oa Journal of the Entomological Society of Southern Africa - The automatic collection of mass-reared parasites into consignment boxes, using two light sources
This paper descriptionbes a special arrangement of two light sources which made possible the entirely automatic collection of a mass-reared Braconid parasite, Chelonus texanus Cress., which was emerging in 810 rearing units or boxes stacked in a large room (15 X 20 feet). The emerging parasites flew from the rearing boxes to a cloth collecting screen, where they all crawled up towards a large glass funnel and then passed through it directly into a consignment box. The parasites were collected entirely automatically, without being handled at all, so that there was a great saving in labour, apart from the most important fact that they were very much healthier than parasites collected by sucking them up individually into glass vials, which soon became overcrowded.
