Past experiments concerned with the elucidation of the daily activity pattern of male spruce budworm, Choristoneura fumiferana (Clem.), have used the response of males to virgin females as the criterion of activity. Males showed a peak response just after sunset and little activity in the early afternoon (Greenbank 1963; Sanders 1971a). Difficulty arises in interpreting such data in terms of male activity patterns. It is obvious that males are active after sunset; however, there is no way of knowing whether the reduced activity in the early afternoon is a result of changing response thresholds by the males or whether it is a result of the females releasing insufficient, if any, pheromone (see Morse et al. 1982). After the identification of the components of the female sex pheromone (Sanders and Weatherston 1976) a synthetic sex attractant was developed and the inherent daily activity pattern of male spruce budworm could be determined.

Abstract The aim of this paper is to characterize the daily activity pattern of the common hamster at two sites with different levels of human impact on environment. Locality no 1, Zesławice, is located within the administrative borders of Krakow agglomeration and is intensively penetrated by people. The farmers spend long periods of time in the fields and do much work manually. Locality no 2, Szczotkowice, is located between the villages of Szczotkowice and Pierocice, in the Działoszyce municipality. Extensive agriculture is carried out in this locality. The farmers use agricultural machines, but for most of the daytime, they are not present in the fields even during the busy harvest season. The daily activity of animals was studied using the method of food tables. The results indicate that hamsters from areas with high level of human pressures started their daily activity two hours later than those from rural areas. They exhibited higher synchronization and more uniform daily activity patterns than was recorded at the typically agricultural site. The morning and evening activity peak was significantly more distinct for urban hamsters than for rural hamsters.

This study compared the microhabitat use, daily activity pattern and diet of Liolaemus etheridgei Laurent 1998 in two Polylepis woodlands: El Simbral (fragmented) and Tuctumpaya (unfragmented), in Arequipa, Southern Peru. In both populations, we did not detect positive selection for any microhabitat; however, the population at El Simbral showed a negative selection for Polylepys trees while the Tuctumpaya population showed negative selection for Polylepis trees and non-thorny bushes. In El Simbral, active individuals were detected between 9:00 and 15:59h, whereas in Tuctumpaya, we detected active individuals from 8:00 to 17:59h. In both populations, observations of active individuals dropped between 11:00 and 11:59h. We recorded 17 and 23 prey categories in the El Simbral and Tuctumpaya populations respectively. The most important animal prey category in each population was found to be Lygaeidae: Hemiptera, and was the only animal prey category that was selected for in El Simbral and Tuctumpaya. In addition, due to the proportions of plant material found, the El Simbral was found to be omnivorous, whereas the Tuctumpaya population was herbivorous. Trophic niche breadth was broader in Tuctumpaya (B_a= 0.202) than the El Simbral (B_a= 0.147) population, despite there being no significant differences in diet (Permanova: F = 1.036, P = 0.409, permutations = 9999), which is coherent with the high value of trophic niche overlap (O_(j,k) = 0.963). Our compiled data reveal that L. etheridgei shows no selection for any of the resources we define in Polylepis woodlands, on the contrary, it selects negatively against Polylepis trees and non-thorny bushes. The daily activity patterns indicate a bimodal pattern with peaks at 9:00-10:59 and 13:00-13:59 h. The diet of L. etheridgei consists mainly of plants (%W: 66.373), and the most important animal prey category is Lygaeidae: Hemiptera (%IRI = 55.3), which is selected positively.

This study describes the daily activity in a simulated high tide situation of four species of hermit crabs (Pagurus criniticornis, Clibanarius antillensis, C. sclopetarius, and C. vittatus) that coexist in an intertidal flat in southeastern Brazil. Observations were done in two-hour intervals during two subsequent days (48 h) in three replicate pools with thirty crabs each. Among species (between and within genera) there was an evident variation in activity patterns, of which three could be distinguished. The circadian activity patterns of C. antillensis and C. vittatus could be characterized as evening and nocturnal, with resting peaks during the morning and afternoon. The circadian activity pattern of C. sclopetarius was characterized by two marked peaks of inactivity, corresponding to dawn and evening, which could represent an intrinsic association with the semi-lunar tidal cycles of the study area. Pagurus criniticornis showed high activity not influenced by day/night conditions during the entire observed period. These activity pattern variations of the studied hermit crabs should be taken into account in designing further experiments. More precise and accurate interspecific behavioral comparisons among species could be achieved in nocturnal experiments, the high activity period of all species.

AbstractRelease rates of synthetic attractant of the spruce budworm, Choristoneura fumiferana (Clem.), from a PVC formulation were determined by weight loss. They varied in direct proportion to the initial concentration of the attractant and also with the size of the pellet. Release rates declined by about 50% over the time intervals of 10–40 days and 40–100 days. Initially they were two to three times lower at 10°C than at 21°C, but were far more constant over time at the lower temperature. A pellet weighing 130 mg containing 42 μg of attractant released an estimated .1–1 μg/day, or 4–40 ng/h, which is close to the rate of emission by a calling female (Silk et al. 1980), and field trapping data showed that a lure this size attracted the same number of males as a calling female.
