“…Both sites were sampled at 15 day intervals from April to November using a white beating tray (Mills, 2005;Speight, 2005) measuring 60 × 50 cm. On each sampling occasion 30 trees were checked, one branch on each of the four aspects of the trees (120 branches per sample) was beaten at each experimental site.…”

Abstract. Species in the carnea complex of the common green lacewing are predators of the common pistachio psylla, Agonoscena pistaciae in both cultivated pistachio plantations and on wild pistachio plants in Iran. The seasonal occurrence of common green lacewings was monitored in pistachio orchards from 2007 to 2008. In addition, the effect of different temperature regimes on preimaginal development, survival and prey consumption of the predatory lacewing Chrysoperla lucasina fed on A. pistaciae nymphs were studied under controlled conditions. The adults of common green lacewings first appeared on pistachio trees in mid April and were most abundant in early July, decreased in abundance in summer and increased again in October. The relative density of common green lacewings was higher in pistachio orchards where the ground was covered with herbaceous weeds than in those without weeds. In the laboratory females of C. lucasina laid an average of 1085 eggs over 60 days at 22.5°C. The maximum prey consumption occurred at 35°C when the larvae consumed 1812 fourth instar psyllid nymphs during their larval period. The intrinsic rate of natural increase (rm) was 0.11. The total development (egg-adult) required 385 degree-days above the theoretical lower developmental threshold of 9.6°C.

“…However, despite their importance, their populations are difÞcult to quantify. The presence of most scale insects is readily observed on the plant surface in the form of galls or wax secretions, but the quantiÞcation of the insects is often complicated by their small size and the propensity for groups of them to remain concealed beneath the plant tissue or wax secretion (Speight 2005). Sampling methodologies for scale insects may be intended to provide whole plant assessments of bark-infesting scale species such as the balsam wooly adelgid, Adelges piceae (Ratzeburg) (Hemiptera: Adelgidae) (Amman 1969) or may be based on counting readily observable galls including those of the Cooley spruce gall adelgid, Adelges cooleyi (Gillette) (Lasota and Shetlar 1986) and the eastern spruce gall adelgid, Adelges abietis L. (Fidgen et al 1994).…”

Beech scale, Cryptococcus fagisuga Lindinger, is a non-native invasive insect associated with beech bark disease. A quantitative method of measuring viable scale density at the levels of the individual tree and localized bark patches was developed. Bark patches (10 cm(2)) were removed at 0, 1, and 2 m above the ground and at the four cardinal directions from 13 trees in northern New York and 12 trees in northern Michigan. Digital photographs of each patch were made, and the wax mass area was measured from two random 1-cm(2) subsamples on each bark patch using image analysis software. Viable scale insects were counted after removing the wax under a dissecting microscope. Separate regression analyses at the whole tree level for the New York and Michigan sites each showed a strong positive relationship of wax mass area with the number of underlying viable scale insects. The relationships for the New York and Michigan data were not significantly different from each other, and when pooling data from the two sites, there was still a significant positive relationship between wax mass area and the number of scale insects. The relationships between viable scale insects and wax mass area were different at the 0-, 1-, and 2-m sampling heights but do not seem to affect the relationship. This method does not disrupt the insect or its interactions with the host tree.

Se presentan los resultados de diversos muestreos llevados a cabo sobre parcelas cultivadas de pistachero en diferentes localidades de Castilla – La Mancha, en las provincias de Ciudad Real, Cuenca y Toledo. Se han encontrado un total de 8 especies de Curculionidae, de 5 géneros (Brachyderes, Otiorhynchus, Polydrusus, Sitona y Lixus) correspondientes a 2 subfamilias: ENTIMINAE y LIXINAE. Brachyderes marginellus, B. pubescens, Polydrusus subglaber, Otiorhynchus cribricollis y Lixus acicularis se han observado alimentándose de hojas de P. vera y se citan por primera vez sobre esta planta huésped. Polydrusus subglaber y Otiorhynchus cribricollis devoran intensamente sus hojas, por lo que se propone seguir investigando estas dos especies como importantes defoliadores de pistacho en la región. Se aportan datos biológicos y corológicos para las especies encontradas.
