dc.description.abstract I. — The period 1924-1927 has been marked out in the East of France by heavy attacks of Bupalus piniarius L. (Lepidopt. Geometridae) in the pine-forests of Haguenau and of Dasychira pudibunda L. (Lepidopt. Lymantriidae) in the broad-leaved forests. B. piniarius was particularly prejudicial.— Followed by Myelophilus piniperda (Coleopt. Ipidae), it determined, at Haguenau only, untimely fellings of 35.000 cubic-meters. II. — At the end of September 1927, a bacterium which contaminated the larvae of D. pudibunda, has been isolated. —This germ presented some resemblance with a bacillum, parasite on Schistocerca, isolated and described by D'HÉRELLE, and on which trials were made to destroy these Insects. The bacillum parasite on D. pudibunda larvae, interesting at a theorical point of view, seemed to be difficult to use practically. III. — In the forest of Haguenau, another way of destruction was adopted : an aircraft, loaded with pulverulent calcium arsenate, poured the poison on the crowns of the injured crops. — Inspite of the gropings impossible to avoid at the start of such a new method, this process, already employed abroad several times, seems apt for doing a good service. en
