Fatty Acid Composition of Eggs during Development of the Cotton Leaf-Worm, Spodoptera littoralis Boisduval
Gas-liquid chromatographic analysis of egg lipids during development of Spodoptera littoralis showed the presence of 13 fatty acids ranging in carbon chain length from caproic (C6:0) to linolenic acid (C 18:3). Palmitic, palmitoleic, stearic, oleic and linoleic acids composed over 90% of the total fatty acids. Palmitic acid was always the predominant fatty acid and oleic acid was the second mos...
متن کاملOn the fate of methanol and ethanol in the adult larva of the cotton leaf worm (Prodenia litura F).
The metabolic fate of C-methanol and l-C-ethanol in the adult larva of Prodenia litura has been investigated in vivo. Following the intersegmental injection of C-methanol (1.2 mg/g. insect), about 70% of the radioactivity was recovered as C02 in the expired air, after 20 hours. Also, about one fourth of the administered dose was recovered as unchanged methanol, during the first six hours. Only ...
متن کاملWorm virulence estimation for the containment of local worm outbreak
A worm-infected host scanning globally may not cause any new infection in its underlying local network before it is detected and quarantined by a worm detector. To defend this type of scanning hosts, a number of worm scanner detection methods such as failed scan detection, honeypot, and dark port detection are proposed. However, for a stealthier worm limiting its scan inside an enterprise netwo...
متن کاملErratum: Development of insect resistant maize plants expressing a chitinase gene from the cotton leaf worm, Spodoptera littoralis
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...
