"Abstract: A new stabilized formulation of pyrethrins was field tested against larvae of the western hemlock looper by spraying from a helicopter. A selected number of larvae were placed in foliage on platforms were they were fully exposed to the spray and on small trees where they were partially screened from direct spray contact. Ninety-nine percent and 94 percent of the larvae on the platforms and on the trees, respectively, were paralyzed or killed by the insecticide. Most of the larvae fully exposed on the platforms were knocked down within a few minutes after spraying, whereas knockdown of larvae in the trees occurred over a considerably longer period of time. Recovery rate of paralyzed larvae was higher for those that were slow to be knocked down than for larvae knocked down quickly."

"Pyrethrin is a botanical insecticide that is extracted from a chrysanthemum, and it has long been a favorite insecticide use for quickly knocking down fly household insects. Screening tests at Berkeley revealed that this insecticide was very toxic to western hemlock looper but harmless to warm-blooded animals. Its main drawback is its instability. Pyrethrin will break down chemically very quickly when exposed to ultra-violet light. A stabilized form has been developed that will extend its insecticidal activity from minutes to a few hours. Stabilized pyrethrin was used in 1969 against a small hemlock looper outbreak on the Mt. Baker National Forest. Results looked promising for hemlock looper suppression but this insecticide had a heavy impact on aquatic insects which are food source for trout and young salmon. Precise application away from streams will be required in future control tests."

Today is my last day. I can't believe I made it the whole year! And I only missed three days.
This is the cake that Emily and I decorated for Terry's birthday. She baked the cake and put the chocolate glaze on it last night. My contribution was staying up until almost 3am last night making the stencils to use for the powdered sugar.
It actually worked out better than I thought it would, although there are a couple things I'd work on for the next attempt. Still, pretty sweet design, right?
I've shared the templates I made and written some very rough instructions in this photoset.
