During a laboratory biological study of a midge, Feltiella acarisuga (Vallot, 1827) (Diptera: Cecidomyiidae), acarivorous on two-spotted spider mites, some ceraphronid specimens were reared from the midge cocoons. A detailed morphological study and comparison with previously known species revealed that the ceraphronid is a new species of Aphanogmus Thomson, 1858 (Hymenoptera: Ceraphronidae). The new species is described as A. feltiellophagus Lotfalizadeh, sp. nov. and compared with closely related species. An identification key for all Aphanogmus species associated with predatory cecidomyiids is provided. As a parasitoid of the pupal stage of Feltiella acarisuga, the potential negative impact of A. feltiellophagus on the biological control of tetranychid mites is discussed.

Soil-dwelling Entomobryomorphan Collembola from the Northeast of Iran were sampled for the first time as part of a biodiversity surveying study with the aim of improving ecosystem conservation. Materials were obtained by sampling in three different ecosystems including forest, rangeland and agricultural fields between 2018 and 2019. The specimens were cleared using either Nesbitt’s fluid or lactic acid and permanent microscopic slides were prepared using Hoyer’s medium. As the result of this study, twenty-nine species belonging to twenty-two genera and five families of the order Entomobryomorpha were identified. Among them, two genera and eight species are recorded for the first time from Iran. The new records are Desoria trispinata (MacGillivray, 1896), Drepanosira hussi Neuherz, 1976, Heteromurtrella sp., Orchesella flavescens (Bourlet, 1839), Willowsia bartkei Stach, 1965, Agrenia sp., and Isotomiella gracilimucronata Rusek, 1981. Micrographs of their important features and a key to the species are also provided.

The common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hem: Aphalaridae) is one of the main and most destructive pests of pistachio orchards in Iran. Chemical control is a widely applied method to manage this pest problem. The intensive use of insecticides has led to the development of resistant populations of the common pistachio psylla. In this research, the activities of detoxifying enzymes (general esterase, glutathione S-transferase and cytochrome P₄₅₀) were assessed against two populations of the common pistachio psylla, and the coccinellid predator, Oenopia conglobata L. (Col: Coccinellidae) in Kerman Province, under treatment of three rational insecticides, namely, acetamiprid, spirotetramat, and hexaflumuron in four concentrations (control, LC₂₅, LC₅₀ and LC₇₅). The results indicated that the activities of detoxifying enzymes were higher in the resistant population of psylla compared to the susceptible one. Esterase was the predominant detoxifying enzyme in the pest and its predator. Based on the results, the activity of detoxifying enzymes were higher at the higher concentrations of the pesticides. Esterase activity was greater in the psyllid populations than the coccinellid predator; which may indicate a higher sensitivity of the lady beetle to insecticides than its prey.
