Bulletin No. 129 - Codling Moth Studies In 1911: The Driving Spray Under Excessively Wormy Conditions, E. D. Ball, W. M. Ball Nov 1913

Bulletin No. 129 - Codling Moth Studies In 1911: The Driving Spray Under Excessively Wormy Conditions, E. D. Ball, W. M. Ball

UAES Bulletins

Spraying experiments against the codling moth were carried on upon the Smart orchard until the number of worms per tree was reduced to such an extent that no accurate comparisons could be made between different treatments. As a result of the work on this and other orchards, practically every commercial orchard in the valley was by this time well sprayed and the worms reduced to a point where one driving spray per season would keep them under control.

In the meantime a number of questions arose which required very wormy conditions to adequately investigate. Search was therefore made for orchards …

Some of the material, mostly Megachilinae, Sphecodes and male Halictus, has not been identified, and is not included. A few of the determinations were made by Mr. H . L.

Descriptions Of New Hymenoptera, No. 7, J. C. Crawford May 1913

Descriptions Of New Hymenoptera, No. 7, J. C. Crawford

Co

Most of the species described in this paper are of economic importance, and for reference in economic literature their early description is desirable. The series from the species of Agromyza is noteworthy in view of the number of species previously described as parasites of the species of that genus. In this paper, in all cases where both sexes of a species are described, that last described is the allotype.

In this paper where both sexes of a species are described, that last described is the allotype. Comparative measurements where given in figures were made with the Zeiss binocular microscope equipped with No. 2 eyepieces and the a3 objective and an eyepiece micrometer.


Notes On Some Species Of The Genus Prosopis, J. C. Crawford May 1913

Notes On Some Species Of The Genus Prosopis, J. C. Crawford

Co

This is a valid species, and not a form of P. cressoni as it is given by Metz. Externally the two are easily seperable. P. cressoni has the propodeum coarsely sculptured, while Mesilla has it, very finely wrinkled. The eighth ventral plates of the males are quite different, and are therefore figured. In cressoni the apical lobes are much shorter than the pedicel attaching them to the plate; in Mesilla they are longer than the pedicel.

In dieser Zeitschrift, p. 579, veroffentlicht H. Friese einen Artikel "Uber einige nomenklatorische Anderungen", in welchem er ausfubrt, infolge davon, dafs durch J. Perez die durftige Beschreibung von E. longicornis Linne erganzt und auf eine bestimmte Art (namlich E. longicomis Perez, Friese) gedeutet und festgelegt worden sei, babe nur noch die Auffassung , Bescbreibung und Type von Perez Beweiskraft und nicht die von Linne. Dabei beruft Friese sicb ohne Berechtigung auf die internationalen Regeln der zoologischen Nomenklatur, Berlin 1901, V. § 1, 2 und 3.
