Watch all the action from our recent #ADAMAAustraliaMotorbikeCropTrialsTour in WA. With over 25 agronomists and growers riding alongside the ADAMA Australia team combining their passion for crop trials and all things motorbikes, this really was a trial tour with a difference! #trials
Budworm are cannibals; We picked up this guy at Northam this week, then caught him munching down on his cousin. Adding the sound of a cat eating in the background really helps bring home the massacre. #pestfax Dusty Severtson Cindy Webster
We found a some budworm and predatory shield bugs on flowering radish. An attack on a full sized caterpillar failed then success with a smaller one. Two tubes (maxillae), 1 pumps saliva into the budworm, dissolving its insides the other sucks it back up. DPIRD Broadacre - WA Grains & Livestock @DPIRDWA

Brown lacewing, we are finding a few more of these now the weather is warming up. They are reported to eat up to 100 aphids a day, although this lady slowed down after devouring 2. So I've left her in a jar with 100 aphids to see how she does over the weekend. DPIRD Broadacre - WA Grains & Livestock
Head down and finding canola damage at Mingenew. The Dongara Weevil will chew on the hypocotyl at or just below the surface. tickle the soil and they will play dead if found, but get up and start moving within a minute. Mingenew Irwin Group DPIRD Broadacre - WA Grains & Livestock GRDC
There's a mysterious weevil damaging crops in the Mid West. Great to get out to Mingenew and put this all together in one day. Shoutout to Christiaan Valentine helping me get some wonderful macro shots of the little guys. 7NEWS Regional WA DPIRD Broadacre - WA Grains & Livestock Mingenew Irwin Group Murdoch University
