Examples include: Spiders; Pale Green Assassin Bugs; Ambush Bugs; Green Leafhoppers; Sweat Bees; Zelus luridus (Hemiptera) These insects, including Zelus luridus, hunt and feed on harmful pests, like the Dogbane Leaf Beetle, in various ecosystems ...
29 lip 2024 · The dogbane beetle has a crafty trick to rid itself of this sticky mess. After nibbling for a while, the dogbane beetle does a moon walk while dragging its mouthparts on the leaf to wipe-off the sticky dogbane latex. Once free of the latex, it moves to a new spot to resume its feast.
10 paź 2013 · In laboratory bioassays, we found adult dogbane beetles were highly susceptible to field rates of phosmet (Imidan) and acetamiprid (Assail) by direct topical contact and ingestion of treated foliage, whereas no mortality was seen with spirotetramat (Movento) and chlorantraniliprole (Altacor).
24 sie 2010 · This cache of toxins is available to spray on persistent/callow predators, who may get a face full of the noxious goo. Plan C calls for these beetles bail, drop to the ground and hide among leaf litter when disturbed.
2 lip 2020 · In blueberry fields, nicosulfuron mixed with surfactant suppressed spreading dogbane (>60%), and dicamba spot sprays were over 80% effective. Glyphosate spot sprays worked better than hand pulling, and wiping with glyphosate was also effective (Wu and Boyd, 2012).
The dogbane beetle could be an alternative to control the spreading dogbane. In high densities, this beetle can eat up to the 40% of the dogbane foliage ( A. androsaemifolium ), a weed of blueberry in eastern U.S.A. and Canada.
16 kwi 2018 · A Canadian study by Boyd and Wu (2012) observed more consistent top-growth control of dogbane when Distinct (diflufenzopyr/dicamba), Infinity (pyrasulfotole/bromoxynil), dicamba (Engenia/Xtendimax) + 2,4-D LV Ester and glyphosate were “spot sprayed” compared to broadcast applications.
