Broad bean plants have
an important status in human nutrition because they are rich in protein. In this study, harmful and beneficial insect
fauna on pods of broad bean were studied in a limited area. The study was carried out in the commercial broad bean
production areas in Çukurova region of
Turkey between the years 2014-2016. In each survey, 4-8 fields were visited to
determine the numbers of pest and predatory insect species. The size of commercial fields sampled varied from 0.5 to
1.0 ha. Sampling was carried out when plants were in the flowering-pod
formation stage. Insect species were sampled by beating the plants vigorously
into a white plastic container. A total of 14 harmful insects from 4 genera were identified. Western flower thrips, Frankliniella occidentalis (Pergande) dominated
the pest insect fauna (a total of 444 individuals) accounting 40.07% of the total number of adults. Relatively high numbers
of thrips and aphids were determined. A total of 9 predatory insect species
from 2 genera were recorded. The most
common predatory bug was Orius niger
(Wollf) accounting for 76.83% of total
adults collected. O. niger was often
detected with thrips species on flowers of plants. No damage due to insect pest
species detected was observed throughout the sampling periods. This study suggests that growing faba bean in
the winter-spring period, especially in agricultural areas having poor plant
diversity in the Mediterranean region, could be useful for conservation and
augmentation of beneficial insects.
