Abstract EN
This work was carried out during 2017 Berseem growing season to evaluate the effectiveness of chlorantraniliprole (coragen), emamectin benzoate (proclaim), profenofos (Cord 72% EC), spinosad 24% E.C and chloropyrifos 24% (Chlorosan) as foliar applications at the recommended rate against the cotton leafworm, S.
littoralis (Boisd.) on Egyptian clover plants.
Also, Survey of insect pests and natural enemies associated with Egyptian clover, or berseem, Trifolium alexandrinum plants were conducted to study the side effects of insecticides on interspecific diversity and equitability of entomophagous after application with the tested compounds.
Results showed that, the average reduction percentages after applications against S.
littoralis were 75.8% for coragen, 68.7% for cord, 65.9% for proclaim, 57.3% for chlorosan, and 52.4% for spinosad.
Spodoptera littoralis, bollworms and Aphis gossbii are very important species which cause economic loss in the Berseem crop.
Coccinella undecimpunctata, Trichogramma toide app, Apis mellifera L and Vespa orientalis were the most important natural enemies and pollinators which associated with Berseem plants.
The diversity index value after application with proclaim and spinosad were higher in the application with the insecticides followed by cord, chlorpyriphos and coragen, respectivily.
The result of proclaim showed high selectivity when compared with the other pesticides.
As for equitability it is obvious that the compared with the other of equitability higher values in the treatment of proclaim especially after 3 weeks post treatment.
The value of equitability reachd an environmental maximum.
In conclusion, it could be suggested that Proclaim showed toxic effect against bollworms and had a selective effect on the beneficial insects in Egyptian clover, T.
alexandrinum.
