Between late August and early November, the diurnal flight pattern was more varied and generally bimodal, though approx. 42 to 55% of the beetles still flew during the dusk period. During either period of the season, there was very little evidence that any flight occurred during the night.

Regardless of the season, approximately 50% of the beetles were caught at or near the dusk by: The flight activity of three species of Simuliidae was studied in the Eden Valley, Cumberland. The flies were caught using a net mounted on a vehicle, which was driven at 48 km/h along a circuit, consisting of four roads parallel to the River Eden (at distances of , , and km from the river), and the main road at right angles to the river, between the villages of Langwathby .
Diurnality is a form of plant or animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature. Endemic and epidemic phases of bark beetles Irruptive bark beetles are endemic in most forests that they attack. During endemic stages, beetle populations are low and can only overcome defenses in less abundant, stressed trees (Boone etal., ),suchaslightningstruck,diseased, by:

The study was undertaken to determine the seasonal and diurnal flight patterns of scolytid beetles inhabiting a second growth forest of Douglas-fir (Pseudotsuga menziesii (Mirb.)Franco) in western Oregon. Air temperatures, relative humidity, light intensity, and wind velocities were recorded for evaluation of their influence on flight : Gary E.

To minimize attacks, timely removal of these trees is important. This is practiced by clearing of wind throws and sanitation felling. Thus, knowledge about the region-specific flight pattern and voltinism of I. typographus is necessary for efficient pest management.
The diurnal pattern of emergence-flight shifted from season to season (Table 2). In the spring (G2), 64% of the adults were collected from late afternoon to mid-eveningAuthor: Robert Haack.

Key words: bark beetle, phenology, diversity, diurnal, circadian Bark beetles in the genus Hypothenemus (Coleoptera: Curculionidae: Scolytinae: Cryphalini) are common and species rich in tropical and subtropical areas worldwide.
There are 22 spe-cies known from Florida (Johnson et al. unpublished), of which five are thought to be nonnative. Bark beetles are integral components in forest ecosystems and therefore can be viewed as beneficial or detrimental depending on the management objectives.
The major bark beetle species that have histories of causing significant damage to forests in British Columbia are listed in Table 1. Table 1. Major damaging bark beetles of British Columbia. Dispersal by flight is obligatory for bark beetles in the subfamily Scolytinae.
Adult bark beetles must leave the natal host and fly to seek new hosts for brood production. Because of the eruptive nature of some bark beetle populations, dispersal capacity has implications for beetle spread and invasion across the by: 1.
Both unimodal –, and bimodal, flight patterns of bark beetles have been documented. However, all previous studies that report diurnal modality have been short in duration. Mendel et al. sampled for 3-d durations during four points in the flight season.
During the winter season the diurnal pattern was unimodal, whereas during the other three periods, the diurnal pattern Cited by: ambrosia beetles in coniferous forests in western Oregon and found that half of the species flew during daylight hours, whereas the other half had crepuscular patterns of daily flight.

Short durational stability selects for quick colonisation and resource use. The diurnal flight response of the walnut twig beetle, Pityophthorus juglandis Blackman (Coleoptera: Scolytidae), was assessed during two seasonal periods at two sites in northern California.

The European spruce bark beetle Ips typographus L. is one of the major tree-killing bark beetles in Eurasia (Öhrn et al. ). The adults hibernate in forest litter and host trees. Under favourable condi-tions in spring, they search for vulnerable host trees, aggregate by pheromones, burrow through the.
