Ventura, Calif., says: "The effects of the temperature are best shown by 
the number of generations of the pod borer in the (last) two seasons. 
In 1931 there were from three to five generations, whereas in 1932 there 
were only two, with a possible partial third. The hibernation period in 
1932 began on July 20. * * * no larvae maturing before July 20 hibernated 
but 12.34 percent of the larvae maturing between July 20 and July 31 hi- 
bernated. The percentage of larvae that hibernated from those that ma- 
tured in successive 10-day periods steadily increased" from 12.34 per- 
cent for the period July 20 to July 31 to 100 percent for the period 
september 11 to November 7. 
Feeding of desert lizards vs. parasitization of beet leafhopper.—- 
George F. Knowlton, Logan, Utah, reports that "To determine frequency 
of internal parasitization in the leafhoppers ingested by the desert 
lizards, as compared with parasitization in the material taken in sweep-— 
ings, 1,870 individuals taken from lizard stomachs, mostly during October, 
were dissected. Two Pipunculus parasites were found in the 168 adult 
Butettix tenellus Bak. dissected, and only 1 Pipunculus was taken from 
1,702 nymphal tenellus. This did not indicate that the lizards were 
taking more than the average proportion of parasitized beet leafhop— 
pers."' Mr, Knowleton reports further on lizard predators of beet leaf- 
hoppers: "In the season of 1932, 958 brown-shouldered Utas, Uta stans— 
buriana stansburiana (B. and G.) were taken among common host plants 
Of E. tenellus; of these, 521 contained a total of 1,311 adults and 
5,824 nymphal tenellus. A total of 133 sagebrush swifts, Sceloporus 
graciosus graciosus (B. and G.) were taken among host plants (or other 
E. tenellus. Lizards of a few other species had fed upon beet leafhop— 
pers, as shown by the stomach contents of at least one specimen. A 
large number of lizards were taken among host plants, such as sage and 
rabbit brush; occasionally a specimen of the smaller lizards had taken 
@ tenellus." 
Clean-up of nightshade aids in control of pepper weevil.--"The his- 
tory of the occurrence of nightshade (Solanum spp.) in the pepper-—grow-— 
ing area of Orange County is interesting," states Roy E. Campbell, Al- 
hambra, Calif., "When the pepper-weevil investigation was started and 
for a few years thereafter, nightshade was very common all over the area 
* * * After the heavy losses from pepper—weevil damage in 1931 the grow-. 
ers became nightshade conscious. This year it is difficult to find per- 
ennial nightshade in some areas. The annual varieties are killed read-— 
ily by light frosts. Fence rows, ditch banks, and other areas have been 
kept fairly clean of all weeds. * * * Nightshade is a host of the to- 
mato pin worm and a number of other truck crop insects, and we feel that 
the progress made so far in its eradication along with other weeds has 
very decidedly lessened insect damage to truck crops in that area. A 
group of Japanese growers form crews who cover their particular area 
each winter to see that every nightshade plant is destroyed. We do not
