California T„ D. Urbahns (February IS): Quite annuniber of complaints re- 
garding kernel-spot of pecan accompanied by nuts s'lo"n.ng this 
trouble have been received from all sections of the State during 
the past two weeks. The southern green plant bug or stink bug 
is usually blamed for this injury. The nuts '"ere punctured by

of necan ^as more widespread and more serious during 1926 than 
during any previous; year.' Of course, other insects may have 
caused part of this' injury. 7e have no definite data to indicate 
what- species of insects were concerned in causing this injury,

blame.

CITRUS AND subtropical fruits 
ga^LYBTJgS ( Pseudococcus spp. ) 
T. D. Ur banns (February 17): Mealybugs., of several soecies, 
including Fseudococcus citri Risso, Pseudococcu s maritimus 
Ehrh. , Pseudococcus gahani G-reen, and others continue as serious 
pests of citrus trees, while they are also causing considerable 
loss to grape and pear growers. In addition to this, they are 
considered of economic importance to ornamental nursery stock. 
SCALE INSECTS (Coccidae) 
T. D. Urbahns (February 17): Citrus scale insects, including the 
gray scale, Ooccus citricola Champ. , the black scale, Saissetia 
oleae Item., the red scale, Chr:/somphalus auraiitii Mask., and 
others continue to be very destructive throughout many of the 
orange and lemon districts. In some districts control is reasonably 
successful by the use of oil sprays, while i- n others double 
treatment ^oy both spraying and fumigation is necessary. 
SPIRAFA APHIS (Aphis soiraecola Patch) 
J. R. T a tson (Febr-oary 15): Citrus aphids, which were getting 
very numerous in December, received a severe setback in January 
through the killing of all tender foliage by the severe freezes 
of that month. Most of them starved to death through lack of 
food. However, they -ire rapidly increasing bi\^. give promise of 
doing damage to the tangerine crop, and perhaps to the blossoms 
of orange.
