Influence of food on the growth, development and hibernation of Large White Butterfly (Pieris brassicae)
The abundance of Large White Butterfly (LWB), Pieris brassicae fluctuates from year to year, and a peak in the population is reached in every five to seven years, after which there occurs an abruptExpand

Reverse osmosis and nanofiltration of biologically treated leachate
Experiments of nano-filtration (NF) and reverse osmosis (RO) were conducted to remove most pollutants from the biological treated leachate. For example, the purified permeate after reverse osmosisExpand

Abdominal movements, heartbeats and gas exchange in pupae of the Colorado potato beetle, Leptinotarsa decemlineata
The rhythms of abdominal movements, heartbeats and gas exchange in the pupae of Leptiontarsa decemlineata (Say) were recorded simultaneously using an electrolytic respirometer and infrared gasExpand

Periodic muscular activity and its possible functions in pupae of Tenebrio molitor
Abstract. During pupal development, Tenebrio molitor L. show regular periods of rhythmic muscular contractions and associated body movements. These periods of activity last 2.5‐5.8 min and are moreExpand

Rhythms of passive and active ventilation, and circulation recorded in diapausing pupae of Mamestra brassicae using constant volume respirometry
Abstract The periodically occurring convective inflow of air into the tracheal system, or passive suction ventilation, together with the cyclic bursts of release of CO2 and active ventilation, isExpand

Physiology of diapause in pupae of Pieris brassicae L. (Lepidoptera: Pieridae)
Respiration patterns, water loss and heart activity were investigated during the first three months of diapause in non-acclimated pupae of Pieris brassicae. To observe and record diverse eventsExpand

Diversity in gas exchange and muscular activity patterns in insects studied by a respirometer‐actograph
Different events in insect gas exchange and muscular activity are described by a new system of automatic respirometers, a differential electrolytic microrespirometer‐actograph. This is very sensitiveExpand

Sublethal effects of kaolin and the biopesticides Prestop-Mix and BotaniGard on metabolic rate, water loss and longevity in bumble bees (Bombus terrestris)
Kaolin is an inert material with a broad range of applications, e.g. as an insecticide and as a filling substance in the formulation of biopesticides. Hence, bees that dispense biopesticides to theExpand
