Scientific Notes 
A Pecan Case-bearer. During the past winter considerable numbers of various 
varieties of pecans have been introduced into widely separated parts of California. 
With the advent of spring and the leafing out of the trees it has been found that those 
trees that were introduced from Monticello, Florida were quite heavily infested with 
a leaf case-bearer, which seems to be Acrobasis nebulella Riley. The County Horti¬ 
cultural Commissioners are taking steps to eradicate the pest before it becomes 
established, as some fear is felt that it might attack English walnuts, of which there 
are large plantings. Adults were noted to be emerging during the second week of 
June. Clifford T. Dodds 
An Infestation of Autographa biloba Steph. on Lettuce. Early in June an out¬ 
break of caterpillars causing extensive defoliation of lettuce in a cold frame was noted 
at A & M College, Mississippi. Both the caterpillars and cocoons closely resembled 
those of Autographa brassicae, but since this species though always abundant in this 
section on cabbage and closely related cruciferous crops, rarely if ever becomes a pest 
on lettuce, it was suspected that another species was involved. Specimens of larvae 
and cocoons were collected and reared, the adult being determined by Mr. F. H. 
Benjamin of Decatur, Illinois as Autographa biloba Steph. 
The damage by this species to the lettuce in the cold frame was complete, the 
defoliation approaching one hundred per cent. Lettuce in the garden outside the 
frame, less than one hundred feet distant from it, remained untouched. No other 
infestation has been seen in the locality, and although all the pupae in the insectary 
have emerged there has been up to the time of writing (July 5th) no recurrence of 
infestation on the location of the original infestation. 
Twenty specimens were taken to the insectary. Twelve of these emerged, and six 
succumbed to a malady having the characteristic appearance of a polyhedral disease. 
One of the six was examined and found to contain great numbers of the polyhedral 
bodies typical of this type of disease. No parasites were reared.
