“…Crawlers of both ' races ' did not survive at 80°F (26.7°C). Gerson and A. Hazan Crossing experiments between UP females and BP males were separately conducted by Schmutterer (1952) and by DeBach & Fisher (1956). Results were consistently unsuccessful, convincing these authors that they were dealing with discrete taxonomic units.…”

Análise Regional da Competição Mediada por Fatores Climáticos entre um Parasitóide e um CoccinelídeoPredador da Cochonilha-da-Espirradeira na Califórnia and a coccinellid predator (Rhysobius lophanthae (Blaisd.) (Coleoptera: Coccinellidae), was examined using a general weather-driven, tri-trophic, physiologically based age-mass structured demographic model. The model is of intermediate complexity and was parameterized using extensive laboratory data and fi eld observations from Albany, CA. Temperature-dependent physiological indices were estimated from the laboratory data and used to scale per capita growth, fecundity and survivorship rates from maximal values in a time varying environment. The tri-trophic model was integrated in a GIS (geographic information system) and the species dynamics examined across years and across the ecological zones of California. Field data and simulation results suggested the coccinellid predator was the most important regulating agent of oleander scale in the mild climate of Albany. However, multiple linear regression analysis of simulation data across all ecological zones of California shows that the parasitoid A. chilensis is the most important agent in suppressing oleander scale densities in warmer climates, while the predator R. lophanthae increases scale density an average of 9.7% across all regions.

“…Gerson & Hazan (1979) reported that uniparental forms in Israel are specific to one host (Pittosporum undulatum Vent., Pittosporaceae) and that biparental forms naturally occur on different host species. Furthermore, DeBach & Fisher (1956) reported that two sympatric populations of these forms were obtained on oleander (Nerium oleander L., Apocynaceae) and English ivy (Hedera helix L., Araliaceae). Schmutterer (1952) has pointed out that uniparental forms could only survive indoors in Germany, while biparental forms could also survive in the natural environment and tolerate frost.…”

“…The development of effective control methods against both forms and the determination of the correct time for applying management methods require that some details on the life cycle are well known. A limited number of studies on the biology of both forms of this scale have been conducted and, in these studies, the rates of reproduction, development and survival of both forms on different conditions and on different hosts were compared (DeBach & Fisher, 1956;Gerson & Hazan, 1979).…”

Aspidiotus nerii Bouché, 1833 (Hemiptera: Diaspididae) is a cosmopolitan pest, mainly found in tropical and subtropical regions. It has been reported from hosts corresponding to more than 100 plant families. Particularly important is the damage caused on lemon and olive trees and ornamental plants such as oleander. It has both biparental and uniparental forms. To investigate the population dynamics of both forms of pest, life tables were constructed under controlled conditions in 2016. The studies were carried out on squash in climatic cabinet adjusted to 25±1ºC, 65±1% RH and 16:8 h L:D photoperiod. At the end of the study, life table parameters of both forms of pest were calculated. Namely intrinsic rate of increase (r), 0.039 and 0.042 d-1 ; finite rate of increase (λ), 1.040 and 1.043 d-1 ; net reproductive rate (R0), 14.07 and 27.19 d-1 ; mean generation time (T), 67.51 and 78.49 d, for biparental and uniparental forms, respectively. R0 and T were statistically significant different between the two populations. Given these differences, it was estimated that the population size of the uniparental form may be 1.9 times higher than the biparental form.
