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
The migration syndrome in the African armyworm moth, Spodoptera exempts: allocation of resources to flight and reproduction
Physiological Entomology - Tập 18 Số 2 - Trang 149-159 - 1993
Alan Gunn, A. G. Gatehouse
Abstract. Selection for the capacity for prolonged tethered flight in Spodoptera exempta resulted in heavier moths, with significantly larger abdominal glyceride glycerol contents in females of two flight‐selected strains (87% and 49% higher than in the comparable non‐selected strain) and in males of one of them (80% higher). All flight‐se...... hiện toàn bộ
Lesions in haematophagous flies after feeding on rabbits immunized with fly tissues
Physiological Entomology - Tập 1 Số 1 - Trang 55-59 - 1976
Yosef Schlein, Clive J. Lewis
Abstract Stomoxys calcitrans were fed on rabbits previously immunized with various of the fly's tissues. Mortality after 15 days of daily feeding on rabbits immunized with flight muscle proteins was twice that of the control flies fed on an untreated rabbit. Other effects included paralysis of the legs, unequal deposition of the endocutic...... hiện toàn bộ
Thermal response and reversibility of diapause in the eggs of Locusta migratoria
Physiological Entomology - Tập 18 Số 1 - Trang 1-6 - 1993
Yukio Ando
Abstract. Eggs of a local population of Locusta migratoria L. (Orthoptera: Acrididae) collected near Hirosaki (40.5oN) entered diapause when incubated at temperatures between 20 and 35oC. For diapause development the optimum temperature was 10oC. The lower thermal threshold for...... 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
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
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
