Codling- Moth, On the Nut Feedingr Habits of the. By S. W. 



Foster {U.S.A. Dept. Agr., Bur. Entom., Bull. 80, pt. 5 Sept. 1910; 

 2 plates). — The codling moth has hitherto been considered as a serious 

 enemy of apples and pears only, although frequently found in plums 

 and peaches. In 1887, 1895-6 reports were received of the larv^ 

 attacking walnuts, but there was insufficient evidence to prove the 

 statements. 



In 1909 a large walnut tree adjacent to a pear-packing shed near 

 Concord, Cal., was found to be infested by the larvae of the codling 

 moth. Search through Contra Costa County, Cal., showed the trouble 

 to be general but light, except where trees were near packing-sheds, 

 drying grounds, or a badly-infested pear orchard. 



So far all observations indicate that only the later broods of larvae 

 attack the walnuts. Assuming that the larval life in walnuts is the 

 same in length as in apples and pears, the earliest date of infestation 

 would be late 'August or early September. The * Bartlett ' pear crop 

 in the locality is picked prior to this time and before all the second- 

 brood m.oths have developed. It is therefore probable that these lafe- 

 appearing individuals seek the walnut as the only remaining plant suit- 

 iable for oviposition. Thorough search in May and June 1910 failed 

 to show the presence of any larvae on trees that were badly infested 

 last season. — V. G.J.

Corfu. By C. Sprenger (Oester. Gart. Zeit. vol. vi. pt. 2, 

 pp. 60-63). — As a result of the complete destruction of the foi^ests the 

 climate of Corfu is wet in winter and very dry in summer. The 

 Macchia is composed of Quercus coccifera, Erica verticillata, E. 

 irborea, Arbutus Unedo, Viburnum Tinus, Myrtus communis, Pistacia 

 Terebi^ithus, P. Lentiscus, Salvia triloba, Laurus nobilis, Cistus cre- 

 "ticus, C. villosus, C. albidus, C. monspeliensis, and the Cypress. Cal- 

 ceolarias, Fuchsias, and tree ferns do not thrive, but Araliaceae and 

 joalms from dry countries flourish. Primulas, Cinerarias, Schizanthus, 

 Myosotis, Campanulas, Leucojum and Tulips, amply repay the trouble 

 )f cultivation. The water supply is very hard so it is impossible to grow 

 izaleas, Ehododendrons or Camellias. — S. E. W.
