“…Extreme temperatures, both hot and cold, have also been shown to restrict foraging in social insects (e.g. Potter, 1964;Marsh, 1985;Kleinert-Giovannini and ImperatrizFonseca, 1986;Salman et al, 1988). In ants, ground temperature and the availability of thermal refuges can be crucial (e.g.…”

Environmental factors influencing daily foraging activity of Vespula germanica (Hymenoptera, Vespidae) in Mediterranean Australia

In social insects, workers forego reproduction in favour of foraging and other tasks to promote growth of the whole colony. Maximising individual work effort is limited by the physical constraints on foraging outside the nest. Previous studies of factors influencing activity in social insects suggest that light intensity, ground and air temperature, relative humidity, solar radiation, wind speed and/or rainfall may be important. This study aimed to determine which environmental factors influence foraging in an invasive social insect, Vespula germanica, which has been introduced to Australia, where it experiences a hotter and drier climate than in its native range. Activity was measured in terms of foraging traffic, with nests from a range of locations being monitored. Results indicate that the onset of rain reduces activity by approximately 30 %, but foraging returns to previous levels immediately after rain stops. Foraging time is correlated with duration of daylight, with wasp daily activity being on average 22 min longer than the time between sunrise and sunset. Low light was found to restrict wasp activity, as were low and high temperatures. A linear mixed-effects model developed to explain the influence of these variables on numbers of foragers was highly significant. Under hot conditions, V. germanica individuals thermoregulate their body temperature by regurgitating water. They also use water in evaporative cooling to keep nests at optimum temperatures. Thus, in this species, hot temperatures increase the need for water, and so populations may be severely impacted in seasonally hot regions where water is limited.

“…Often, an invasive species adapts to its new environment, and understanding how the invader and the invaded environment interact is necessary to develop and revise control methods (Salman et al, 1988). This knowledge may also aid in assessing the impact the species has on the invaded community.…”

“…Termite food consumption varies according to species and natural food (Nel and Hewitt, 1969). Toilet paper roll baits, litter bags, wooden baits, wooden stake baits and corrugated cardboard or Grass bags are used to measure the relative consumption of different species of termites according to La Fage, et al 1973;Brian, 1978;Said, 1979;Ali, et al 1982;Abdel-Wahab, et al 1983;Salman, et al 1987;El-Sebay, 1991 andEl-Sherif, et al 2009. Different forms of traps are also used to monitor foraging activity of many groups of termites such as Polyvinylchloride (PVC) collars trap, glass plates, squares or rolls trap of corrugated cardboard (El-Sebay, 1991;Su, et al 1991;Ahmed, 1997;El-Sherif, et al 2009 andAbd El-Latif, 2013).…”

This study was carried out at El-kasasien district, Ismailia governorate from April 2013 until July 2013 to evaluate the efficiency of three shapes of termite traps and also from September 2013 until November 2013 to evaluate the efficiency of five trapping materials for the subterranean harvester termites Anacanthotermes ochraceus (Burm.). Results showed that food consumption varied with trap shape though food consumption was almost similar throughout four months. The most efficiency was the plastic trap followed by the corrugated card board trap, while the least was the P.V.C trap. Significant differences were found, where the mean values of food consumption were 18.29, 14.08, and 6.46 g/ trap, with mean numbers of captured termites of 11.18, 6.83, and 4.32 individuals/ trap, respectively.The highest food consumption, soil translocation and number of captured termites occurred in corrugated cardboard material used for trapping followed by cellulose, toilet papers, and wooden particles, while the lowest consumption wooden stakes. Significant differences were found between cardboard and cellulose and between toilet paper, wooden particles and wooden stakes.

“…Soldiers are found all over the year with their number positively correlated with the total number of all different forms. Salman et al (1987), found that the foraging activity of sand termites, Psammotermes hypostoma (Desn.) was high during spring and summer and low during winter foraging activity was reduced immediately after swarming.…”

“…activity were attributed to the meteorological variables, the mini., relative humidity seems to be the most effective variable followed by the maximum temperature. Salman et al (1987), in Egypt, stated that, the climatic variation (mini., and max., air temperature) at 5 cm above the soil surface accounted for 73% of the termite activity of P. hybostoma, with mini., air temperature having the greatest effect.…”

This work conducted in Sharkia Governorate, data showed that, the highest number of foraged workers of Anacanthotermes ochraceus (Burm), was found during spring and autumn, 2014, and the lowest was occurred in summer season, the numbers begun increased gradually in January, February, March, April and May, then decreased in Jun, July and August. Workers caste represented (77.73% of total colony). Nymphs showed that, the largest number occurred during autumn, and the least was occurred in summer, begun increased in Jan., February, March, April and May, then decreased in Jun-July and Nov-Dec. Nymphs represented (13.36% of total colony). Soldiers caste were highest during autumn in Sept., then decreased during winter in Nov.-Feb., and began to rise again during March, April and May, while the least number occurred during summer in June-July. Soldiers represented (7.29% of total colony), and showed highly rates correlated with the swarmers and the various forms. Swarmers or "alates" were found highly during April and Oct., and the lowest rate occurred in Feb. Crowds of swarmers appeared twice during the year in February, March, April and May, then disappeared and reappeared again in Sept., Oct. and Nov., the swarming were found in spring and autumn seasons and represented (1.69 % of total colony). Termite castes were abundant in two periods/year in spring and autumn when max., temperature of soil temperature ranged between (25-35ºC), the mini., soil temperature ranged between (13-27ºC), the rainfall were (0.0, 33.0 and 97.6 m 3 /Inch 2), and the relative humidity higher than (70%), while castes were lower in summer and winter seasons when soil max., temperature were less than (25 ºC) and higher than (35 ºC), the mini., temperature ranged between (8-26 ºC), the rainfall higher than (100 m 3 /Inch 2), and the relative humidity less than (70%). Crowds of swarmers avoid time rainfall and appeared profusely in the periods after the rain when the weather is warm and the soil is moist, the homeowners begun to see winged termites emerge in large numbers inside their home on the soil surface. Statistical analysis showed no significant for tested factors, while were significant with R.H. was the main reason for this effect.
