NOW MONITOR
Newsletter February 2009
The improved NOW Monitor (Navel Orange Worm (NOW) pheromone monitoring lure) is ready to go in 2009. We are now offering exclusively the 3-piece lure.
The 3-Piece lure. 3 black rubber rectangles tied together with a paper clip. Do not separate these 3 pieces. Place the whole lure inside the trap as shown below.
Do not separate the lure. Keep all 3 pieces together on the paper clip.

We are no longer using the red rubber septa lure. They are not as biologically active as the 3-Piece lure and catch much fewer NOW moths. See trap capture data from 2008 on this site. The new 3-Piece lures caught many times more NOW months than the red rubber septa
The Red Rubber Septa lure. These are no longer offered.
How to use the NOW Monitor Lure:
The NOW Monitor 3-Piece lure attracts and captures the male NOW moth. What you have in the traps are male moths attracted to a calling female. You are not capturing female NOW with this lure !

Our trap capture data in 2008 indicated the following:
| A - | The NOW flight starts from late March to early April and lasts until late May or early June. |
| B - | There is a period of low to zero capture of the months from mid-June to July. |
| C - | In mid-July or so the 2nd flight starts and there is fairly continuous flight until the flight stops in October. |
What We Have Learned from the Trap Capture:
| A - | The higher the trap capture numbers the greater your potential problem |
| B- | Low trap capture can be construed as having low in-field populations of NOW. Note the word in-field. The NOW Monitor lure may or may not be accurate for “fly in” moths from outside your orchard. |
| C - | The NOW Monitor lure can be used to time a “hull split” spray. Monitor the first generation of NOW and count your degree days. |
| See Navel Orange Worm - the Insect and note how the insects develops with different degree days on different crops. | |
| D - | Note the period between the first generation and the second (Mid June into July). If you are capturing male moths during this period (even at a low level) you have a high population in the field. This is a critical time to monitor, especially in problem orchards. |
| E - | The trap capture in the second and third flights is a good indication of how well your “hull split” spray killed the NOW. |
| F - | Trap capture in the second and third flights can tell you how critical it is to harvest your crop before NOW damage becomes a problem |
| G - | Year to year data can show you how well your winter sanitation program is. |
The NOW Monitor 3-piece lure lasts 3 months !
They come in packages of 25. The lures should be stored frozen until used. In the freezer they will remain viable for several years.
