AbstractAlate aphids were sampled in five fields of commercial blueberry, Vaccinium corymbosum L. (Ericaceae), during 2001 and 2002 using yellow tile, green tile, and Tremclad® yellow water traps. Eighty-seven species were identified among a total of 7722 alatae. Several of the species are known virus vectors, including Aphis fabae Scopoli, Brachycaudus helichrysi (Kaltenbach), Hyalopterus pruni (Geoffroy), Hyperomyzus lactucae (L.), Myzus persicae (Sulzer), Rhopalosiphoninus staphyleae (Koch), and Rhopalosiphum padi (L.). The number of species caught varied with year, and the number of species and the total number of alatae varied with field, trap colour, and season. More species were caught in 2001 than in 2002, in yellow than in green traps, and in the summer than in the spring or the autumn, and more alatae were caught in Tremclad® yellow traps than in yellow or green tile traps, and in the autumn than in the spring or the summer. However, numerous interactions limit generalizations. Analyses of the data for individual species revealed similar patterns and interactions. The effects of year, field, trap colour, and season varied with species. Given nonpersistent virus transmission and the large numbers of alatae caught of species that are known virus vectors, there is considerable potential for spread of Blueberry scorch virus by migrant aphids. Field- or area-specific and season-specific control strategies could be developed once the virus vector status of the different species is known. In addition, given the number of significant interactions observed in the data, there is a need to investigate alternative, generalized approaches to reducing virus transmission rates, such as applying whitewash or kaolin particle film to blueberry leaves.

scholarly journals Red trap colour of the carnivorous plant Drosera rotundifolia does not serve a prey attraction or camouflage function

Prey Attraction

The traps of many carnivorous plants are red in colour. This has been widely hypothesized to serve a prey attraction function; colour has also been hypothesized to function as camouflage, preventing prey avoidance. We tested these two hypotheses in situ for the carnivorous plant Drosera rotundifolia . We conducted three separate studies: (i) prey attraction to artificial traps to isolate the influence of colour; (ii) prey attraction to artificial traps on artificial backgrounds to control the degree of contrast and (iii) observation of prey capture by D. rotundifolia to determine the effects of colour on prey capture. Prey were not attracted to green traps and were deterred from red traps. There was no evidence that camouflaged traps caught more prey. For D. rotundifolia , there was a relationship between trap colour and prey capture. However, trap colour may be confounded with other leaf traits. Thus, we conclude that for D. rotundifolia , red trap colour does not serve a prey attraction or camouflage function.

Field experiments to evaluate four different coloured sticky traps for monitoring beneficial insects were conducted on Braeburn apple blocks in four commercial orchards situated in the Motueka region Traps used were white yellow and blue Corflute sheets and a clear Mylar sheet all coated on one side with adhesive (Tactrap) The sticky traps were deployed between 27 February and 24 March 2006 Each colour sticky trap was hung vertically from a branch within the tree and traps were replaced and rerandomised two times during the trapping period Beneficial insects monitored included Aphelinus mali Platygaster demades Anagrus sp Stethorus bifidus and Encarsia spp Results indicated that yellow was the best trap colour for catching A mali Stethorus and Encarsia and a clear trap was best for Anagrus sp Trap colour did not have a significant impact on the catch of P demades

Trap Colour

Large-scale trapping of sheep blowflies (Diptera: Calliphoridae) was undertaken on a mixed farming property in the north of the North Island of New Zealand over 3 consecutive summers. Traps were placed at a density of 1 trap110 ha and baited with fresh sheep offal every 2 weeks. No insecticide was used in the 150-L traps. The most effective bait trialled was sheep offal <2 weeks old. There was no significant effect of trap colour or trap site on the number of blowflies caught. A 95% decline in the principal flystike blowfly, Lucilia cuprina, was recorded. Flystrike incidence at the site was low during the study so that the effect of trapping on sheep myiasis could not be determined.
