The formation of complexes of trunk insects on irrigated lands in the foothills of the Kopet-dag.
During investigations in 1982-83 in artificial forest plantations and orchards in irrigated lands in the foothills of the Kopet-dag Mts, in the Turkmen SSR, USSR, 18 species of trunk insects were found. Details are given of the host trees of each species. The polyphagous Chrysobothris affinis, Aeolesthes sarta, Cossus cossus and others were typical inhabitants of artificial forest plantings but could easily pass to orchards; they are widespread and becoming dangerous pests. Scolytus multistriatus, Trichoferus campestris [Hesperophanes campestris], Xylotrechus namanganensis and Zeuzera pyrina were found only in forest belts but are also able to develop on fruit trees.
