Part of the work included in this paper was carried out with a research grant at Leicester University and was presented as an M.Sc. thesis at Sheffield, 1955.

Extract

A survey of the parasites of aphids that occur on lettuce was made in two localities, in the Midlands and northern England, respectively, and a list of these parasites compiled.

A study was made of the Braconid parasite, Monoctonus paludum Marshall, in relation to its host, Nasonovia ribis-nigri (Mosley), on lettuce. Techniques for observing the parasite's behaviour towards various species of aphids are described and methods of conducting experiments on breeding success in species other than N. ribis-nigri are given.

Footnotes

*

Starý (1959) in a revision of the genus Monoctonus Haliday identifies M. paludum Marshall with M. crepidis (Hal.) which has been recorded from other aphid hosts on plants related to lettuce.

The term “non-lettuce aphids” in the text of the present paper refers to species of aphids which have been taken from plants unrelated to lettuce.
