A detailed study of courtship in Spodoptera littoralis showed that there were four significant behaviour patterns. The male flew to a calling female and hovered above her with his brushes fully extended. In response, the female lifted her wings, curv

The life-span and fecundity of females of Spodoptera littoralis (Boisd.) of strains that originated from Crete and Egypt were studied in relation to delays in mating. Virgin females and those that were not mated until eight days from emergence lived

The contact toxicity of ten pyrethroids to larvae of Spodoptera littoralis (Boisd.) was investigated by topical application, and symptoms observed for different combinations of dose and time. Several compounds were sufficiently active to suggest that

[1. The amount of time spent in marching, basking, pottering and feeding was measured in small groups of gregarious fourth-instar hoppers of two locust species Locusta migratoria migratorioides (R. & F.) and Schistocerca gregaria (Forsk.) under vario

1. WhenLocusta nymphs are reared crowded they generally show a number of characteristics that are typical of swarm populations in the field, i.e. they march well, have low F/C ratios and are generally black and orange in colour in the later instars.

After exposure of nymphs of some Pyrrhocorid bugs to contact with certain papers or wood chips, abnormal adults are produced. Some have crumpled wings (distorted adults) and a proportion of these do not berrd, others have wing buds resembling those o

1. 1. Using the hoppers of two locust species, Locusta migratoria migratorioides (R. & F.) and Schistocerca gregaria Forsk., an attempt was made to study the importance of a patchy physical environment in bringing hoppers together long enough to beco

1. Restriction of social contact in hoppers of Locusta migratoria migratorioides (R. & F.) leads to reduced marching, so that animals reared in isolation march very little, even when placed in a crowd. Various types of restriction have been studied i

The amount of marching by 4th-instar hoppers of Locusta migratoria migratorioides (R. & F.) which have been reared in crowds, was studied in relation to the total number of individuals and to the size of the cage. Below 50 hoppers per cage, marching

Under field conditions bands of Locststa migratoria migratorioides (R. & F.) nymphs (hoppers) carry out a daytime wandering called marching, which is preceded by a period of basking in groups. The formation of these basking groups may depend entirely
