Summary The titre of insulin-like-peptides (ILP) in the haemolymph, developing oocytes and developing eggs was examined by a radioimmunoassay for human anti-insulin. ILP in the haemolymph increased in a two-stage pattern during oogenesis, but fell at

The blood volumes of locusts were determined by the 14C-carboxyl inulin dilution technique. In each of the last two larval instars the blood volume was low at first, increased sharply at midstage, and remained high until after ecdysis, when it sudden

Selected blood proteins were studied during the fifth instar of Locusta by means of acrylamide 'disc electrophoresis' after injection of 3H-labeled blood proteins or 3H-leucine. Label was found to accumulate in the "common protein" fraction in the mi

Parasitism of pupae of G. mellonella (L.) by P. turionellae (L.) was found to prevent adult emergence. The effect was manifest within 24 hours of parasitization. Experiments are described which indicated that the source of the factor preventing eclos

Haemolymph from 6th instar larvae of Malacosoma americanum and 5th instar nymphs of Locusta migratoria was subjected to gel filtration on Sephadex G-200. Three protein fractions were produced in each case. Each fraction was analyzed for protein conte

Electrophoretic and gel filtration studies on the haemolymph of Chironomus riparius are described. The multiple nature of Chironomus haemoglobins was confirmed and the changes in haemoglobin pattern during development analyzed. Gel filtration studies
