“…This is particularly evident by the fact that the proportion of pine stands burned by large fires was significantly higher than expected. In addition, the mature P. halepensis forest provided a suitable environment for M. josephi outbreaks, which accelerated drying of trees and additional fuel accumulation (Mendel et al 1994). This process, which may last for several decades, increases the flammability of the stands and presumably the probability for extensive fire outbreaks.…”

“…In older plantations, the damage is characterized by drying of branches from the lower to the upper parts of the trees, resulting in drying of the tree crown (Mendel and Liphschitz 1988). High population densities of this pest have been observed in plantations and natural forests of P. halepensis in Israel leading to severe injury in these forests (Mendel et al 1994).…”

It has been suggested that during the past several decades, the frequency and the intensity of wildfires have markedly increased in the Mediterranean basin. We came to assess this postulation in the forested region of Mount Carmel, Israel. This region is characterized by Quercus spp. and Pistacia spp. maquis and has been intensely afforested with Pinus spp. stands since the 1920s. We compiled a GIS-based database of the fires recorded in the region since 1983, in addition to archiving data beginning from the 1940s. The data were collected from land stewardship agencies' archives, fire departments and aerial photographs. Prior to the early 1980s, no systematic documentation of the fires was available, rather just sporadic qualitative documentation of the large forest fires that occurred. Between 1944 and 1982, only 6 large fires were documented, while after that 11 large fires occurred. Analysis indicated that the spatial distribution of the fires does not occur at random, and their locations are significantly closer to roadsides compared to an expected random distribution. The annual number of fires and the areas burned during the last two decades were not correlated with annual precipitation in any manner. Accordingly, we suggest that the increased number of large forest fires during the last decades is associated with the maturation and senescence of the planted forest coupled with increased human activities.

“…Thousands of hectares of Maritime pine, Pinus pinaster , have been killed by Matsucoccus feytaudi Ducasse in South‐eastern France, Corsica and Italy (Covassi & Binazzi, 1992; Riom, 1994; Jactel et al ., 1998). In Israel, large areas of Pinus halepensis are being destroyed by Matsucoccus josephi Bodenheimer et Harpaz (Mendel et al ., 1994), and severe damage of several pine species in North‐eastern U.S.A., China and Japan has been caused by Matsucoccus matsumurae Kuwana (McClure et al ., 1983; McClure, 1989; Kosztarab, 1996; Kishi & Ogura, 1998).…”

1 The effects of pheromone dose, trap size and trap design on the capture of male Matsucoccus feytaudi were studied in maritime pine forests of Portugal, France and Italy, and Matsucoccus josephi in Aleppo pine stands of Israel. 2 Males of both species respond to racemic mixtures of the respective sex pheromone at a dosage as low as 25 mg. However, for low population densities of M. feytaudi, a 50 mg dosage was needed to guarantee male catches significantly different from the control trap. 3 Male capture increased with increasing dosage up to a threshold level for both species. Overdose repellence was not observed even with baits containing 1600 and 2200 mg of the pheromone of M. josephi and M. feytaudi, respectively. 4 For M. feytaudi, a higher dose-response was observed at medium population densities, whereas lesser captures were registered at low and high population densities, suggesting female competition in the latter case. 5 Catches of M. feytaudi males were not affected by trap design, whereas M. josephi males were caught in significantly greater numbers in delta traps. Large traps caught significantly more males of both species. 6 The relative higher male catches in the marginal zone of the sticky traps is probably related to males landing behaviour in the vicinity of the pheromone source. 7 The shape and size of the trap did not affect the bias of the estimates of male catches. However, the plate traps provided higher precision. Both bias and precision improved with increasing dose.

The attraction of several adult predators, genera Elatophilus, Hemerobius and Sympherobius, to the sex pheromones of pine bast scales, Matsucoccus Cockerell, has already been demonstrated. Here, the hypothesis that the larvae of these predators are similarly attracted to the host prey sex pheromone is tested. The response of predators was tested in field trials using pine tree arenas baited with the sex pheromones of M. josephi Bodenheimer & Harpaz, M. feytaudi Ducasse and M. matsumurae Kuwana. Experiments were conducted in Israel in stands of Pinus halepensis infested by M. josephi and in Portugal in stands of P. pinaster infested by M. feytaudi, respectively. The selectivity of larvae for the three sex pheromones was tested in Petri dish arenas in the laboratory. In the field, the larval stages exhibited similar modes of attraction to those of the conspecific adults: Elatophilus hebraicus Pericart in Aleppo pine forest, E. crassicornis Reuter and Hemerobius stigma Stephens in the maritime pine forests. Laboratory choice tests confirmed the kairomonal selectivity of larvae. Both forest and laboratory tests demonstrated the response of a coccinellid of the genus Rhyzobius to the sex pheromones of M. feytaudi and M. matsumurae. A unique chemical communication system among several taxa of predators of Matsucoccus spp. was highlighted that may be attributed to their coevolution on a geological time scale.
