A revision of the genus Isotomurus (Collembola: Isotomidae) in northern Iran using molecular evidence.

Three new species of Isotomurus Börner are described from northern Iran. Status of studied populations is confirmed as new species by using COI and 28SrRNA markers. The new species belong to species-group characterized by 3,3,1 trichobothria on Abd.

Review of the Iranian Parholaspidid mites (Acari: Mesostigmata) with a key to the species.

Six species of Parholaspidid mites were collected from Guilan province in Northern Iran. Gamasholaspis browningi (Bregetova Koroleva, 1960) is a new record for the Iranian Parholaspidid mite fauna. This paper provides a checklist for Parholaspidid mites species recorded from Iran, with a key for identification of the species.

Changes in immune responses, gene expression, and life table parameters of Helicoverpa armigera Hübner fed on a diet containing the saponin of tea plant, Camellia sinensis.

Saponins cause mortality in insects by reducing food absorption and movement in the gut, which may be used to exploit the control of insect pests. In the current study, tea seed saponin (TSS) was extracted and then added to the artificial diets of Helicoverpa armigera. Pre-ovipositional period of the TSS-treated individuals increased while longevity and fecundity decreased compared to control.

Vertagopus (Collembola, Isotomidae) of Iran and Caucasus.

The materials on the genus Vertagopus Börner from the Caucasus and Iran are revised. Two new species, V. persicus sp.

Alterations in some physiological processes of Bactrocera oleae Rossi (Diptera: Tephritidae) following pyridalyl treatment.

Pyridalyl is one of the recently discovered insecticides which has shown toxicity against several insect pests with slight- or non-lethal effects against natural enemies. Cytotoxicity and prevention of protein synthesis have been reported as pyridalyl mode of action. In the current study, adults of Bacterocera oleae, as a major pest of olive, were fed on protein hydrolysate diet containing LC concentration of pyridalyl to determine the possible mode of action through gene expression and amino acid profile.

Changes in immune responses of Helicoverpa armigera Hübner followed by feeding on Knotgrass, Polygonum persicaria agglutinin.

There is no study implying the effect of plant lectins on insect immune elements in both challenged and non-challenged conditions with entomopathogenic agents. Lectins may bind to immune receptors on the surface of insect hemocytes, thus inducing or even disabling common immune functions including hemocyte counts, nodulation/encapsulation, phenoloxidase activity, and synthesis of antimicrobial peptides. In the present study, effect of Polygonum persicaria L.

Effect of Polygonum persicaria (Polygonales: Polygonaceae) Extracted Agglutinin on Life Table and Antioxidant Responses in Helicoverpa armigera (Lepidoptera: Noctuidae) Larvae.

Plant lectins could reduce insect populations by imposing imbalances in biology and physiology. Here, an agglutinin was extracted from Polygonum persicaria L. (PPA; Polygonales: Polygonaceae) and its effects were investigated on life table parameters and antioxidant system of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae).

Two new species of Cosmolaelaps Berlese (Acari:Laelapidae) from Iran .

This paper reports on two species of mites of the genus Cosmolaelaps Berlese, 1903 in Iran--C. dorfakiensis sp. nov.

Two new species and one new record of larvae of the family Johnstonianidae (Acari: Prostigmata) from Iran with a key to species of the genus Diplothrombium.

Diplothrombium sahragardi sp. nov. and Diplothrombium ostovani sp.
