Fire ants feed on poisoned vegetable weevils.--M. M. High, Gulfport, 
Miss., reports that "Early in the season fire ants (Solenopsis geminata 

am nae es ee 
the field that had been treated with arsenicals, but have not been found 
attacking active weevils." 
Mole crickets survive fast of 63 days.—~Reporting on the food habits 
of mole crickets, W. A. Thomas, Chadbourn, N. C., says, "Mole crickets 
(Gryllotalpa sp.) caged on moist sand without food have continued active 
for as long as 63 days. There is no noticeable growth during this period, 
but a gradual shrinking of the body, especially in the abdominal region." 

Feeding honey to adults of a wireworm increases egg production.—— 
C. E. Woodworth, Walla Walla, Wash., who previously noted that the feed— 
ing of pollen to females of Pheletes canus Lec. increased egg produc-— 
tion, now reports that "In a more critical series of experiments run re- 
cently in which washed pollen and pollen-—free honey were used instead of 
the pollen taken directly from the honey comb, it was found that the honey 
was the important factor that increased the egg production, although a 
mixture of pollen and honey was a little better than honey alone. Mold 
growing on pollen had a definite detrimental effect of about 25 per cent 
on the survival of egg-laying females in the breeding cages. Washed pol- 
len was found to be little, if any, better than no food at all, but honey 
was considerably better, whether alone or mixed with washed pollen." 
Wireworms become "hysterical."--"Some very interesting observations 
have been made regarding the reactions of the larvae (of Pheletes califor-— 
nicus Mann.) under the influence of minute concentrations of various fu-— 
migants," reports R. S. Lehman, Walla Walla. "The action of the larvae 
under the influence of chloropicrin is especially interesting. The gas 
seems to affect their nervous systems, as they are able to twist and 
roll but are unable to walk; although their legs do not appear to be par- 
alyzed, they seem to have no control over them. One and one~half months 
after exposure to chloropicrin some of the larvae are still alive but not 
normal. They do not feed and are unable to walk. They twist and roll 
and appear 'hysterical,' if one may describe it as such." 
Influence of temperature on Survival of submerged wireworm larvae,—- 
In a summary of results obtained in 1932 "on larval Submergence at con- 
Stant temperatures for certain definite periods of time," E. W. Jones, 
Walla Walla, reports that "Twenty larvae (of P. canus); placed individ- 
ually in vials of tap water, were held at each constant temperature. The 
water was changed at weekly intervals. The experiments started on Novem— 
ber 12, 1931, and were stopped on November 22, 1932." At a temperature 
of 86° F. the submerged larvae lived 2 months; at 81.5° F., 32 months; 
at 68° F., 4% months; and at 54.5° and 50.0° F., practically no mortal+ 
ity occurred. It was also found that "Larvae of an approximate age of
