Malva traps attract wireworms for oviposition.—-"To determine wheth-— 
er females trapped under piles of Malva (mallow) oviposited, fertile 
females were placed underneath such piles in shallow trays filled with 
fine mesh soil," reports M. W. Stone, Alhambra, Calif. "In one of these 
traps 1,066 eggs of Pheletes californicus Mann. were recovered on April 
7. In another where 9 pairs had remained during the period March 20 to 
April 15, 618 eggs were recovered. A reduction in wireworm population 
appears possible by the use of Malva in localizing oviposition and later 
fumigating the area beneath the traps." 
FOREST INSECTS 
Pine tip moth from Southwest thrives in Nebraska.--L. G. Baum- 
hofer, Halsey, Nebr., reports on Rhyacionia neomexicana Dyar, which 
was introduced by accident from the Southwest into the pine plantations 
of Nebraska National Forest, is increasing annually, and threatens 
to become a serious pest. He states: "In the first field observations 
on April 9 several adults* * * were taken in flight, indicating that this 
single-generation species begins emergence as early as the two-generation 
R. frustrana bushnelli Busck (a better known and more widely distributed 
Species). Cool weather retarded emergence of R. neomexicana for a time 
but on April 23, following 2 days of warm rain, a fairly heavy emergence 
of this tip moth occurred. The cocoons of R. neomexicana, spun last 
July, have been found concentrated at the base of the infested pine trees 
in the bark crevices or attached to the bark at or just below the soil 
Surface, beneath the litter." 
Parasites recovered from pine moths.--P. B. Dowden, Melrose High-— 
lands. Mass., states that J. V. Schaffner, Jr.'s "collection in America 
of the European pine shoot moth (Rhyacionia buoliana Schiff.) material 
last summer produced the following parasites: Orgilus obscurator (Nees), 
Eurytoma tylodermatis Ashm., Hyssopus thymus (Gir,), Calliephialtes com- 
stocki (Cress.), Epiurus indagator (Cress.), Ephialtes conquisitor (Say), 
?Scambus pterolas Say, Microbracon sp., and Goniozus sp. Orgilus ob-— 
Scurator is a species indigenous to Europe, evidently introduced with the 
host. Practically all of the species have been reared from the Nantucket 
pine moth (Rhyacionia frustrana Comst.) also." Mr. Dowden submits the 
following regarding European parasites of the pine shoot moth: "In 1932 
a very high percentage of hymenopterous cocoons reared from R. buoliana 
in Austria produced the hyperparasite Perilampus tristis Mayr. Mr. Sellers 
was therefore requested to make a collection of overwintering larvae of 
R. buoliana and send them to Melrose Highlands last winter * * * 100 
larvae were dissected in April with the following results: 42 contained 
planidia (mobile first-stage larvae) of Perilampus, probably P. tristis; 
14 contained Cremastus interruptor Grav.; 6 contained a braconid, prob- 
ably 0. obscurator. None of the Cremastus interruptor or Orgilus ob- 
socurator larvae had planidia inside them, although two of the buoliana 
larvae parasitized by Cremastus and two parasitized by Orgilus also
