CITRUS 



Quarterly Citrus Insect and Mite Outlook in Florida - July through September - 

 This Outlook is based on the assumption that weather beyond the period of the 

 current National Weather Service 30-day Outlook will be normal. Therefore, the 

 forecasts given below cannot be viewed with the same degree of confidence as 

 those in the "Insect and Disease Summary" usually released twice each month. 



CITRUS RUST MITE ( Phyllocoptru ta oleivora ) increase will continue through July, 

 hold at high level through August, and decrease in September. Heavy infestations 

 expected in 30 percent of groves. CITRUS RED MITE ( Panonychus citri ) and TEXAS 

 CITRUS MITE ( Eutetranychus banks! ) will recede from their abnormally high levels 

 during July and August and be at low levels by September. Only scattered groves 

 will have important infestations. GLOVER SCALE ( Lepidosaphes gloverii ) will 

 continue high through July, gradually decrease in August, and be at low to 

 moderate level by September. PURPLE SCALE (L. beckii ) , CHAFF SCALE ( Parlatoria 

 pergandii ) , and YELLOW SCALE ( Aonidiella citrina ) populations will remain below 

 normal and at low level. BLACK SCALE ( Saissetia oleae) expected to increase 

 during July, continue briefly in high range during August, and drop to moderate 

 level by September. Only scattered groves will have important infestations. 

 An ARMORED SCALE ( Unaspis citri) expected to spread and intensify during July and 

 September. Although infestations will be spotty, statewide population expected to 

 be greater than in any prior period. MEALYBUGS expected to enter high range 

 briefly in July, then gradually decrease. Population at summer peak will be below 

 normal. WHITEFLY populations predicted to be near normal and mostly at moderate 

 level. Decrease expected in August followed by an upward trend in late September.
