Penicillium Rubrum

The fungal counts per gram of air-dried dates, of eight local date-palm varieties, varied markedly on different synthetic media. Seri and Shakra varieties had highest fungal counts whereas Medina had the lowest. Aspergilus flavus, A. niger, Penicillium rubrum, P. oxalicum, Rhizopus stolonifer, Stemphylium verruculosum and Fusarium sp. were generally associated with various date varieties. Apparent colonization of the fungi was obtained by increasing the relative humidity to 90% at 30 and 40°C. Best growth of the isolated fungi in artificial media was obtained at 60% glucose concentration.

Comprehensive Survey

A comprehensive survey was conducted at different provinces of Saudi Arabia (SA) to investigate predacious prostigmatid mites (Acari: Trombidiformes: Prostigmata) mainly collected from the date palm, Phoenix dactylifera L. (Arecaceae) agro-ecosystem. A total of 41 species belonging to 28 genera in 14 families are recorded in the present study. Out of these, three families, 18 genera and 36 species are new to the mite fauna of SA. The new species, Neobonzia tabukensis sp.nov. (Cunaxidae), Cheletomimus (Philippicheyla) taifensis sp.nov. (Cheyletidae) are described and illustrated. A checklist of predatory prostigmatid mites from SA is given. A key to all terrestrial predatory prostigmatid mites, excluding Parasitegona and Heterostigmatina, reported from SA is provided. Also, a key to world species of the subgenus Philippicheyla Corpuz-Raros of the genus Cheletomimus Oudemans is given.

Collection Data

This paper reports on 35 species and 33 genera belonging to 18 families of the order Mesostigmata, collected from different provinces of Saudi Arabia. Among these, eight families, 21 genera and 30 species, mostly collected from date palm agroecosystem, are new to the fauna of Saudi Arabia. Five species reported previously are also recorded in this study. The collection data and distribution of all species recorded in this study as well as those reported previously are given. A comprehensive key to the females of the mesostigmatic mites reported from Saudi Arabia, except the Phytoseioidea, is provided.

This study was aimed to investigate weeds kind in palm plantations. Date palm is the most chief economic crop in most countries of the Arabian Peninsula. Many factors, such as the presence of weeds, may cause a huge loss in the production of dates. Despite the severe damage caused by the presence of some weeds in agroecosystems, many weeds have many medicinal and economic uses. A total of 62 species were listed in palm Plantations in Tabuk and Al-Qassim Regions. A total of 51 species were listed in Tabuk Region (The number of unique species in the Tabuk Region reached 32 that not recorded in Al-Qassim Region. Also, 19 species were recorded in both of Tabuk and Al-Qassim Regions). A total of 30 weeds were listed in Al-Qassim Region (The number of unique species in the Al-Qassim Region reached 11 that not recorded in the Tabuk Region. In addition to, 19 species were recorded in both of Tabuk and Al-Qassim Regions). Zygophyllaceae was the most common family, the majority life span was annuals and the most common life form was therophyte in both Tabuk and Al-Qassim Regions. Data management and classification were achieved using PCORD (TWINSPAN and DCA analyses).
