NEW TECHNOLOGY TO FIGHT VARROA MITES

WEEDS, WEEDS, WEEDS

Varroa mites are a large concern to beekeepers and can cause widespread devastation to hives. In the USA they have developed RNA technology to target the varroa mite to find out more follow this link https://www.youtube. com/watch?v=2YdM54bRZGw

We know that wines are savoured for their variations of sweetness, acidity, tannin, alcohol and body and these are influenced by environmental factors where the grapes are grown. It is hoped that soon there will be a similarly descriptive taste vocabulary for New Zealand honey. Manuka honey is well known and is a high value export product. It is hoped that the “Flower to flavour” project will give other varieties the same opportunity.

1 What are varroa mites? 2 How do they affect bees?

STRETCH YOURSELF:

Weeds are an ongoing issue for farmers and things have been compounded by recent discontinuation of certain herbicides and supply issues with others.

Interestingly from as far back as the 1890’s agronomists have been theorising that electricity could be used to shock weeds and halt growth. Original inventions were unwieldy, large and dangerous. However, a Massey University PHD student and professor has proven that small doses of electricity can provide good control of a variety of weeds across New Zealand pastures and crops.

Do some research, in NZ are varroa mites a large issue? In NZ what is currently used to combat varroa mites? What is RNA? How does using RNA technology give us the ability to target just bees and not affect other insects? How long have they been testing this technology? How effective is it? When is this technology expected to be internationally available? U.S. beekeepers lose approximately 40% of their honey bee colonies each year. The varroa mite is a leading cause of honey bee mortality.

Head to https://www.farmersweekly.co.nz/ research-to-put-honeys-taste-on-tongues/ and then answer the following questions: 1

What makes manuka honey different from other varieties?

2 What are researchers aiming to find out? 3 What will they be collecting? What are they extracting? What are they measuring from this? 4 What is the issue with labelling honey based on taste? Why is it problematic? 5 What will they use to analyse the chemical profile of the nectar’s? How do these work? 6 How many flowers are they hoping to collect samples from? Why would they need this many?

In this edition Rebecca talks to Delwyn Tuanui from the Chatham Island Food Co and how he chased his dreams from the ground up. From running around Melbourne with a chilly bin of blue cod, knocking on the doors of the city’s best chefs, he knew that he had a top class product.
