We studied the species composition and abundance of Heteroptera in an oil-bearing rose plantation in the Kazanlak Valley, Southern Bulgaria. Insects were collected using two types of traps – sticky and funnel traps – combined with three types of visual stimuli (fluorescent yellow, transparent and purple). Over a four-month period (June to September 2023), a total of 152 specimens representing 22 species of eight families were collected. Our results indicate that some species are significantly more attracted to certain colours and trap types than to others. Insects belonging to the suborder Heteroptera, are not among the pests causing economic losses in Bulgarian oil-bearing rose production. However, the presence of the invasive pest species, Halyomorpha halys (Stål, 1855), raises concerns about the damage this pest could cause to rose plantations in Bulgaria. Additionally, our findings suggest that the predator Deraeocoris ruber, the most abundant species in the samples, might contribute to aphid population control in the studied agricultural setting. Further research would be beneficial to assess its effectiveness as a biological control agent in oil-bearing rose plantations and other cultivated crops.
