ALEALPA 
ALPALEA WEEVIL ( Hyp ora postica Gyll.) 
California. A. E. Michelhacher (Ja.nuary 3 ): One of the warmest falls 
experienced in lowland central California. In the northwostorn part 
of the San Joaquin Valley, the alfalfa has continued to make some 
growth, some heing 4 to 10 inches high on Lecomher I 9 , 1939* Alfalfa 
weevil found very active under those conditions, both larvae and 
adults heing rather abundant. In the more heavily infested fields, 
as many as SI adults and 240 larvae were collected per 100 sweeps of 
an insect net. Many of the larvae were small. In the less heavily 
infested part of the valley the population was small, and not more 
than 1 or 2 larvae or adults collected per 100 sw'eeps. In the heavily 
infested area 1 percent of alfalfa stems examined contained eggs. 
Altogether 7 hatches of eggs were found, all at about the end of the 
incubation period. (Pehruary 24) : On January IS in the region adjacent 
to the San Prancisco Lay, from 0 to 10 larvae were collected per 100 
sweeps. No adults collected. In the last survey in the San Joaquin 
Valley, conducted on Pehruary 12, the number of larvae per 100 sweeps 
ranged from 0 to 69 O, and adults from 0 to 22. Over a rather limited 
area near Tracy the weevil was rather abundant. Alfalfa ranged from 
less than one-fourth to one-third grown. Adult Lathynlgctes 
curculionis Thoms, were collected in fairly large numbers. Apparently 
the.y had only recently emerged from the long- cycle cocoons, as the 
number of parasitized larvae wa.s rather small, only about 5 percent, 
as determined by rearing out the parasites from last-instar larvae 
collected in the field. 
ALEALPA GATERPILLAE, ( Colias eui'*ytheme Bdv.) 
California. A. E. Michelhacher (January 3); In nearly all the alfalfa 
fields examined in the San Joaquin Valley on December I 9 , 1939, 
larvae were collected, the number ranging between 2 and I 5 » some of 
which were parasitized. (Pehruary 24) : The number of larvae collected 
per 100 sweeps in different fields in the San Joaquin Valley on 
Pehruary 12 ranged from 0 to Most of them were small and several 
found to be parasitized by Apantolos flaviconchae Riley. Number of 
larvae collected in the region adjacent to the Sa.n Prancisco Bay on 
January 18 ranged from 1 to several, most of which were small and a 
number parasitized by A. flaviconchae.
