The broad mite, Polyphagotarsonemus latus Banks (Acari: Tarsonemidae), was first noticed on greenhouse pepper cv Cleopatra and Sonar in Ie- rapetra (Southeastern Crete) in 1984. During 1984 there were scattered mite infestations in a few greenhouses but in the following years it has be- come an increasingly important pest of peppers.
The mite has been also found on cucumber cv Cnossos. aubergine cv Flaska and Solanum avic-
ularc (indigenous of Amazonios) in the greenhou- ses of the lerapetra Experimental Station. It atta- cks the growing points, young foliage, stem flo- wers and fruits. The growing points and bud are di- storted (Fig. l b ) , the young leaf margins down curl, the apical leaves crinkle, the leaf veins fuse and distort (Fig. Id) and the color changes to dark green, the fruits and stem crack and turn russet, mis-shape resembling like a fruit or stem scab (Fig.
lc) and finally the small leaves and flowers fall off.
Severely affected plants have little or no young growth, remain stunt and all fruitlets are aborted.
The general look of the infested plants is similar to those affected by hormone weedkiller (Gellatley 1969). Affected plants could not recover easily and the symptoms persisted for many weeks in spite of the acaricide treatments applied by the growers. In an artificial infestation of young pepper plants cv Sonar by 100-200 individuals, the symptoms of broad mite damage appeared in eight to ten days under growth chamber conditions (24±0.5°C, 60±5% R.H., 12.000 Lux for 16 hours daily).
In Greece, the broad mite was first recorded on cotton leaves in 1969 (Hatzinikolis 1970) and later on citrus trees (Hatzinikolis 1985). In Britain, it

A c c o r d i n g to Basset (1981) the spread of P. latus in m a n y g r e e n h o u s e p l a n t s in Britain was caused by the a b s e n c e of acaricide t r e a t m e n t s in g r e e n - houses w h e r e biological control against the t w o s p o t t e d spider m i t e Tetranychus urticae was a p - plied and the p r e d a t o r Phytoseilus persimilis w a s i n t r o d u c e d by F r e n c h b e a n leaves which was a r e - c o r d e d host of b r o a d m i t e ( G e l l a t l e y 1969).
T h e female longevity v a r i e s b e t w e e n 7-18 days d e p e n d i n g mainly on t e m p e r a t u r e . T h e m e a n n u m b e r of eggs/female is 40-50 (Martin 1983, Laffi 1982, B r o w n a n d J o n e s 1983). A c c o r d i n g to H u - gon (1983) the life cycle of b r o a d mite is c o m p l e t e d in 4 4 1 , 2 0 5 and 98 h o u r s at 1 4 , 2 4 and 30°C, r e s p e c - tively. T h e d e v e l o p m e n t a l r a t e of various stages of the mite increased with the t e m p e r a t u r e b u t decli- ned at a b o u t 35°C (Li Lung-Shu et al. 1983). T h e b r o a d mite has b e e n r e c o r d e d on a wide r a n g e of hosts: tea p l a n t , b e a n s , t o m a t o e s , c u c u m b e r , p e p - p e r s , a u b e r g i n e s , c i t r u s , z e r b e r a , fuchsia, j a s m i n - urn, m a g n o l i a , c o t t o n , j u t e , coffee, a v o c a d o e t c .
