Are plants conscious? “We tend to think of plants as passive organisms, the backdrop for looking at more interesting animals roaming around in the foreground. But the world of plants is by no means docile, it is simply working on a separate time scale and in a different medium, and we’re only just starting to decipher it.” (Josh Davis, iflscience.com) https://bit.ly/2pQZjwr
Red meat allergy associated with tick bites could also be passed on by tiny mites. “After a series of strange medical cases, researchers discovered that bites from the lone star tick can induce a severe and persistent allergy to red meat. In the six or so years since this was identified, it has been determined that bites from multiple other tick species can also cause it. Now, evidence indicates that bites from another type of small, parasitic arachnid known as a “chigger” may do the same.”(iflscience.com) https://bit.ly/2zLQokc

How do insects, like aphids survive on a high sugary diet? “There’s a reason parents tell their kids to lay off the sugar: too much isn’t good for you. But small sap-sucking insects called aphids can survive quite nicely on a largely sugar-based diet, despite their inability to make important nutrients from scratch. The key to their success is symbiotic bacteria, which live inside aphid cells and make amino acids, the building blocks of proteins needed for growth.” (University of California, Riverside via lab.manager.com) https://bit.ly/2MgkWjs

The conclusion of a report from Newcastle University about the removal of neonicotinoid for use in seed treatment of oilseed rape… “Insecticidal control of CSFB in the past has relied on a combination of seed treatment and foliar sprays. The absence of neonicotinoid seed treatments is making CSFB control more challenging for farmers with significant losses of crop identified in the autumn of 2014. The estimated 33,957 kg of a.s. used in the autumn to combat the threat of CSFB represents a 2.5 fold increase in the use of autumn insecticides to WOSR in England and is likely to be a direct result of the ban on neonicotinoid seed dressings. The increased use and reliance on pyrethroids for CSFB control has significant future implications since resistance has now been identified in the UK. The loss of neonicotinoid seed treatments poses a significant challenge to growers at a time when significant price reductions have occurred in the value of this crop, together with an increased threat from the fungal pathogen light leaf spot raising the question for many farmers as to the true value of oilseed rape in the crop rotation.” Read the study: https://bit.ly/2JwanHz

The gelatinous looking tongues on the seeds of “Dicentra cucullaria, Dutchman’s Breeches, … are the elaiosomes. “They are rich in fatty lipids and proteins and meant for ants. Ants carry the seeds off into the ground, eat the fatty package and then leave the seed planted and ready to sprout when the time comes. This relationship is called myrmecochory. myrmeco=ant, chory=dispersal. Fun fact: Anthropochory is human dispersal of seeds, like when seeds stick to your pant leg. Many different plants, including Wild Ginger, trilliums and other Dicentra species like the more common Bleeding Heart, Dicentra formosa, have this relationship and produce elaiosomes. Ants are gardeners too.” (Humblerootsnursery, Instagram) https://bit.ly/2Kg82Ao

THIS MYTH BUSTED!“Sometimes concepts that are spread via social media and web pages that are just too juicy to pass by such as this “Easy at Home Soil Test”: “… Soil, Plant Pest Center tested several acidic soils and several alkaline soils submitted to the center and testing was complete. They followed the directions for this test using vinegar (weak acetic acid) or baking soda (sodium bicarbonate). Each soil was mixed with either vinegar or baking soda + water.
The results were as follows: 1. None of the acidic soils bubbled when baking soda + water was added; 2. Most of the neutral to alkaline soils did not bubble when vinegar was added. There were a few exceptions. Debbie pulled two soils with pH readings of over 8.1. One bubbled vigorously when vinegar was added; the other, also with an 8.1 pH did not bubble. In general, the test did not work as advertised. To be honest, if it had worked, it still would have yielded very little information. If it had worked, it would not have given the degree of alkalinity or acidity.
If you want reliable information about soils, use a professional soils laboratory that’s certified by meeting industry standards”… (Extension Master Gardener, Facebook) https://bit.ly/2rzDnHu

It also keeps her safely anchored to the roof of the queen cell in which she develops.” (Julia Kurtz via The Garden Professors Blog, Facebook)
