EECE>'T PAPERS ON EUROPEAN GRAPE INSECTS. 



Our energetic and enterprising friend, M. V. Vermorel, the founder 

 and owner of the Viticultural Experiment Station at Yillefranche, 

 France, which we tisited last year, has just published the first two 

 numbers (in one volume) of a new quarterly journal * devoted to viti- 

 culture. The volume is almost entirely taken up by two excellent en- 

 tomological papers. The first is entitled '^ Contributions a Petude du 

 Gribouri,'' by E. Dnpont, and gives careful original observations on the 

 oviposition and larval injury of Adoxus vitis, a Chrysomelid beetle 

 which is very injurious to the grape in Europe, and which occurs also 

 in the boreal portion of !North America. A colored plate illustrates the 

 egg and the young larva, while two other plates illustrate contrivances 

 to observe the working of the larva on the roots of living plants. The 

 second paper is a very complete monograph of " La Cochyle " which is 

 a Tortricid moth [CochyUs ambiguella Hltbn.), and next to the Phylloxera 

 perhaps the most important grape insect in France. The chapter on 

 the various remedial measures is especially full and will be found of 

 great interest to our own economic entomologists, although the insect 

 itself fortunately does not occur in ^S^orth America. Three well exe- 

 cuted colored plates illustrate the various stages of the Cochylis and the 

 work of the larva on the blossoms and berries. 



CODLING MOTH LEGISLATION IN N^EW ZEALAND. 



During the past two or three years there has been a great deal of 

 talk in Xew Zealand with regard to instituting some legislation against 

 the Codling Moth and several acts have been proposed inj;he house of 

 representatives. So far as we know, however, no actual laws are yet 

 enforced. In the Keic Zealand Farmer for August 18, 1890, we notice 

 that Mr. Wight has published some very pertinent criticisms on the pro- 

 posed legislation. He shows that the marked differences between the 

 Phylloxera and the Codling Moth consists in that with the latter insect 

 the tree is not destroyed nor even injured, and that there are many 

 remedies by which the insect may be killed. \Yith the Phylloxera, there- 

 fore, severe measures are to be employed, while with the Codling Moth 

 too severe measures will lead to unnecessary loss and to no ultimate 

 good results. As a rule orchardists may be trusted to look after their 

 orchards, requiring only protection from their careless neighbors. Mr. 

 Wight seems to think that these latter should not be fined, but that 

 some working gardener should be induced to go into the business and 

 should be permitted to spray trees with Paris green at a fixed rate. The 

 owners of the trees would soon find that the value of the apples saved
