Concerning studies of chestnut weeviis by himself and assistants 
at the Takoma Park laboratory, Mr. Siegler states: "It is of interest 
to note the great preponderance of the smaller chestnut weevil (Curcu- 
iio auriger Casey) over that of the larger (C. proboscideus Fab.). Up 
to the present writing we have reared 61,323, out of which 99.4 per 
cent comprised the smaller species. Since the seasonal cycles of these 
weevils are somewhat unlike and require that control measures be taken 
at different times, it is obvious from the above disclosure of relative 
abundance that special emphasis should be given toward the control of 
the smaller species." 
H. W. Allen, in charge of investigations of parasites of the Ori- 
ental fruit moth (Laspeyresia molesta Busck) at Moorestown, N. J., says: 
"As a result of the recovery studies of this past season, a much clearer 
idea of the status of various Oriental fruit moth parasites has been ob- 
tained. There seems to be a fairly clear line of demarcation between 
those which attack the egg, the twig-—infesting larvae, or the cocoons, 
although except for Trichogramma, and possibly Apanteles, all emerge from 
‘the cocoon stage. The following species are preeminently cocoon para- 
Sites: (1) Aenoplex betulaecola Ashm., (2) Calliephialtes grapholithae 
Cress., (3) Centeterus ineptifrons Gahan, (4) Dibrachys boucheanus Ratiz., 
(5) Ephialtes aequalis Prov., (6) Epiurus indagator Cress., (7) Eupelmus 
amicus Gir., (8) Eurytoma sp., (9) Hemiteles tenellus (Say), (10) Ito- 
plectis conquisitor (Say), (11) Microbracon mellitor (Say), and (12) Per-— 
ilampus sp. Those emerging from the prepupa are numbers 1, 2, 4, and 5; 
meouevwne: pupa, 3, 5; 10, and 12; from either, 7, 8, 9. Numbers 1, 2353; 
5, 6, 10, 11, 12, and 13 have been recovered only as primary parasites 
of the oriental fruit moth, while 4, 7, 8, and 9, have been recovered 
both as primaries and secondaries. A final check of native parasites 
reared this year is: Twig-larval parasites, 15 known, 2 unknown, total 17; 
cocoon parasites, 12 known, 3 unknown, total 15; total parasite species 52." 
Mr. Allen notes that Macrocentrus ancylivora Roh. "was this year 
recovered from all but 3 of the 18 States in which recovery collections 
were made, and that these recoveries were from 56 counties widely scat— 
tered over this area. Only one species, Glypta rufiscutellaris Cress., 
was recovered from a larger number of counties (435). Since four years 
ago M. ancylivora was not known as a parasite of the peach moth out-— 
side a limited eastern distribution, this evidence of widespread dis- 
tribution following three seasons' colonization is quite pleasing." 
"The two most effective baits (for the oriental fruit moth) during 
the past season," according to L. F, Steiner, Cornelia, Ga., "were 10 per 
cent solutions of No. 3 remelt sugar with 1/4 cubic centimeter emulsified 
ethyl cinnamate per quart added, and medium soft sugar with terpinyl ace- 
tate added at the rate of 1 or even 1/4 cubic centimeter per trap. The 
latter appeared 75 per cent more attractive than the check which was a 
10 per cent medium soft sugar solution plus 1/4 cubic centimeter emulsi- 
fied ethyl cinnamate per trap. This check bait was the most attractive
