Hi Mark

Thank you very much for your help ,after searching in Google , I find that this insecticide is used to control bulb mites in other countries .I will buy it ,

about your question for wild bulbous plants in Shiraz to Khorramabad , i know that Fritillaria imperialis (Red and yellow forms) grow well at there but in mountains but i think that some of wild tulips grow at there too because tulips grow at many places of Iran and we just have to know the best time and best place to find them .
In north west of Iran under Azerbaijan Republic (where i live) we have not Fritillaria imperialis but other rare Fritillaria species ,wild irises and wild tulips exist in mountains .our climate is very cold in winter .
Hope this information help 
if i find more information in future i will write you .
Best Wishes

Dear Mohammad,
As you have observed, pyrethroid pesticides can exacerbate mite problems. Bulb mites survive in the soil feeding on plant debris, so killing mites on the bulbs with hot water treatment may only give very temporary relief. If available, I would suggest dimethoate. It is a systemic organophosphate pesticide that is generally effective against mites. 

My climate is similar to south western Iran from Shiraz north to Khorramabad. Can you recommend bulbous species from this region? I am particularly fond of tulips but my climate appears to be too warm in winter for most tulips. Are there tulips in south western Iran?
