I think there's a difference from living rural/semi-rural to city - I live in a city and hubby and I were talking about the lack of bugs here. I wonder if the spray the use to control mosquitos is having a negative effect on other bugs.
No not always
There's no spraying around here, no herbicides or pesticides at all, I wondered if it being my 2nd year with honey bees if that hasn't affected the valley's balance, seems there's more of everything now. The butterflies are crazy this year, swarms of them where before I might see the odd one. Way more bugs too.
I think it might be as UofA Prof Schindler said, that imbalance is the normal and the last 100 years or so has been a period of unusual stability.
You know, I have to research exactly which chemicals they are using here, however they all seem to be in the pyrethrin family, which kills a wide range of insects as per this article.
Quote:One of the products being used is Anvil®. The active ingredient (ai) in Anvil is Sumithrin, a member of the pyrethroid family. It is highly toxic to honey bees, as indicated by its LD50 value. The LD50 is the dose at which 50% of an exposed population is killed. Sumithrin has an LD50 of 0.06743 ug/bee (one ug = 1 millionth of a gram). A second product being used is Scourge®. The active ingredient in Scourge is Resmethrin. It is also a pyrethroid and is highly toxic to bees, with an LD50 of 0.063 ug/bee. Both compounds have very short half-lives in the field.
