Tephritis alamutensis sp. nov. collected on flowerheads of Cousinia sp. cf. umbrosa (Asteraceae: Cardueae) in northern Iran is described. It is similar to T. ochroptera S. Korneyev, 2013, and T. afrostriata S. Korneyev, 2013 in body size and wing pattern coloration (yellowish body, pale wing pattern, cell r₁ with two large spots and oviscape at least partly yellow), but differs from both species by the incised aculeus tip and setulose ventral side of vein R₄₊₅, as well as details of the wing pattern. The new species is also compared with the superficially similar European species, T. vespertina (Loew, 1844). An improved key to species of Tephritis having the pale brown wing pattern is provided.

The olive fruit fly Bactrocera oleae is one of the most serious and economically damaging insects worldwide, affecting the quality and quantity of both olive oil and table olives. Laboratory bioassays were conducted for the first time to evaluate the susceptibility of B. oleae pupae to two entomopathogenic nematodes (EPN) species, Steinernema carpocapsae and Heterorhabditis bacteriophora. The nematodes tested caused pupal mortality of 62.5% and 40.6%, respectively. The most noteworthy result was obtained with S. carpocapsae which was able to infect 21.9% of the emerged adults. Since this tephritid fly spent several months in the soil as pupa, the use of EPNs could be a promising method to control this pest.

Three species of phytophagous insects were reared from the heads of Arctium minus (Hill.) Bernh: Tephritis bardanae Schrank., Orellia tussilaginis f. (Tephritidae) and Metzneria lappella (L.) (Gelechiidae). They were found to be parasited by two species of Hymenoptera: Bracon minutator (F.) and Habrocytus musaeus (Walk.) Inside the heads of A. minus was found a predator Orius minutus (L.), which probably had developed there.

The degree of damage to Rosa rugosa (THUNB.) fruits by larvae of Aspila tenebrosana DUP. and Rhagoletis alternata (FALL.) in the city area of Lublin was investigated.
