Demographic parameters of the pink stem borer, Sesamia cretica Lederer (Lepidoptera: Noctuidae) were estimated on its two main host plants, maize and sugarcane. The present study was conducted under laboratory conditions at 27±1 ̊C, 50±10% Relative Humidity (RH %), and a photoperiod of 0:24 (L:D) hour for the larval stage and 16:8 (L:D) hour for the other life stages. The raw data were analyzed ...

Background: Maize plants are infested with many insect pests. The corn borer, namely: the greater sugarcane borer (the pink borer), Sesamia cretica Led. is one of most injurious insects infesting maize in Egypt and all over world. Results: Results illustrated that mortality percentage within 48 hours S. after feeding 4th instar larvae on leaves treated various plant extracts alcohol or petroleu...

The current research was performed aiming to investigate the effects of Ferula ovina essential oil on the fourth instar larval hemogram of Sesamia cretica. Four main sorts of circulating hemocytes, including prohemocytes, plasmatocytes, granulocytes (GRs), and oenocytoides, were identified in the fourth instar larvae. Treatment of the larvae with the concentration of 1000 ppm of the essential o...

Due to the importance of chitinolytic enzymes for insect, nematode and fungal growth, they are receiving attention concerning their development as biopesticides or chemical defense proteins in transgenic plants and as microbial biocontrol agents. Targeting chitin associated with the extracellular matrices or cell wall by insect chitinases may be an effective approach for controlling pest insect...
