JimmyBoof Posted December 19, 2014 Report Share Posted December 19, 2014 Has anyone had to deal with mites on Myrmecodia and Hydnophytum? they don't seem to be causing much damage, but they are present. Thanks! Quote Link to post Share on other sites
Andreas Wistuba Posted December 19, 2014 Report Share Posted December 19, 2014 I grow my Hydnophytinae together with Nepenthes in the same greenhouse. Nepenthes easily catch mites quite easily. So I spray against mites from time to time. No negative effects for the ant plants. All the best Andreas Quote Link to post Share on other sites
Stone Jaguar Posted December 20, 2014 Report Share Posted December 20, 2014 Yes, both Hydnophytum and Myrmecodia spp are quite vulnerable to spider mite infestations. Those with non succulent leaves are particularly attractive to spider mites. Like Andreas, I grow my hydnophytines alongside other plant families that may be spider mite magnets, so I spray regularly together with a behaviour modifying substance to move males out from the lower leaf surfaces. If you do spray, remember to rotate at least three chemically unrelated miticides to avoid developing pesticide resistant mites. Predatory mites as an environmentally neutral alternative are very effective in large collections where they can move about and maintain at least a residual permanent presence. in most small collections they will die out after they have consumed the existing pest mites, necessitating reintroductions on a regular basis. They are not inexpensive at retail level. I have released several types of arthropod biocontrol agents over the years and find their effect to be positive, but ephemeral. They are, obviously, susceptible to most insecticides to varying degrees. J Quote Link to post Share on other sites
