Control of ventilatory movements in the aquatic insect Corydalus comutus: central effect of hypoxia
Physiological Entomology - Tập 9 Số 1 - Trang 19-28 - 1984
Sue C. Kinnamon, Ann E. Kammer, A L Kiorpes
ABSTRACT. The influence of hypoxia and hypercapnia on the ventilatory rhythm of the hellgrammite Corydalus cornutus L. (Megaloptera) was studied. In intact animals the frequency of rhythmic retractions and protractions of abdominal gills is increased by hypoxia (10% O2, 90% N2) but no ventilatory response is elicited by hype...... hiện toàn bộ
Vibrational communication of the brown marmorated stink bug (Halyomorpha halys)
Physiological Entomology - Tập 41 Số 3 - Trang 249-259 - 2016
Jernej Polajnar, Lara Maistrello, Bertarella Ambra, Valerio Mazzoni
AbstractCommunication with substrate‐borne vibrational signals is common in the family Pentatomidae, although this aspect of biology of the invasive pestHalyomorpha halysStål remains unexplored so far. In the present study, the behaviour of single animals and pairs is observed on a bean plant and a loudspeaker membrane at the same time as...... hiện toàn bộ
Comparing the effects of five naturally occurring monosaccharide and oligosaccharide sugars on longevity and carbohydrate nutrient levels of a parasitic phorid fly, Pseudacteon tricuspis
Physiological Entomology - Tập 31 Số 1 - Trang 46-56 - 2006
L. Chen, Henry Y. Fadamiro
Abstract.  The longevity and nutrient levels of Pseudacteon tricuspis provided with 1 m solutions of five naturally occurring sugars, fructose, glucose, sucrose, trehalose and melezitose, are compared. All but melezitose, result in significant increases in the longevity of P. tricuspis in compar...... hiện toàn bộ
Effects of sugar feeding on carbohydrate and lipid metabolism in a parasitoid wasp
Physiological Entomology - Tập 25 Số 1 - Trang 17-26 - 2000
Dawn M. Olson, Henry Y. Fadamiro, J.O.nathan G. Lundgren, George E. Heimpel
SummaryLifetime patterns of carbohydrate and lipid metabolism were compared in starved and sucrose‐fed adults of the parasitoid Macrocentrus grandii (Goidanich) (Hymenoptera: Braconidae). As expected, sucrose‐fed individuals lived longer than did starved individuals. Macrocentrus grandii males and females eclose...... hiện toàn bộ
Compensation by locusts for changes in dietary nutrients: behavioural mechanisms
Physiological Entomology - Tập 10 Số 4 - Trang 443-452 - 1985
Stephen J. Simpson, Julie Abisgold
ABSTRACT. The detailed behavioural mechanisms underlying an instance of compensation for changes in dietary nutrients are described for the first time in an insect. Nymphs of Locusta migratoria L. were given one of four artificial diets on the third day of the fifth instar, and their feeding patterns recorded in detail for 12 h. The diets ...... hiện toàn bộ
Desiccation and temperature resistance of the larger grain borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae): pedestals for invasion success?
Physiological Entomology - Tập 46 Số 2 - Trang 157-166 - 2021
Reyard Mutamiswa, Honest Machekano, Charles Singano, Virgil Joseph, Frank Chidawanyika, Casper Nyamukondiwa
AbstractThe larger grain borer, Prostephanus truncatus (Horn) is an invasive insect pest species of global economic concern. It however remains unknown how P. truncatus succeeds under increasing temperatures and desiccation effects associated with projected climate change. Here, we investigated the effects of de...... hiện toàn bộ
Within-generation variation of critical thermal limits in adult Mediterranean and Natal fruit flies Ceratitis capitata and Ceratitis rosa: thermal history affects short-term responses to temperature
Physiological Entomology - Tập 35 Số 3 - Trang 255-264 - 2010
Casper Nyamukondiwa, John S. Terblanche
Pheromones of ants: a review
Physiological Entomology - Tập 4 Số 2 - Trang 161-189 - 1979
Katharina Parry, E. David Morgan
Multicomponent alarm pheromones in the mandibular glands of major workers of the African weaver ant, Oecophylla longinoda
Physiological Entomology - Tập 4 Số 1 - Trang 15-25 - 1979
John W.S. Bradshaw, R. BAKER, P. E. Howse
ABSTRACT. The complex system of alarm communication in Oecophylla longinoda is described. The mandibular gland secretion of major workers releases in other major workers a complex pattern of behaviour, which includes components of alerting, attraction and biting. The main constituents of the secretion are hexanal and 1‐hexanol, which relea...... hiện toàn bộ
Statistical modelling of insect behavioural responses in relation to the chemical composition of test extracts
Physiological Entomology - Tập 26 Số 4 - Trang 381-390 - 2001
Alan Hern, Silvia Dorn
Abstract. The use of generalized linear models (GLM) for relating changes in insect behaviour to changes in the chemical composition of a plant extract is presented and applied to data from an experimental study of the olfactory response of Cydia pomonella L. (Lepidoptera: Tortricidae) to apple volatiles. The volatiles were collected from h...... hiện toàn bộ
