South African National Survey of Arachnida Photo Identification Guide: The Palpimanidae of South Africa

The African genera have not been updated. Presently ten of the species are South African endemics, with five others being identified from Southern Africa. With 882 Palpimanidae records in the National Collection of Arachnida with Diaphorocellus and Palpimanus, 747 records have been found, but 73% of the accesions have not been identified to species level, although 73% have not been identified to species level.

A reassessment of public awareness and legislative framework on cybersecurity in South Africa

In recent years, massive data leakage has resulted in massive data breaches, and analysis has suggested that artificial intelligence can be used to create more robust cyber-attacks, revealing new hardware flaws. By the same token, there are reports that the South African Banking Risk Information Center loses more than R2. 2 billion per year to cyber-attacks each year. The report finds that with increasing legislation focusing on cybersecurity, increasing legislative attention on cybersecurity, the research shows that in addition, there is also the need for numerous academic and academic institutions to provide hands-on education to the community by research-based initiatives to ensure South Africa is resilient to the country's increasing challenges. Given the borderless nature of cybercrime, South Africa should continue to integrate the Joint Cybercrime Taskforce into local legislation and necessitate the establishment of law-oriented learning centers, where citizens can be advised of the dangers of cybercrime and its disastrous effects on national development.

Illicit use of Drugs among the Youth and Adults in the Frances Baard Region: Northern Cape, South Africa

Both for the individual and for society, the use of illicit drugs by adolescents and young adults has significant negative consequences both for the individual and society. In the Frances Baard District Municipality, Northern Cape Province, South Africa, this essay explores the prevalence, causes, and practices of illicit drug use by youth and adults. It is known that illicit drug use among the youth and adults often occurs as a result of a lack of support; it is also understood that illicit drug use among the youth and adults is high;freedom’;freedom’;freedom’; To discourage the spread of opioid use among youth and adults, steps must be implemented. Therefore, it is critical to ensure the proper implementation of support services, including legislation and court action, to tackle drug use among youth and adults in the Frances Baard District Municipality, Northern Cape's youth and adults.

South African National Survey of Arachnida Photo Identification Guide: Oecobiidae of South Africa

The Oecobiidae is a small family of spiders found in six genera and 119 species. Both Oecobius species are native to the United States and have a large worldwide distribution. Paroecobius is a genus Paroecobius that was identified by Lamoral and is an African endemic. In South Africa, three species of Uroctea are present. 1910 is a South African endemic, while the other two are southern Africa endemics. Uroecobius is monotypic and identified only from Uroecobius ecribellatu s Kullmann & Zimmermann, 1976, a species with a wide distribution in South Africa endemic to South Africa, with a wide distribution restricted to South Africa. Uroecobius is a monotypic and distinct species unique to Uroecobius.

Genetic diversity of 'Candidatus Liberibacter africanus' in South Africa based on microsatellite markers

Citrus Greening disease in South Africa is caused by the fastidious bacteria u2018 Candidatus Liberibacter africanus u2019. During transplantation experiments, Laf isolates obtained from various geographical locations in SA differed in the rate of transmission, leading to the conclusion that genetic variation of Laf exists in this region. According to additional information, Laf populations in SA are influenced by geographic location. The high genetic diversity observed for Laf in this study is consistent with the assumption that Laf ancestorate on the African continent, triggering further genetic analysis of Laf populations from Africa.

Host range testing of Tamarixia dryi (Hymenoptera: Eulophidae) sourced from South Africa for classical biological control of Trioza erytreae (Hemiptera: Psyllidae) in Europe

Trioza erytreae, an African citrus psyllid, is a vector that causes citrus greening or huanglong disease. We reviewed the host specificity of T. dryi using 11 non-target psyllid species, including five species of the genus Trioza. A high host specificity was present in Tamarixia driedi. Females did not parasitize any of the 11 NTPs tested, except for one nymph of a gall-forming Trioza species closely related to Trioza montanetana. On Convolvulus canariensis' gall and exposed directly to the parasitoid, Tamarixia dryi only laid one egg on a nymph when it was removed from the gall and revealed immediately to the parasitoid. After long time exposure, we learned that T. dryi did not parasitize Trioza laurisilvae of the endemic Canarian fauna, not parasitize a representative triozid species of the endemic Canarian fauna. Our findings show that T. dryi is a very specific parasitoid, with its introduction, propagation, and establishment in Europe within T. erytreae's classical biological surveillance program, and it should not affect other psyllid species.

Potential insect vectors and alternative host plants of phytoplasmas inthe Fynbos and Succulent Karoo biomes in South Africa

In the Fynbos and Succulent Karoo biomes in South Africa, potential insect vectors and alternative host plants of grapevine yellows were tested. The results will be used to establish the insect vector status and the role of the plant species identified as alternative host plants in controlled transmission experiments.

South African National Survey of Arachnida Photo Identification Guide: The Cyrtaucheniidae of South Africa

Only the genus Ancylotrypa Simon, 1889, is recognized by 29 species in South Africa. During the South African National Survey of Arachnida, the genus was abundantly collected, but only 41% of these entries were identified to species level, with a total of 635 entries in the National Collection of Arachnida.
