Neonicotinoid insecticides can serve as inadvertent insect contraceptives | Proceedings of the Royal Society of London B: Biological Sciences
There is clear evidence for sublethal effects of neonicotinoid insecticides on non-target ecosystem service-providing insects. However, their possible impact on male insect reproduction is currently unknown, despite the key role of sex. Here, we show that two neonicotinoids (4.5 ppb thiamethoxam and 1.5 ppb clothianidin) significantly reduce the reproductive capacity of male honeybees (drones), Apis mellifera. Drones were obtained from colonies exposed to the neonicotinoid insecticides or controls, and subsequently maintained in laboratory cages until they reached sexual maturity. While no significant effects were observed for male teneral (newly emerged adult) body mass and sperm quantity, the data clearly showed reduced drone lifespan, as well as reduced sperm viability (percentage living versus dead) and living sperm quantity by 39%. Our results demonstrate for the first time that neonicotinoid insecticides can negatively affect male insect reproductive capacity, and provide a possible mechanistic explanation for managed honeybee queen failure and wild insect pollinator decline. The widespread prophylactic use of neonicotinoids may have previously overlooked inadvertent contraceptive effects on non-target insects, thereby limiting conservation efforts.
Deputies: Laurel Co. DUI crash led to bee attack
The car crash was bad enough, but investigators say it led to two people inside the vehicle being attacked by a swarm of bees from a disturbed hive.

This is to inform you that you may have to reenter your username and passwords if you use a password manager. I just upgraded us to use SSL so that no one(except maybe the NSA..heh) can listen in on users logging into the system. This will make us much more secure. The reason why you may have to relogin is because the “http” changed to “https” and some password managers think that’s a brand new site(and they should)

Royal Jelly Isn’t What Makes a Queen Bee a Queen Bee
Everything we thought we knew about royal jelly is backward.
Plants have a complicated relationship with bees: They need the insects to spread their pollen, but—because pollen takes a lot of energy to make—flowers need to make sure each bee doesn’t take too much. Now, new research has shed light on how plants control how much pollen each bee extracts from them—taste, according to a study published today in the journal Biology Letters.
Sweet success: how bees choose which pollen to collect
Study shows that bees use the taste of pollen to tell
Many(though not all) of the old blog posts have been added to the site. I removed some of the announcements about Bee School because I didn’t want it to confuse anyone who was just joining us but many of the articles, links, etc. are available on the site now.
We have a new website that is now (mostly) working. The web address is http://www.bluegrassbeekeepers.com
First of all, the classified ads aren’t working until after the next meeting because we have to discuss some things regarding payment. So if you want to put up a classified ad, you’ll just have to wait a couple weeks.
Our forum is operational. You will need to create an account on the system and it will let you post questions, etc. I will be adding things to beef up the security in the next few days so if it asks you to verify one of those “CAPTCHAs”, it’s because we’re trying to make it rough on spammers.
If you would like to contribute to the site either by posting to the blog or submitting news, contact an administrator on the FB page and we’ll get you setup. The same goes if you have suggestions for things you’d like to see on the site. A calendar of events is already in the planning and should be up soon.
