Report of the State Entomologist of Connecticut for the year .. . 1938 7 85 4 42 4 41 4 51 3 22 6 13 28 254 FALL, 1938 29 370 4 81 3 20 8 111 24 173 2 19 4 28 4 10 1 10 3 5 3 72 4 45 1 3 1 5 2 6 Totals 93 958 Japanese Beetle Work in Connecticut, 1938 57 The information obtained by the grub diggings was used as a basisfor releasing the grub parasites, Tiphia vernalis, Roh., and Tiphia popill-iavora, Roh., by the United States Department of Agriculture, Rureau ofEntomology and Plant Quarantine. Fifteen colonies of T. vernalis werereleased in the spring of 1938, and 18 colonies of T. popilliavora in the earlyfall of 1938. The number of colonies of parasites released in Connecticutfrom 1936 to 1938, inclusive, now totals 23 of T. vernalis, 24of T. popill-iavora, and three of Centeter cinerea, Aldrich. Further information on these parasites will be found under Report on Parasite Work, 1938 in this bulletin. JUNE a u L^br ^^. LJ G- U ^ X Figure 2. Chart showing adult Japanese beetle populations in Hartford, trap record. Adult Japanese Beetle Populations The regular trap collections to obtain information on the relativeabundance of beetles were made again during the past summer collections were made in Hartford and Putnam. Through thecooperation of the Hartford Park Department, the beetles captured in thetrap at Hartford were removed daily. They were collected once a weekand recorded by Mr. George Smith of the Experiment Station. Mr. McEvoy, of the Connecticut Gypsy Moth Control Office, Danielson,made daily collections of the beetles captured in the trap at Putnam. Healso collected by hand daily all beetles seen in the immediate vicinity ofthe trap. The record of the systematic hand collections in Putnam wasincorporated on the chart together with the trap records, as the numbersof the beetles captured daily in the trap were very small.
