Oleander scale, Aspidioutus nerii Bouché, occurred on leaves, and latania scale, Hemiberlesia lataniae (Signoret), inhabited leaves and branches of acacia, Acacia cyanophylla Lindley. We applied regression analysis to explore effects of different host stages, age phases, and species on the numerical responses of the mite to changing scale densities. Our data demonstrate the existence of host-specific numerical responses. The mite responded faster to the density of latania scale than to the density of oleander scale. The numerical responses were faster for ovipositing scale females than for young females. The strength of mite response to the density of the various scale stages, phases, and species was correlated positively with their suitability for the mite. The numerical response of the mite to changes in its host density acted mainly through aggregation or improved survival rather than by enhanced fecundity. © 1996 Entomological Society of America Population Ecology nationallicence Hemisarcoptes nationallicence host effect nationallicence numerical response nationallicence parasitization nationallicence Izraylevich Sergey Department of Entomology, The Hebrew University of Jerusalem, Rehovot 76100, Israel aut Gerson Uri Department of Entomology, The Hebrew University of Jerusalem, Rehovot 76100, Israel aut Hasson Oren Department of Entomology, The Hebrew University of Jerusalem, Rehovot 76100, Israel aut Environmental Entomology Oxford University Press 25/2(1996-04-01), 390-395 0046-225X 25:2<390 1996 25 ee https://doi.org/10.1093/ee/25.2.390 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/ee/25.2.390 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Izraylevich Sergey Department of Entomology, The Hebrew University of Jerusalem, Rehovot 76100, Israel aut NATIONALLICENCE 700 1- Gerson Uri Department of Entomology, The Hebrew University of Jerusalem, Rehovot 76100, Israel aut NATIONALLICENCE 700 1- Hasson Oren Department of Entomology, The Hebrew University of Jerusalem, Rehovot 76100, Israel aut NATIONALLICENCE 773 0- Environmental Entomology Oxford University Press 25/2(1996-04-01), 390-395 0046-225X 25:2<390 1996 25 ee Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
