Partial defoliation of spruce by the green spruce aphid Elatobium abietinum (Walker) is a recurrent event in European and, increasingly, North American forests. The patterns of insect abundance on trees have never been satisfactorily described by a n

The pine aphid, Cinara pinea, overwinters as eggs situated on the current year's needles of Pinus species, especially P. sylvestris. The eggs are sparsely distributed, with shoots seldom having more than one needle bearing one or two eggs. Neverthele

On Scots pine, Cinara pinea aggregates only on those twigs bearing needles developed during both the current and previous year (shoots). While some areas of the lower canopy are more heavily colonised than others, the aphids are equally likely to be

In the olive orchards of Granada, Spain, ants are one of the most abundant insect families. Two sites were compared in 1994 and 1995 – a commercial orchard and an abandoned one. In both, the temporal pattern of abundance and the ant species composi

1. Ecologists concerned with life-history strategies of parasitoid wasps have recently focused on interspecific variation in the fraction of the maximum potential lifetime egg complement that is mature when the female emerges into the environment. Sp

This paper outlines a system for the production of common green lacewings in the laboratory, using easily available and inexpensive equipment and producing a healthy surplus of insects for experimental purposes. An economic breakdown of costs is give

Over 10 000 predatory arthropods were collected from two olive orchards, and tested in a serological bioassay for olive moth, Prays oleae (Bernard), predation. The highest number of natural enemies tested positive during the flower generation, when t

Information on parasitoid sex ratio, mutual interference and spatial heterogeneity, obtained from both field and laboratory experiments, was integrated into a model of the interaction between the solitary pteromalid, Cheiropachus quadrum, and the oli

The life-stage mortalities of the bark-beetle pest P. scarabaeoides were studied in a Spanish olive orchard by placing cut logs in the field for adult females to breed. Mortality was found to be greatest at the larval stage with about 25% of the orig

Mortality from parasitism and intraspecific larval competition was measured on a spatial scale for the olive bark beetle, Phloeotribus scarabaeoides, in cut logs within a Spanish olive orchard. Mortality due to parasitism was inversely density-depend
