AbstractAdult behaviour and oviposition patterns of Cacoecimorpha pronubana (Hb.), Phlogophora meticulosa (L.), Autographa gamma (L.), Mamestra brassicae (L.) and Lacanobia oleracea (L.) were studied by introducing laboratory reared pupae into glasshouses. Adults emerging from these pupae were located by direct visual searching of chrysanthemum plants and of the greenhouse structures for up to three weeks after emergence.In small houses (2·9×3·3×2·5 m), 49 adults of C. pronubana emerged. At least 15 stayed inside the house and laid 1 750 eggs. With P. meticulosa, A. gamma and L. oleracea, 262 adults emerged and escaped from the houses without laying eggs inside.In a large glasshouse (9·8×13·1×5·1 m) with automatic ventilators, 840 adults of P. meticulosa, A. gamma and M. brassicae emerged and many were prevented from escaping when the ventilators were closed during the moths' flight period. Moths were inactive in daytime and most were found on the highest parts of the aluminium framework, mainly on the sides which received most external light overnight. None were found on the glass. Only 27·3% of the P. meticulosa were found on the plants. Moth distributions probably result from moths flying until they reach a barrier, which they then tend to follow, with directional responses to gravity, light, settling site, food plant and oviposition site superimposed in varying degrees on this basic pattern. About 30 470 eggs were laid, more in outer than in inner beds and more in the outer than in the inner rows of a bed. P. meticulosa and A. gamma laid eggs only on plants. M. brassicae laid about 1 854 eggs on the undersides of leaves and 2 972 on glass and framework, mainly in the direction of external light.All five species can cause serious damage to crops. Initial infestations can be controlled by sprays of chemical insecticides or Bacillus thurin-giensis. Usually a few larvae survive a single spray and, in the absence of further control measures, they may produce a troublesome second generation, although in certain circumstances further control measures may not be required. If biological control of other tomato pests becomes widespread, steps should be taken to prevent L. oleracea again becoming an important pest.

Increased doses of tepa applied by injection to female Diparopsis castanea Hmps. caused a progressive increase in sterility accompanied by a decrease in the number of eggs oviposited from the time of application. After an interval of three days it was shown by histological examination that injected doses of 10 μg of tepa induced degeneration of the developing oocytes and a shrinkage or resorption of some of the mature eggs. After Diparopsis male moths were treated with graduated injected doses of apholate, metepa and tepa and then mated with untreated females, considerable embryonic development without subsequent egg hatch occurred at the lower dosage levels. When tepa-treated Autographa gamma (L.) males at a dose of 10 μg were similarly mated with untreated females histological examination showed that the development of many of the eggs had been arrested at a very early stage; in some instances a greater development, although of an abnormal kind, had taken place.

AbstractThe continuous operation of insect-monitoring radars in the UK has permitted, for the first time, the characterization of various phenomena associated with high-altitude migration of large insects over this part of northern Europe. Previous studies have taken a case-study approach, concentrating on a small number of nights of particular interest. Here, combining data from two radars, and from an extensive suction- and light-trapping network, we have undertaken a more systematic, longer-term study of diel flight periodicity and vertical distribution of macro-insects in the atmosphere. Firstly, we identify general features of insect abundance and stratification, occurring during the 24-hour cycle, which emerge from four years' aggregated radar data for the summer months in southern Britain. These features include mass emigrations at dusk and, to a lesser extent, at dawn and daytime concentrations associated with thermal convection. We then focus our attention on the well-defined layers of large nocturnal migrants that form in the early evening, usually at heights of 200–500 m above ground. We present evidence from both radar and trap data that these nocturnal layers are composed mainly of noctuid moths, with species such as Noctua pronuba, Autographa gamma, Agrotis exclamationis, A. segetum, Xestia c-nigrum and Phlogophora meticulosa predominating.

Natural Pheromone

Z-7-Dodecenyl acetate and Z-7-dodecenyl alcohol have been identified as sex pheromone components o f female Autographa gamma. This is the first time that Z-7-dodecenyl alcohol has been found in the natural pheromone of Plusiinae. When incorporated in pherom one traps of some Plusiinae species the alcohol is both synergist and inhibitor, thus being an important factor in sex isolation among sympatric Plusiinae species in Israel
