Abstract

This study was carried out in Beni-Suef district to study the
effect of cultivars, some climatic factors and plant age on the
population density of Thrips tabaci Lind. on two recommended
garlic cultivars, Balady and Chinese throughout two successive
seasons 2006-2007 and 2007-2008.
The results revealed that the highest infestation rate of T. tabaci
was recorded on Balady cultivar, as the corresponding mean number
of nymphs and adults were 82.94 and 11.12 individuals / plant in the
first season and 62.91 & 11.71 individuals / plant in the second
season, respectively. The lowest mean number of T. tabaci was
recorded during first period and increased gradually to reach the
maximum number during the second period. Positive relationships
were recorded between the population density of T. tabaci and the
developmental stages of plant. The population density of T. tabaci
nymphs and adults were negatively correlated with maximum and
minimum temperatures. On the other hand, the mean of R.H was
affected positively on the population of T. tabaci in the two
investigated years. In the first season, climatic factors were more
effective on T. tabaci population nymphs and adults, as the CD
(Correlation Coefficient of Determination) were 68.55 and 78.97 %
for nymphs and adults on Balady cultivar and vies versa in the
second season.
