| Abstract | ||
| Wireworm, the common name for larval click beetle (Coleoptera: Elateridae) are serious soil-dwelling pest of many different crops all around the world. This study was conducted to identify the species that belong to genus Agriotes spp and determine their seasonal abundance by using pheromone traps. This study were carried out in three different fields in the middle of Iraq to identify and determine the seasonal occurrence of Agriotes spp Nine sex pheromone of Agriotes spp were used for each of these species which baited with the specific pheromone from 1/9/2008 – 1/9/2009 in the College of Agriculture –Abu- Graib / provenance of Baghdad and Al Nile /provenance of Babylon, while in Al Radhwania / Baghdad were used during May-June/ 2009. Pheromone lures were replaced every 6 weeks, six Agriotes species: A. proximus, A. sputator, A. obscures, A, brevis, A. ustulatus and A. litigious were caught by Sex pheromone traps in addition to A. lineatus wich was recorded by Al-jorany (under publishing paper). Anew recorded of these species in the middle of Iraq. The most abundant species were A. proximus and A.lineatus. Pheromone traps also showed not presence of two types A.sordidus and A.rufipalpus in all three studid areas in spite of uses special pheromone for both types for a full year. We identify some morphological characteristics of wireworms male to distinguish between agriotes species. The characters are : average of adult length, hair color which covers the body, frontal line (carina)which extend from compound eye to labrem , in addition to rate of length and width of pronotum. The study concludes the importance of pheromones in the detection of insect types in a particular environment and recommended to use other types of pheromones belonging th the same genus to make sure of its existence. | ||
