Seyfollahi, F., Esfandiari, M., Mossadegh, M.S., & Rasekh, A. 2019 Functional Response of Hyperaspis polita (Coleoptera, Coccinellidae) to the Recently Invaded Mealybug Phenacoccus solenopsis (Hemiptera, Pseudococcidae). Neotropical Entomology doi.org/10.1007/S13744-018-0666-8
Notes: Hyperaspis polita Weise is the major predator of Phenacoccus solenopsis Tinsley in southwestern Iran. The functional response of fourth instar larva, adult female and male of the ladybird, H. polita, preying upon different stages of the mealybug P. solenopsis was evaluated. According to these results, the feeding potential of H. polita is noticeable with the fourth larval instar stage being considered the most efficient predatory stage for use in biological control programs.
