Colorado Potato Beetle

[Durgan]

http://www.durgan.org/2015/June 2015/17 June 2015 Colorado Potato Beetle/HTML/ The Colorado Potato Beetle has surfaced on my potatoes. These are pictures of the hatched eggs, no adults have been seen to date. Due to my small number of plants they are hand picked as necessary for control. They cannot be ignored since complete destruction of the foliage will result is allowed to mature.

I am not growing potatoes this year but the adult Colorado Potato Beetle has been having a feast on my tomatillos. I haven't seen any of the larvae but have been searching for them. Spinosad seems to work well on the adults if applied about every 7 days. I don't know if it kills them or just runs them off

Such a tiny thing but is so capable of destroying the entire foliage in very little time! I haven't seen this sort of bettle, but we have Japanese bettle around. I watched one of this insect chowing down a entire leaf of my black-eyed Susan in just minutes!

Glad you found them in time!

Woah, that thing looks nasty. I have a thing for bugs, specially beetles and is not even a good thing to start with! So far I haven't encountered one of those, and I hope it stays like that Good job finding those!

To my knowledge the Colorado Potato Beetle is located almost every place in NA. It has many host plants but prefers the potato. One egg bearing female can infest an area in one season under the right conditions. Commercial growers use chemicals. Prior to 1945 everybody used Paris Green to control potato bugs, which is an arsenic based poison.DDT was effective, now banned. Now there are many chemical controls all harmless of course.
