Scientific evidence for the "feeding response" and "masking" effect of smoke

edit

There are three scientific sources that I could find

1) "Engorging of Honey by Worker Honeybees when their Colony is Smoked", J. B. Free, Journal of Apicultural Research ,Published online: 24 Mar 2015

2) David C. Newton, 1968, "Behavioural Response of Honeybees to Colony Disturbance by Smoke. I. Engorging Behaviour", Journal of Apicultural Research, Vol. 7 , Iss. 1,1968 "Experiments showed that engorging behaviour is released among the members of a honeybee colony when they are stimulated by smoke, or by vibration caused by a falling weight. The number of bees engorging is greatest during dearth conditions and unfavourable flying weather. Engorging reaches a maximum about two minutes after a colony is disturbed. An engorging reaction increases the probability of colony survival after destruction of its combs; the implications of this are discussed".

3) "Alarm pheromone perception in honey bees is decreased by smoke" (Hymenoptera: Apidae) [1995] Visscher, P.K. (University of California, Riverside, CA.) Vetter, R.S. Robinson, G.E. 124.148.234.172 (talk) 12:19, 21 October 2016 (UTC)Reply
