“…In Canada, bumblebees' activity was 94% greater under standard films than under UV-blocking films (expressed as the number of entrances and exits to and from the hive). No relationship was found there between bumblebees' activity and the amount of solar radiation or the humidity in the greenhouse (Morandin, Laverty, Kevan, Khosla, & Shipp, 2001). The differences between the results from Canada and Israel may be explained by the differences in sun light intensities and temperatures between these two locations.…”

“…These populations show a high degree of colour variation , and genetic studies by Estoup et al (1996) and Widmer et al (1998) (Morandin et al 2001) and more importantly new queens (gynes) and males (Goulson et al 2002a) escape from the glasshouses where they are used as crop pollinators. Furthermore, evidence points to the fact that B. terrestris is able to naturalise easily, even with limited numbers of founding queens (Buttermore et al 1998).…”

Bumblebees, humble pollinators or assiduous invaders? A population comparison of foraging performance in Bombus terrestris

2005

Worldwide trade in non-native bumblebees remains largely unrestricted despite well-documented cases where introductions of non-native bees have gone dramatically wrong. Within Europe, indiscriminate importation of non-native populations of bumblebees (Bombus terrestris) for the pollination of glasshouse crops continues on a massive scale. However, no risk assessment has been conducted for these introductions, perhaps because B. terrestris is considered a native species, so shipping populations from one region to another has been implicitly assumed to present no risk. This view is clearly unjustified because Bombus terrestris populations differ significantly in their genetic makeup as demonstrated by strong differences in coat colour and behavioural traits. Therefore, for the first time we compare an important competitive trait, namely foraging performance, between commercially available B. terrestris populations in contrasting environments. We test whether commercially reared populations differ in their nectar foraging performance and whether this is influenced by both their source environment and the one they are introduced into. We do this by means of a reciprocal transplant experiment. Strong, consistent inter-population differences in performance occurred irrespective of test location: Canary Island bees (B. t. canariensis) were superior to Sardinian bees (B. t. sassaricus), which were generally superior to mainland European bees (B. t. terrestris). These inter-population differences in performance were largely explained by inter-population variation in forager size, with larger bees being superior foragers. However, even when body size was accounted for, "native" bees were not superior to transplanted non-native bees in all but one case. We conclude that non-native populations, especially those with large foragers, can be highly competitive foragers. This could lead to their establishment and displacement of native bees. Therefore, we recommend that unregulated movements of non-native B. terrestris populations within Europe should not be carried out without a full risk assessment.

“…Lack of UV causes a significant reduction of bumble bees (Bombus impatiens) activity and reduction of the colony's growth rate in tomato greenhouses, as well as escaping through gutter ventilation systems (Morandin et al, 2001). Usually a 4-9 days delay of bumble bees' (Bombus terrestris) activity occurs when used in tomato greenhouses that are covered with UV-absorbing plastic sheets.…”

The Effect of UV-absorbing Plastic Sheet on the Attraction and Host Location Ability of Three Parasitoids: Aphidius colemani, Diglyphus isaea and Eretmocerus mundus

The effect of ultra violet (UV)-absorbing plastic sheets on the host location ability of three commercially available parasitoids Aphidius colemani Viereck (Hymenoptera: Braconidae), Diglyphus isaea Walker (Hymenoptera: Eulophidae) and Eretmocerus mundus Mercet (Hymenoptera: Aphelinidae) -was tested in the laboratory and in field trials. The parasitoids' preference between natural light and UV-filtered light was tested under laboratory conditions in a Y-shaped pipe system. The vast majority of all three species were strongly attracted to non-UV-filtered light. In field trials parasitoid's ability to locate a host-infested plant from a distance (approximately 10 m.) was tested. Host location by A. colemani and D. isaea, expressed by parasitization rates, was not affected by greenhouse covering plastic type (regular versus UV-absorbing plastic). E. mundus, on the other hand, was unable to locate the host-infested plant when the latter was placed in the center of the UV-absorbing plastic covered greenhouses. When the host-infested plants were located in the corners of the greenhouses and the wasps were released at the center, the parasitization rates were lower under the UV-absorbing plastic than under the regular plastic covered greenhouses. The significance of UV light to E. mundus host location process and the practical implications it has on the parasitoid's application in the field are discussed.
