As the larvae live for several years, infestation can only be prevented 

 by planting vines at a distance from these palms, or in cases where 

 this is impossible careful and systematic collection of the larvae 

 should be made. 



The distribution of this beetle is not well known, but in the localitv 

 in question it is found in very light sandy soil and only in the vicinity 

 of palms.

The pests of tobacco plants include wireworms, which are success- 

 fully kept iii check by the use of baits consisting of potato scraps ; 

 mole-crickets [Gryllotalpa sp.], which may be destroyed by pouring 

 oil suspended in water into their galleries ; and Noctuid caterpillar.^, 

 the ravages of which can only be prevented by hardening the ground, 

 various methods of which are suggested.

Pgrausta {Botgs) nubilaUs has been very destructive during the past 

 two years in the environs of Toulouse. The excessively dry summers 

 were probably responsible for the increase of this moth in maize fields. 

 Two generations have been observed in the locahty under review. 

 The moths of the first generation appear in June. The young cater- 

 pillars on hatching bore into the stalk. The second generation appears 

 in August. Hibernation takes place in the larval stage. A Tachinid 

 parasite infests both generations of the caterpillars and in 1918 

 destroyed more than 20 per cent, in some districts.

Recent observations on the vine Pyralid [Sparganothiti pilleriana] 

 confirm those made previously [R.A.E., A, vi, 140] and show that 

 the hot water treatment is most efficacious provided it is conscien- 

 tiously and systematically carried out. On all the branches examined 

 the only living insects were found where the jet had not penetrated 

 sufficiently, i.e., the cracks at the junction of the branches with the 

 main stem or on the under surface of their branches which the water 

 had not reached directly and had therefore lost its heat.

An account is given of experiments that were interrupted by the 

 War and which have led to no very definite conclusions. In Lower 

 Charente all kinds of vegetation are liable to attack by termites
