30 General J^Totices. 



the work, in the Gardener's Magazine. Prof. Audouin, howovpr, 

 will publish a volutne upon tlie subject, under tlie auspices of tlie 

 French jrovernment. It will be in quarto, with an atlas of twenty- 

 three colored plates, in five or six numbers (or livraisons,) at ten 

 francs each. After trivin^ a history of the insect, and an interestinj^ 

 account of the very singular tnanner in which the eiriis of the female 

 are fecundated, he gives the following mode of destroying the in- 

 sects. 



M. Audouin states that the mode of destroying the insect, which 

 he found most effective, is, to place among the vines, in the night 

 time, lamps enclosed in glass, and suspended over a saucer of oil, or 

 any greasy or viscous matter. The moth flies to the light, which it 

 is [)revented from touching by the glass, while, by repeatedly strik- 

 ing against it, in its endeavors to get at the li^ht, it dro[)s down, and 

 is drowned or fixed in the oil or greasy matter. One cultivator, in 

 the year 1837, put down in his vineyard, in one night, two hundred 

 of these lamps, at twenty-five feet apart every way. The lamps 

 hurupd for about two hours, during which time, an average of one 

 hundred and fifty moths were fixed in each saucer, making, in all, 

 thirty thousand insects. A fifth part of that nnmlier of moths con- 

 sisted of females, each of whom would have laid one hundred and 

 fifty eggs, which, in a few days, would have produced nine hundred 

 thousand caterpillars. Aui:ust 7th, one hundred and eighty lamps, 

 ])l;iced in the same vineyard, and for the same period, caught each 

 eishty moths, making, in all, fourteen thousand insects, three fourths 

 of which were females: but admitting only the half, or seven thou- 

 sand two himdred females, in multijjlyiiig that number by one hun- 

 dred and fifty, the number of e'j<xs that each female is supposed to 

 lay, the total number of caterpillars destroyed will be one million 

 and eighty thousand. Another mode which M. Audouin recommends 

 is, gathering the leaves or the points of the shoots, immediately after 

 the eggs have been deposited, or when they have been newly hatched. 

 As the eggs are always laid upon the upper surface of the leaf, they 

 are easily detected by women or children. By this process, twenty 

 persons, between the 7th and 11th of August, gathered one hundred 

 and eighty-six thousand nine hundred nests of eggs, and, as each 

 nest contains, at an average, about sixty eggs, the total number 

 destroyed was eleven million two hundred and fourteen thousand. 



Upon this, the conductor of the Gardener''s Magazine remarks, 

 that though the subject is, no doubt, of more interest to the Continent- 

 al than the British gardener, still, the latter might adojjt both the 

 lamp and gathering S3'stems amon<r his cabbages and gooseberries; 

 and we think that our amateurs may also learn something from the 

 experiment tried by M. Audouin. The gooseberry moth might 

 undoubtedly be easily entrapped in this manner, and where there are 

 only a dozen or two of plants, with very little trouble, as two lamps 

 at the most, would be all that would be required, and they need not 

 be lighted more than six or eight nights. Perhaps the curculio, 

 which is so troublesome to the plum, might be ciUL^ht in the same 

 manner. It is true it is not one of the moth tribe, but, as it 

 flies from branch to branch, attacking the fruit, it would, no 

 doubt, be attracted by the light, and, in its attempts to reach it, fall 

 into the saucer of oil: one lamp suspended in a tree, would be suf- 

 ficient. We should be glad to see the experiment tried, and we
