First instar nymphs and adults of the grain aphid Sirobion auenae that had been reared at
10° C and 20° C over a number of generations, were cooled to‐5° C and‐10° C for 1 h and 6 …

Altered temperatures affect insects' life history traits, such as development period and
fecundity, which ultimately determine population growth rates. Understanding insects' …

When first instar nymphs and adults of the grain aphid Sitobion avenae
(Fabricius)(Hemiptera: Aphidiae) were maintained in long‐term cultures (> 6 months) at 20° …

The ability of first instar nymphs and newly moulted pre-reproductive adults of the grain
aphid S. avenae to rapidly cold harden was investigated. When nymphs reared at 20° C …

In contrast to previous studies of rapid cold-hardening (RCH), which have investigated the
responses of insects maintained undersummer conditions'(20° to 25° C), this study focuses …

1. An anholocyclic clone of the aphid Rhopalosiphum padi was reared on leaves of barley
seedlings at 20⚬ C in a 16: 8 LD photoperiod. First instar nymphs and newly moulted, pre …

Immature stages of the pea aphid, Acyrthosiphon pisum (Harris), from viviparous,
parthenogenetic populations, were exposed to hot and cold temperatures outside the …

The effects of brief exposures to sub‐zero temperatures (cold‐pulses) on wing development
were investigated in an anholocyclic clone of the grain aphid Sitobion avenae. A cold‐pulse …

The development, survivorship, and reproduction of buckthorn aphid, Aphis nasturtii
Kaltenbach, were evaluated at 7 constant temperatures (10, 15, 20, 25, 27, 30, and 35° C) …

Abstract Metopolophium dirhodum (Walker)(Hemiptera: Aphididae) is one of the three most
important cereal aphid species in Germany and central European countries. High …
