The comparative study on the composition of fatty acids and sterols in the seed oil of four forms of Roselle (Hibiscus sabdariffa L.) cultivated in Egypt was carried out. The total oil content in the seeds of the investigated forms ranged from 15.31 to 18.99?á. As a result of the GC analysis five fatty acids were identified: palmitic, stearic, linolic, y-linoleic, and a-linoleic acid. The forms differed both in respect of the presence and the content of particular fatty acids. The HPLC analysis indicated the presence of four free sterols in the Roselle seed oil: brassicasterol, campesterol, stigmasterol and sitosterol. Sitosterol appeared to be the main sterol and its content depended on the form of Roselle.

Root-knot nematode Meloidogyne incognita (Kofoid & White) Chitwood is an economically important pathogen of many agricultural crops, and the frequency of occurrence, abundance and importance of this nematode in resource-poor agricultural production systems make control necessary. Field studies were conducted in 2004 and 2005 to determine yield loss of Roselle due to natural infestation by M. incognita using Carbofuran 3G at 2 kg a.i./ha and untreated as check. The yield of Roselle was found to be higher with the application of nematicide-Carbofuran 3G at 2 kg a.i./ha. The percentage increase over control was 48.7 and 40.8% in the years 2004 and 2005, respectively. A significant reduction in the yield of Roselle in untreated plots was mainly attributed to direct damage of the root system by the feeding of root-knot nematode M. incognita. Root-knot nematode population in carbofuran treated plots was significantly lower than in untreated check in the two years, also at harvest. In the check the nematodes multiplied many folds during the cropping season. High nematode population in the untreated check decreased plant growth and ultimately reduced the number of seeds and weight of seeds.

This paper presents a preliminary report of Fusarium wilt of Roselle in the Nigerian savanna. Soil and plant samples were collected from eight experimental plots where plants showed Roselle wilt symptoms. Samples were analyzed for the presence of nematodes and wilt pathogens. The wilt causative organism Fusarium oxysporum was isolated together with nematodes of different genera. However, nematodes of the genus Helicotylenchus, Scutellonema and Hoplolaimus appeared to occur in higher densities than the others.

Natural enemies of insect pests in vegetable crops (brinjal, okra and tomato) were recorded and their diversity was studied in Kancheepuram and Tiruvallur Districts, Tamil Nadu. Natural enemies were collected by pitfall traps, sweeping nets and by hand picking from January 2011 to December 2013 twice in a month. Totally 129 species of predatory and parasitic insects were recorded. All the natural enemies were grouped into 50 families under eight different orders. Order hymenoptera contained the highest number of families and species. Among the predators, Coccinellidae (ladybird beetles) was found to be the dominant group with high number of species. It was clear that Coccinellidae, Staphylinidae, Carabidae and Pentatomidae were the predominant natural enemies throughout the study period. In 2013, formicidae formed the major family of occurrence from July to December in the vegetable fields; in this period the total number of individuals collected from all families was the highest. The maximum Shannon-Wiener diversity index was 3.70 during the second season in 2013. Maximum richness (5.99) was recorded in the second season of 2012. The variations in the diversity, species richness and evenness between two cropping systems are discussed in this paper.
