Varandi HB, Kalashian M, Barari H, Rezaei Taleshi SA. 2018. The diversity of wood-boring beetles caught by different traps in northern forests of Iran. Trop Drylands 2: 65-74. Efficacy of trap types is an important factor for sampling, faunistic survey, evaluation of the population density, seasonal dynamic and monitoring of wood-boring beetles. In the present research, the diversity of Wood-boring beetles (i.e., Buprestidae and Cerambycidae) was studied by using different types of trap (window trap, color pan trap, color sticky trap and Malaise trap) in northern forests of Iran (Mazandaran Province, Iran). Different types of traps employed in five study areas, collected a total of 3120 beetles belonging to 55 species (29 Buprestidae and 26 Cerambycidae). The majority of captured specimens were buprestid beetles (79.87%), while only one-fifth of the specimens were Cerambycidae (20.13%). All of the collected beetle specimens were identified to species's level. One genus (Agrilus spp) and the following five species were the dominant species: Acmaeodera rufoguttata Reitter, Anthaxia hyrcana Kiesenwatter et Kirsch, Anthaxia intermedia Obenberger, Chrysobothris affinis (Fabricius) and Stenoprerus rufus (Linnaeus).

Box tree moth (BTM) Cydalima perspectalis (Walker, 1859) is the most harmful pest of different boxwood species in Europe and Asia including Caspian boxwood Buxus hyrcana in the Hyrcanian forests of Iran. Accessible and effective eco-friendly insecticides are required for the pest control. Thus, susceptibility of 2^nd and 4^th instar larvae of BTM to commercial formulation of Bacillus thuringiensis (Bt), two plant extract formulations, Bio1^® and Matrine^®, and three insect growth regulator (IGR) insecticides, chlorfluazuron, chromafenozide and diflubenzuron were investigated in laboratory bioassay. Except for diflubenzuron, significant mortality of both instar larvae was observed. At the endpoint of the experiments (96 h), 75.2–90% of second and 80–85% of fourth instar larvae had already died, as a result of feeding on leaves treated with the highest concentration of the insecticides. Furthermore, based on Probit analysis, Matrine^® exhibited the highest efficiency (lethal concentration LC₅₀ = 2.87 μL·L^–1) on 2^nd instar larvae and followed by Bio1^® (8.07 μL·L^–1), chlorfluazuron (173.3 μL·L^–1) and Bt (326.3 mg·L^–1). The LC₅₀ of Matrine^® and Bt for 4^th instar larvae were 1.75 μL·L^–1 and 335.8 mg·L^–1, respectively. Our study revealed that Matrine^® and chromafenozide could be alternatively used against BTM in situations where there is a permission and need to use insecticides.

Materials and Methods The material was collected from different parts of Mazandaran province in 2007 and 2008. Traditional collecting methods were used: sweeping on grass vegetations, beating of branches of trees and bushes, trapping using different kinds of traps: sticky traps [Oliver Кавказский энтомол. бюллетень 5(1): 63-© CAUCASIAN ENTOMOLOGICAL BULL. 2009 et al., 2004], color traps [Sakalian, Langourov, 2003], window traps, yellow pan traps [Bellamy, 2000], malaise traps [Matheus, Matheus, 1983]. Some species were reared from field-collected larvae in cages. Data on general distribution, taxonomy and nomenclature are given according to Catalogue. Data on distribution in Iran are taken mainly from some surveys on country's fauna listed in Introduction.
