stegobium paniceum adults as target insects. Essential oil obtained from Dendranthema indicum was analyzed by gas chromatography-mass spectrometry (GC-MS)...

Modernization of the agricultural production system led to a significant increase in annual food intended meet ever-growing consumer demand. In many countries, most grains produced is stored for contingency and regular supply. These grains, general, are directly or indirectly infested by insects, resulting severe grain damages storage losses, thus, causing threat safety security. Although varie...

Few investigations have been made of the species description trend of scale insects. The present study reports the discovery pattern and taxonomic efforts for this group based on global species and a literature dataset. In addition, three asymptotic models (Logistic, Gompertz, and Extreme Value) based on a discovery curve were used to predict the species number of scale insects. Our results sho...

Natural products are stored in plants, animals, and microorganisms, which referred to as "natural sources generating compounds." Strong therapeutic substances developed with the help of medicinal plants. As a source several beneficial secondary metabolites that work plant's defensive system against predators including insects, herbivores have been shown be potentially active chemicals, plant-ba...

Induction of plant volatiles by leaf-chewing caterpillars is well documented. However, there is much less information about volatile induction by insects with different feeding habits. We studied the induction of plant volatiles by a piercing–sucking insect, the western tarnished plant bug Lygus hesperus Knight. Adults of both genders and nymphs of Lygus induced the local emission of a blend of...

Nature has been the source of life-changing and -saving medications for centuries. Aspirin, penicillin and morphine are prime examples of Nature׳s gifts to medicine. These discoveries catalyzed the field of natural product drug discovery which has mostly focused on plants. However, insects have more than twice the number of species and entomotherapy has been in practice for as long as and often...
