The Possibilities of Six-toothed Bark Beetle (Pityogenes chalcographus L.) (Coleoptera: Scolytinae) Sex Identification Based on Adultsâ€™ Biometric Characteristic
Keywords:Picea abies, bark beetles, insect fresh weight, insect dry weight, insect volume weighted index, sex identification
Â The aim of presented study was to determine a basic biometric parameters, such as weight and volume of male and female adults of the six-toothed bark beetle (Pityogenes chalcographus L., 1761) (Coleoptera: Scolytinae), captured to pheromone traps. It was shown that females of the six-toothed bark beetle were statistically heavier than males. Similarly, the volume of the examined insects was generally greater in the case of females, but the difference in this parameter was statistically insignificant within the weight classes distinguished for the analyzed beetles.
