Sexual dimorphism of brown marmorated stink bug

The brown marmorated stink bug is a relatively new member of the Croatian entomofauna, whose biology and ecology are still being researched. species known for its polyphagy invasive, as evidenced by damage to field, vegetable, fruit crops around world. aim this study was determine sexual dimorphism Halyomorpha halys based on phenotypic characters dorsal ventral sides body. Sixty individuals each sex were isolated. Each individual photographed from using digital camera, then forewing hindwing pairs removed, mounted microscope slides, photographed. Photographs side body used measure values length, pronotum width, surface area, surfaces pairs. Differences determined visual inspection. results showed that males females differed statistically in all measurements exhibited female-biased size dimorphism. These traits (larger more powerful physique especially wings) make suitable migratory flight thus responsible rapid expansion population into areas. between sexes have also been noted coloration red pigmentation sternum much pronounced than females, further confirming coloration.
