Abstract

Tuta absoluta (Meyrick), Nesidiocoris tenuis (Reuter) and
Bemisia tabaci (Genn.) activities on tomato plants at Fayoum
Governorate were evident during (nili and summer 2011/2012 &
2012/2013). The highest number of immature stages (larvae) of
T.absuluta occurred in November & December 2011 and 2012 (37 and
25 indiv./10 leaves) respectively during nili plantation , while the
numbers of this insect were decreased during the summer plantation
2012 , the highest number recorded on June (20 indiv./10 leaves).
There was highly significant correlation between the T.absuluta
population and mean temp. during nili plantation 2011 . On the other
hand, the highest populations of B. tabaci (97 and 70 indiv./10 leaves)
was recorded in 2nd and 4th week of Oct. during (nili 2011/2012) and
(81 and 64 nymphs/10 leaves) in 2nd week of June and July (summer
2012/2013), respectively. For N. tenuis, the highest number (47 ; 39;
50 and 39 individuals/10 leaves) occurred during 1st and 2nd week of
October during nili 2011 & 2012 and 2nd week of June, 1st week of
July during summer 2012/2013, respectively. Also, six species of
predators were recorded in association with tomato plants, Orius sp < /span>.,
Chrysopa vulgaris ,Syrphus corella, Coccinella undecimpunctata,
Mantis religiosa and Paedrus alfierii.
