Insects and Spraying???

pgde(Tucson Zone 9)December 11, 2012

Hi All:

Several questions:

1. Is this a good time of the year to spray non-blooming citrus with hort oil? I was thinking that since the temps are now more moderate, this might be good to attack eggs, etc.
2. I have a supply of Neem oil. Does Neem oil = horticultural oil and can it be substituted?
3. Some insect is attacking the fruits of my Naval Orange tree and my Star Ruby Grapefruit. Whatever it is drills a perfectly round hole in the fruit about 0.5 inch in diameter and when one shakes the fruit, a swarm of tiny insects come flying out that have transparent wings, black (or dark) bodies and are about 1/16" to 1/8" in size. What is interesting is that they do not attack either of my lemons or my lime tree. Any ideas or what to do? I don't have any pix since I wanted to destroy the fruit ASAP. Will try to remember to get pix next time....

Thanks all for your help.

Happy holidays!

The hole and the insects are likely not related; without a photo I would venture to guess that the hole is made by a bird and the insects are just taking advantage of the easy access to sugar.
