Maine Insects Affecting the Blueberry . To (l) strengthen 

 insect pest control program and attempt to find formula- 

 tions more stable under adverse weather conditions; (2) 

 find adequate control measures for late blueberry maggot 

 in fruit destined for frozen or fresh fruit market; (3) 

 amplify data obtained on pollination, and learn if inten- 

 sive pollination woiild result in a stand of undersized 

 berries; and, (k) continue biological studies on destruc- 

 tive pests of blueberries.

Minn. Fmit Insect Pests . To (l) determine role of insects 

 and mites in increasing number of crop failin-es that are 

 being reported by strawberry growers; (2) select insecti- 

 cides and an adequate spray schedule for control of insect 

 pests of such small fruits as strawberries, raspberries 

 and currants; (3) test new mater isuLs that may fit into the 

 tree fruit spray schedules; and, (k) determine annually the 

 nature and amount of damage that has occiirred in Minnesota 

 fruit plantings.

Calif. The Nature of and Predisposing Factors for "Wetness" of 

 Table Grapes and the Relationship of this Condition to Market 

 Quality ^ To (1) specify what wetness is; (2) determine sig- 

 nificance of moistxire of condensation in relation to wetness; 

 (3) determine role of condensed moist^ire in predisposing the 

 fruit to decay; {k) determine significance of berry juice in 

 relation to wetness; (5) evaluate relationship of rough hand- 

 ling to berry injury in terms of amoiint of wetness; (6) deter- 

 mine relationship between wetness from injury and decay inci- 

 dence; (7) determine if use of excessive amounts of SOp for 

 fumigation predisposes fruit to wetness; (8) determine signif- 

 icance of microscopic injuries such as insect piinctures in 

 relation to wetness; (9) learn changes in permeability of 

 the skin to juice diiring stages of senescence of fruit during 

 storage; (lO) learn if wetness is correlated with maturity 

 of fruit when harvested; and, (11) learn influence of differ- 

 ent degrees cmd types of wetness upon market quality of fruit 

 as indicated by wholesale and retail prices.
