Lamiman (J. F.). The Italian Pear Scale on Nursery Stock. — //. 



Econ. Ent., Geneva, N. Y., xv, no. 3, June 1922, p. 250. 



Epidiaspis piricola, Del Guer., has been recently found infesting 

 Myrobalan plum nursery stock in California. The scales were embedded 

 in the trunks of the seedlings just above the surface of the ground. 

 They were so well hidden as to have passed inspection in two counties. 

 The danger of the dissemination of the pest by this means is evident.

In Cnlifornia. Pseiidococcns longiseiosus, Ferris [R.A.E., A, viii, 187] 

 has been found associated with ants on roots of poison oak {Rhus 

 diversiloba), and Phenacoccns colemani, Ehrh., described from Rubus 

 sp., has now been found associated with ants under rocks and feeding 

 on grass roots.

 XV, no. 3, June 1922, p. 260. 



Carpophilus kemipferus, L., breeds freely in stored dried fruits in 

 th« warmer valleys of the interior of California, but is not so serious 

 a pest as Plodia inter punctella, Hb. Figs are apparently the preferred 

 food and are infested both in the store-houses and in the orchards, 

 particularly when there is any indication of souring ; and the beetle 

 also breeds freely in smutty figs, decaying melons or apples, and any 

 other rotting organic matter. 



AiNSLiE (G. G.). U.S. Bur. Ent. The Corn Lea!-tier, Lerema accius, 

 S. & A. — Florida Ent., Gainesville, vi, no. 1, June 1922, pp. 1-4 

 & 10-14. 



The Hesperid, Lerema accius, S. & A. (corn leaf-tyer), although not 

 known to cause appreciable damage, is a potential pest of maize, which 

 is its preferred food-plant, others being American wistaria {Bradleya 

 frutescens), sorghum, upland rice and several native grasses. The 

 life-cycle, from egg to adult, required 65 days in the spring of 1913, 

 so that there may be several generations annually ; it is probably a 

 continuous breeder in its permanent range in the south-eastern States, 

 and travels northward every summer and is killed in numbers each 

 winter. The eggs are laid singly and widely scattered on the leaves, 

 and the incubation period appears to be about nine days. The young 

 larva rolls the edge of a leaf over until it forms a tube tied down with 

 silken threads. It remains within the tube in the daytime, feeding 

 on the leaf, and at night emerges and attacks the same or other 

 leaves. The larval period occupies about 42 days, after which 

 pupation, lasting about 14 days, takes place on the leaf, under silken 

 threads. 



The Chalcid, Xenufens ruskini, Gir., has been observed emerging 

 from the egg of L. accius; a Braconid, Microdus sp., has been reared 

 from the larva ; and another Chalcid, Eitplectrus insiietus, Gah., also 

 emerged from the larva. There are probably other parasites not yet 

 observed, and the normal scarcity of larvae may be due to their 

 activities.
