Sugar shaking bees is a method used to detect external parasites, such as varroa mites, tropilaelaps mites and braula fly on European honey bees (Apis mellifera).

During flowering growers are faced with managing both beneficial insects and pest insects. Beneficial insects are crucial for pollination and are a major asset for industry stakeholders (beekeepers). Flower pest insects, such as lace bug or flower caterpillar, can cause extreme yield losses (from 50-90% losses). These factors combine to create a challenging situation for macadamia growers to manage.

Maximise your macadamia crop with better pollination. Many varieties of macadamias produce more nuts when cross pollinated with another variety.

Do you know how much pollination is happening in your orchard? This is an important question because good pollination can increase both nut set and dry kernel weight. This article summarises how you can better understand how much pollination is occurring now, and what you can do to improve it.

Research has shown the beneficial effects of cross-pollen of macadamia varieties compared with self-pollen, but there is little research comparing varieties as pollen-parents. The aim of this study was to determine how cross-pollen from commercial varieties affects fruit development and mature nut properties, particularly the economic parameters of nut size, kernel weight and kernel recovery

The aim of this research by Southern Cross University was to identify the sources of pollen that produce seed, i.e. who is fathering the nuts. Preliminary, unexpected, results showed that almost a third of the mature seed in each year was self-fertilised. More work is needed to understand whether this level of self-fertilisation is unusual or more widespread. The results may be helpful for future cultivar selection and orchard design.

Pollination is an ongoing area of investment for R&D, however, research to date has been inconclusive. Two industry experts put their views about the key pollinators in the orchard and how to optimise cross-pollination.
