BACKGROUND Agricultural extension and education play a crucial role in knowledge transfer to farmers. However, extension‐training systems consistently face the challenge of farmers not practically applying the knowledge learned from these courses. This study therefore aimed to identify the underlying components of the inhibitors associated with the...

Azolla (Azolla spp.: Salviniaceae) is an aquatic fern that was introduced to the northern region of Iran with the aim of increasing the fertility of paddy fields, but due to suitable climatic conditions and the absence of natural enemies it became a problem in rice production and a destructive factor in aquatic ecosystems. In recent years, the biol...

Chilo suppressalis is a major pest of rice in most regions of Iran and across the world, resulting in "dead heart" and "white head" damage in rice crops. The present study was conducted as a factorial randomized complete block design in Amol County, Iran, in five repetitions for treatments including "rice cultivar" in two levels of Tarom Mahali and...

The current study aimed to determine antioxidant and detoxifying responses of Chilo suppressalis Walker (Lepidoptera: Crambidae) to Beauveria bassiana (Strains BBRR1, BBAL1, BBLN1, BBLN2), Metarhizium anisopliae and Hirsutella subulata. The interactions of insect humoral immune responses with the entered conidia of entomopathogenic fungi in additio...

Rice breeding with genetic background of Iranian cultivars provides an opportunity to improve these cultivars that have high adaptability to the environment and favorable marketability. Therefore, seven promising lines, orginiated from cross combinations of Iranian and exotic rice genotypes, along with two check varieties including Tarom-Mahali and...

The striped stem borer, Chilo suppressalis (Walker) (Lepidoptera: Crambidae), is an important pest afflicting rice in most rice-growing countries in the world. Deliniating the categories of resistance in rice genotypes under field conditions could be helpful in managment of this pest. Two categories of resistance, antixenosis and antibiosis, were e...

In Iranian rice fields, different varieties of rice are cultivated which are differentially impacted by females of the rice stem borer, Chilo suppressalis. To elucidate the role odours may play in their host plant finding behaviour, female Ch. suppressalis were exposed to four varieties of rice plants and their volatiles in a four-arm olfactometer....

In total 27 species from 10 families Alleculidae (2), Anthicidae (6), Cantharidae (3), Cleridae (2), Elmidae (3), Glaphyridae (4), Elateridae (3), Helophoridae (2), Silphidae (1), and Spercheidae (1) were collected and identified. Zusammenfassung Di...

The biochemical properties of α- and β-glucosidase in salivary glands, alimentary canal and haemolymph of Naranga aenescens larvae, one of the most damaging pests of the rice crop in Iran, were investigated. The specific activity of α-glucosidases were 3.88, 2.74 and 1.58 μmol/min per mg protein in the alimentary canal, salivary glands and haemolym...

According to the importance of none chemical controls based on integrated pest management in the rice fields of Iran, first the field biology of the rice green semi-looper was determined then some experiments were conducted to find entomopathogenic effect of Beauveria bassiana on the larvae of the pest. Cages in dimensions 2×1×1 m were used to rear...

Scarab beetles (Coleoptera: Scarabaeidae) collected in Iranian rice fields and surrounding grasslands Scarab beetles (Coleoptera: Scarabaeidae) comprise a group of species that are present in almost all agro-ecosystems. The fauna of these insects was studied in Iranian rice fields and surrounding grasslands from 2000 to 2005. A total of 18 species...

Darkling beetles (Coleoptera: Tenebrionidae) are one of the most numerous and diverse family of beetles, present in almost all agroecosystems. The fauna of these beneficial insects in chain foods of ecosystems was studied in Iranian rice fields and surrounding grasslands. The results show a to-tal of 21 tenebrionid species of 16 genera including, T...

In a total of 45 species of 22 genera including, Stenocarus, Tychius, Ceutorhynchus, Curculio, Archarius, Coniatus, Donus, Hypera, Limobius, Conorhynchus, Pachycerus, Cleonis, Coniocleonus, Chromoderus, Bothynoderes, Rhinocyllus, Bangasternus, Microlarinus, Eustenopus, Larinus, Lixus, Hypolixus, Otiorhynchus and 5 subfamilies including, Ceutorhynch...

Lacewings (Neuroptera) are the efficient predators of pests in different agroecosystems. In this paper, totally 23 species of 14 genera including, Anisochrysa, Chrysopa, Chrysoperla, Cunctochrysa, Dichochrysa, Mallada, Suarius of family Chrysopidae, Coniopteryx, Hemisemidalis of family Coniopterigidae, Hemerobius, Sympherobius, Wasmaelius of family...

Naranga aenescens L. (Lepidoptera Noctuidae), commonly known as the rice green caterpillar, is one of the most damaging pests of the rice crop in Iran causing extensive defoliation. Study of digestive enzymes is so imperative to reach and apply new pest management technologies. Amylases have an important role in the final stages of carbohydrate dig...

The fauna of ants (Hymenoptera: Formicidae) was studied in rice fields of Northern Iran, Mazandaran province through 2000 until 2006. In a total of 39 species from 17 genera and 3 subfamilies were identified. Of these 34 species and subspecies are new records for the Iranian fauna.

Odonata are considered effective predators to control pest organisms in rice fields. In the rice fields and other sites located in Northern Iran (Mazandaran Province) during 2003-2006, the 30 species from 19 genera and 8 families of Odonata (both suborders Zygoptera and Anisoptera) were collected and evaluated.

Ground beetles (Coleoptera: Carabidae) have an effective role in pest control in rice fields. the fauna of these beneficial insects in the rice fields of Northern Iran (Mazandaran Province) was studied based on sampling (pitfall trap and sweeping net) through 2003-2006. Based on the conducted surveys, 27 species of 19 genera and 12 subfamilies were...
