AbstractThe duration of flight by Nilaparvata lugens (Stål) of tropical origin from field and laboratory populations was studied. Field insects (from the third generation on rice) flew longer and more readily than laboratorybred insects. The longest recorded flight, of 10·75 h, was by a female from the field. Laboratory-reared insects performed poorly even after only one generation in the laboratory. Flights that were started in the morning lasted longer than those started in the afternoon. Lift production varied between individuals and during a continuous flight. Individuals flying for over 150 min tended to produce more lift for a longer proportion of the flight than those flying for less than 10 min. The pattern of lift production appeared to be similar in successive flights, except in those following very long flights when the insect appeared to be exhausted. There was no tendency for the first flight to be the longest. Up to 28% loss of body weight was recorded (in a flight lasting 512 min) during flight. The results indicate that individuals from tropical field populations of N. lugens have the capacity for long range migration.

Since the 1990s, a new type of Holocaust story has been emerging in Israeli children's literature. This new narrative is directed towards very young children, from preschool to the first years of elementary school, and its official goal is to instil in them an authentic ‘first Holocaust memory’. This essay presents the literary characteristics of this new Holocaust narrative for children and its master narrative. It brings into light a new profile of both writers and readers. The writers were young children during the Holocaust, and first chose to tell their stories from the safe distance of three generations. The readers are their grand-children and their grand-children's peers, who are assigned an essential role as listeners. These generational roles – the roles of a First Generation of writers and of a Third Generation of readers – are intrinsically familial ones. As such, they mark a significant change in the profile of yet another important figure in the Israeli intergenerational Holocaust discourse, the agent of the Holocaust story for children. Due to the new literary initiatives, the task of providing young children with a ‘first Holocaust memory’ is transferred from the educational authority, where it used to reside, to the domestic sphere.
