Notes: Population development of cottony scale, Capulinia sp., was studied in July-October 1996 on Psidium guajava, P. friedrichsthalianum and P. guineense species to evaluate host suitability. Psidium spp. were infested with approximately 300 Capulinia sp. eggs per plant. Counts were taken of 1st- and 2nd-instar males and females, 3rd- and 4th-instar males and adult females. All evaluated instars were present in significantly greater numbers on P. guajava. The mean populations were 541.16 on P. guajava, 6.57 on P. friedrichsthalianum and 0.00 on P. guineense. These results suggest a high susceptibility of P. guajava to Capulinia sp. infestation.
