Scirtothrips citri, Moul. (citrus thrips) has been unusually abundant 

 in Tulare County orange groves. Orchards that were sprayed with 

 a high dosage of hme-sulphur and Triumph miscible oil showed a 

 marked freedom from this pest in comparison with fumigated or 

 untreated orchards, owing to the heavy coating of lime-sulphur 

 keeping some of the eggs from hatehing, or preventing the thrips 

 from attacking the first spring growth. This spray, if applied just 

 after the blossoms had fallen, would have prevented all damage by 

 the pest.
