Forlimnlcly the Pink Bolhvoiiii is noi CMiliicly 

 wilhoiit parasites; a large, handsome Hynienopteron 

 a species of Piniphi has heen l)red (Vom it l)y Dr. 

 Gongh Entomologist to the Department of Agricultiiie 

 and also hy myself. 



Within the past fortnight or three weeks the 

 predaeeons acarine or mite known as Pedicnloides 

 ^■ent^icosns Newpl. has l)een fonnd to he ((nile 

 conimon on Pink ßollworm larvae infecting a sample 

 of cottonseed i-eceived from lâchera j)rovince. This is 

 not the (irst record of Pedicnloides occnring in h-gyid 

 as in a })revions commnnication I have noted its 

 ])resence here on the following hosts : Brnchns 

 chinensis, Earias insnlana, Prodenia lilloralis and 

 the i)npa of a Bnpreslid heetle. 



At first I hoped that this mite might be an 

 important enemy to delechia gossypiella ; hnt now I 

 donht if it can do veiy mnch in this direction. To 

 he elTeclive il must be able to attack easily the pest 

 in the field, bnt its powers of doing this — ^jndging l)y 

 its work against the Mexican Bollweevil in America — 

 are likely to be very ver}' limited. However it may 

 be moie eileclive in the case of the Pink Bollworm 

 passing the winter and spring in the dead bolls on 

 coltonsticks in hea[)s in the fields and on the top of 

 honses bnt this remains to be proved. Now as regarils 

 its iniportance when it attacks the Pink Bollworm in 

 cottonseed: for rapid increase it seems to re(|nire a 

 fairly high tenn)erature and this temperatnre is not 

 reached nnlil all the cottonseed has been sown and 

 moreover as we have fonnd that the best tagawi 

 contains Aery few seeds infested with Pink Bollworm 

 it would thus have dillicullv in cominu into contact
