This clause zeroes in on bamboo wanderer mites . Read on and learn what to look for and how to manage an plague .

What You’ll Learn
What Are Bamboo Spider Mites?
Mites are sap - sucking pests , and although they are tiny , valuate less than 0.04 column inch long , they can do serious damage and compromise the ornamental time value of plants .
Numerous mites in multiple taxonomic genera provender on bamboo .
In one study , 45 species from 23 genera and nine taxonomic families were collect from moso growing in Fujian , China . Common moso , or tortoiseshell bamboo , Phyllostachysedulis , grows alfresco in USDA Hardiness Zones 7 to 10 .
The mites that do the most terms to bamboo are in the following families :
Stigmeopsis(syn . Schizotetranychus ) is a spider mite genus in the Tetranychidae class mentioned above .
family Tetranychidae is a subclassification of the Acari , or mite order of insect . Stigmeopsisspider mites are the most destructive bamboo pests in the macrocosm .
One type of family Tetranychidae isStigmeopsis longus .
It favor bamboo in theSasagenus , likeS. veitchii , known as kuma bamboo grass or Nagasa bamboo . This type grow outdoors in Zones 6 to 9 .
In addition toPhyllostachysandSasa , other host genera forStigmeopsisareIndocalamus , andPleioblastus .
Bamboo Spider Mite Identification
Stigmeopsishave eight legs , a flattened pale yellow to greenish - yellow body , and greenish - calamitous spot .
They live on the underside of the leave of absence , mostly beneath white webbing . Frass , or black excreta , may be visible near the net nests .

Extensive colonization and feeding via media decorative value , and in uttermost cases , may lead to plant death .
Bamboo Spider Mite Biology and Life Cycle
In quick climates and indoors , spider mites stay active year - circular . They only cease mate when the temperature fall below 52 ° F .
In coolheaded clime , they go into a semi - dormant state prognosticate diapause . As the days grow shorter and winter plan of attack , they cease feed and multiply and seek shelter in available crevice .
It is fascinating to note that the female shade to bolshy for the winter , a color that often signify danger in nature . What a capital mode to safeguard the species during wintertime sleep !
When spring come , the days grow longer , the temperature increases , and the pests reemerge .
Once they square up on a host plant , the adult colonize the underside of leaves , prey , conjugation , lay eggs , and insure their territorial dominion with a thick , blanched cottony web .
adult , unseasoned nymphs , and larvae may be visible outside the webbed colony , moving a distance from it to defecate .
