Bee the Best!

Value of honey bees in Michigan from pollination service and honey production 01/03/2017
Tweet Value of honey bee pollination in Michigan, based on 2015 data The Western honey bee Apis mellifera plays a crucial role for US agriculture because it provides pollination for a large number of crops. The value of agricultural crops dependent on honey bee pollination was estimated to be $14.6 billion per year in the […]
Adjusting control mortality in LC50/LD50 determination using R 12/06/2016
TweetProblem: There are R codes for calculating LC50 or LD50 using 4 to 6 data points. However, none uses control mortality correction (e.g. Abbott correction). There is an ecotoxicology package which does this, but it seems hugely complex to use. Solution: In the code below, we put the last line as the control mortality (dose=0), […]
Late August honey plants: Rhus chinensis. 09/05/2016
TweetAugust and Sept is a tough time for honey bees. Goldenrod is starting but not going strong yet around late Aug so honey bees are always trying to find something good for them. Two good plants bloom around this time: China sumac and seven son’s flowers. I noticed last year (Aug 22) that a large […]
Honey bees foraging on catalpa leaves 07/31/2016
TweetThere was on post (June 23rd, 2016), I was begging everyone to show me if they saw honey bees foraging on catalpa leaves. No one responded. On Sunday June 26, I finally had the luck to see honey bees foraging on the back of catalpa leaves. I was going to give up after waiting for […]
False queen in a laying worker colony 07/30/2016
TweetAt the Friday lab meeting, I was told that one colony has become all “laying workers” by a visiting scholar in my lab, so I decided to take some photos the same day. I have seen workers backing into cells before, to lay eggs but at that time I did not have a digital camera […]
A bee on a bee balm 07/19/2016
Tweeta bee who is calm, she worked on a bee balm. i asked did she see it as pink? she shook her head, and gave me a wink. Chinese translation: 一个小蜜她不恼不慌不忙她采管香蜂草 “小蜜那花你看也是粉色的么” 她头摇一摇，竟把媚眼抛
A bee foraging on crososmia (Iridaceae) 07/19/2016
Tweet(rewritten from “the lady in red”) The crocosmia sings: You are dancing with me I become red, cheek to cheek There’s nobody here I hide, you seek You bury deep in me To take all my honey But I hardly know that your beauty is so bright It outshines the sunlight 1. 2. 3. Chinese […]
Bees foraging on catalpa leaves, anyone? 06/23/2016
TweetOk, I have seen bees foraging on catalpa flowers, many years ago. In fact here are some pictures I took, in 2005 (date stamp: 2005-06-18 10:31:24). I remember this was in Okemos, behind the Quality Dairy Store near Grand River and Dobie. At that time I did not notice that catalpa leaves also have extra-floral […]
Bee vampire picks the right host to suck 06/15/2016
TweetContact(s): Mark Kuykendall , Zachary Huang New insights into the reproductive secrets of one of the world’s tiniest and most destructive parasites – the Varroa mite – has scientists edging closer to regulating them. “If you know your enemies better, you can come up with new ways of controlling them,” said Michigan State University entomologist […]
Survival analysis in R: time-saving method 2 05/17/2016
TweetThis blog continues from last time, in trying to generate “long data form” required by R (or any survival analysis, for that matter, such as SAS or SPSS), from “short data from” which is easier to input and can reduce errors. Using “times=N” last time was not very neat, so this is another method, looping […]
