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

Found in an oat trial at Northam; a Western Scorpion fly using an unlucky budworm to attract a female. While the female is feeding, the male will attempt to mate with her. Thanks to the team at MyPestGuide reporter for helping me identify this one. agric.wa.gov.au/apps/mypestgui…

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

We installed a pair of Bioscout automated spore monitors at South Stirlings last week. Thanks to the Team BioScout for coming over and setting these up. These will capture daily data and identify any disease buildup in the region. iMapPESTS DPIRD Broadacre - WA Grains & Livestock

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

Amber Balfour-Cunningham Amber BC comparing budworm pupae development in lupins and wheat. Unlike Diamondback moth which pupate in mesh cocoons on the plant, budworm pupate in the soil. Notice it trying to bury itself when uncovered. GRDC DPIRD Broadacre - WA Grains & Livestock

Weekly budworm moth flights from our trapping network - June to now. Get those sweepnets out and consider traditional thresholds to be on the low end with the current grain prices. More info in this weeks #PestFax, iMapPESTS DPIRD Broadacre - WA Grains & Livestock GRDC West

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
