A Laboratory study was conducted during 2010 on the biology of seed beetles: Callosobruchus chinensis, C. maculatus and C. analis (Coleoptera: Bruchidae) on lentil seeds for the first specie and chickpea seeds for the last two species. These beetles
completed 10, 8 and 5 generations respectively when they were active (from March to November for the first and second species and from April to October for the third species ). C. maculatus laid an average of 100.29 ± 18.26 eggs over a period of 11.14 ± 0.64 days, C. chinensis laid 83.29 ± 6.32 eggs over 6.43 ± 0.49 days and C. analis 75.29 ± 9.05 eggs over 6.71 ± 0.70 days. The total development process from egg to adult takes an average of 25.87 ± 3.29, 31.43 ± 5.09 and 35.36 ± 3.49 days respectively for species under the ambient laboratory conditions. There was no difference in the development time between males and females except for C. maculatus, where the male emerged about twelve hours before the female. Sex ratio (male: female) was more in favour of female than male in C. chinensis (1: 1.1) and more in favour of male than female in C. maculatus (1.1: 1), but equal in C. analis (1: 1).
The parasite wasp Anisopteromalus calandrae (Howard, 1881) (Hymenoptera: Pteromalidae) could be considered the first recorded on C. maculatus in Syria.
In this study, 200 Tittigoniids specimens were collected from 32 locations in Syrian
coast during 2012 and 2013 seasons. Morphological and taxonomical aspects of
collected specimens have been studied. Identification keys of families, genera,
and s
pecies were recorded according to the most important taxonomic features.
A total of eighth genera recorded and classified, and these were: Phaneroptera
nana, Phaneroptera sparsa, Acrometopa syriaca, Tylopsis lilifolia, Conocephalus
conocephalus, Conocephalus maculatus, Conocephalus concolor. The species
Isopya savigny was considered the first record in Syria.
