7 of this year in relation to the brood of 1932 and in the fall in relation 
_to the current brood, "indicate that the beetle in this region is showing 
a tendency to a partial 2-year life cycle, a condition known to occur in 
_the northern part of its range in Japan."

the original formula of lead-oleate-coated lead arsenate was published 
in 1926, there have been several modifications," reports W. E. Fleming, 
Moorestown. "As a result there was apparently no agreement between 
this original formula and the formulae presented by the different man- 
ufacturers. Conferences were held with P. A. van der Meulen, formerly 
of the Bureau, who developed this formula, and with representatives of 
the manufacturers. Standard specifications for lead—oleate-—coated lead 
arsenate have been drawn up which will permit the manufacture of a suit— 
able product." 
TRUCK CROP AND GARDEN INSECTS 
Emergence of Mexican bean beetle on Eastern Shore of Maryland.-—— 
According to L. W. Brannon, Norfolk, Va., "The results of emergence 
from the hibernation cage at Allen, “d., to date indicate that beetle 
Survival will be very close to that of last year. The emergence was 
eo.20 percent on May 24 this year and 26.02 percent on May 24, 1932." 
No home life for male earwigs.-—"Some rather interesting new facts 
in regard to earwig Oviposition have been obtained from 10 females dug 
up in the act of attending eggs in March end kept in the laboratory since 
Thav time,” reports S. E. Crumb, Puyallup, Wash. "As the eggs hatched 
the progeny of each female were. removed and are being reared singly to 
maturity. Of these 10 females, which are known to have deposited the 
usual number of eggs, 5 have now deposited a second lot of eggs——a 
thing we had never expected them to do * * * A female earwig with young 
Was dug up on May 10 and was entered in a salve jar with two males. * * * 
On May 27 the female was caring for a mass of eggs. On May 29 one of 
the males was observed in a mangled and dying condition and on June 1 
the remaining male was mangled and dead. The female is very solicitous 
of her eggs and, apparently looking upon the male as a menace to then, 
slaughters him with her scissorslike forceps if he is not able to escape. 
Apparently, to save their lives, the males leave the females about the 
time the eggs are deposited." 
Wireworm fails to pupate at constant temperatures.--C. E. Wood- 
worth, Walla Walla, Wash., reports "an unusually interesting series of 
results * * * in our attenpt to get completed life histories (of Limonius 
Ganus Lec.) under controlled conditions. It has been noted that at 
constant temperature (63.5° F.) pupstion was not taking place. Larvae 
of full size and considerable age were pupating only occasionally. 
Preliminary experiments indicated that variable temperature would prob- 
ably remedy this condition. Consequently certain larvae were subjected 
to higher temperatures (81.5° F.) and fair results were obtained. Quite
