severe fumigation can be considered as slightly detrimental to the 
forcing quality.) However, Golden Spur fumigated for 16 hours in a 
dosage of 5 ounces NaCN per 100 cubic foot shows almost no difference 
as compared with the check in time of blooming, quality of bloom, or 
quantity." 
In his study of the life history of the bulb mite (Rhizoglyphus 
hyacinthi Bdv.), R. H. Nelson, .Sumner, .Wash., finds, "At (O° )sssiee 
humidity 90, 100 per cent of the eggs hatch in 4 to 5 days, the larval 
stage lasts from 3 to 4 days, and the quiescent period between the larva 
and the protonymph is 1 day. Adults in incubator (70° F.) mate within 
1 day after emergence; egg laying begins 1 to 2 days after emergence; and 
1 mated female laid 99 eggs in ll days. One pair kept at room temper— 
ature were still living in apparently good condition after 49 days, 
and eggs are still deposited at intervals, 1 or 2 at a time. Females 
apparently will not oviposit unless fertilized." 
Ralph Scopp, Sumner, engaged in a study of the biology of Liothrips 
vaneeckei Priessner, reports that "Eggs kept in the incubator (at 70° 
F,.) are hatching in 6 to 15 days. The peak appears to be about 10 to ll 
days, although there are still eggs in this series which have not hatched. 
Eggs laid in November and December and kept at room temperature are not 
yet hatching (except 1 which hatched after 37 days). These eggs have 
been under observation from 72 to 81 days. These egg results indicate 
that fall-deposited eggs have hibernating qualities. One individual, 
emerged from pupa on December 20, began laying eggs January 3, and by 
the end of January hed laid 30 eggs. Two of these have hatched. This 
indicates parthenogenesis. Pupal periods of three individuals were 14, 
Voeweandu Le 1days.! 
K. B. McKinney, Tempe, -Ariz., reports "the finding of adult (to- 
bacco stalk) borers (Trichobaris mucorea Lec.) feeding on young Datura 
sprouts in protected places on January 20, although this winter has 
been the coldest on record since the winter of 1912 and 1913. An 6x— 
amination of a large quantity of Physalis stems that were killed by 
the first frost early in the fall shows that about two-thirds of the 
adults have left the cells but are still inside the stelks. OnwJante 
ary 21 one live pupa was found in dry Physalis stems and on January 
29 a live larva was taken from these dry stems." 
Reporting on control of the pepper weevil (Anthonomus eugenii 
Cano), J. C. Elmore, Alhambra, Calif., says: "The pepper growers have 
shown a keen willingness in following our clean-up recommendations this 
winter. The larger per cent of the pepper fields were plowed as early as 
the rains would permit and in one locality the Japanese growers organized 
crews to go along roadsides and other waste places to destroy the night-— 
shade. The Agricultural Commissioners are forcing land owners to clean 
up the few remaining pepper fields that are still standing. On January 
19 it was reported that clean-up control could not be continued because 
it was necessary to find live pepper weevils on the old pepper plants,
