AbstractSince Maconellicoccus hirsutus (Green), a pest of many plants including Hibiscus, was introduced into Egypt in 1908, probably from the Oriental Region, it has spread to much of tropical Africa. There is little information available on its control, but the encyrtid Anagyrus kamali Moursi is known to give good control in Egypt. The ladybird Cryptolaemus montrouzieri Mulsant is a voracious feeder on M. hirsutus in Egypt, but it does not survive the Egyptian winter, although it may be useful in the tropical areas. M. perforatus (De Lotto) is synonymized with M. hirsutus, and the distribution and host-plants of this species in Africa are discussed. A lectotype is designated for M. ugandae (Laing), a species now known to occur throughout tropical Africa, especially on coffee and cocoa. It is illustrated and redescribed and compared with M. hirsutus. M. bardus De Lotto, known from South Africa only, is excluded from the study because it probably belongs to the genus Chorizococcus.

Four species of Arthothelium from Africa and Socotra are described as new to science: Arthothelium atrorubrum from Madagascar, characterized by irregularly rounded blackish ascomata with a deeply red hypothecium and submuriform ascospores; Arthothelium aurantiacopruinosum from the Democratic Republic of the Congo, characterized by black, irregularly rounded to stellate, orange pruinose ascomata and muriform ascospores with two larger terminal cells; Arthothelium frischianum from Madagascar, characterized by brownish-black minute irregular ascomata with remnants of thallus and muriform ascospores with one larger terminal cell; Arthothelium miesii from Socotra (Yemen), characterized by a thick thallus, immersed, stellate to cerebriform, brownish, greyish pruinose ascomata and submuriform ascospores. A key to all reported species of Arthothelium from tropical Africa (South Africa excluded) and Socotra is provided.

Insect-vectored viruses are a major threat to grapevine production but there is a dearth of information on the occurrence and distribution of key grapevine pests in Nigeria. The recent detection of grapevine leafroll associated virus-1 (GLRaV-1), a known insect-vectored ampelovirus, in Nigeria elevates the importance of the identification of its potential vectors as a precursor to assessing the risk of grapevine leafroll disease spread. This study was conducted to determine the occurrence and diversity of potential vectors of grapevine viruses and their natural enemies in vineyards across the savannah agro-ecological region of Nigeria. Forty vineyard and nursery locations were surveyed during 2016 and 45 arthropod samples were collected. The samples were first morphologically identified, and DNA barcoding was conducted on a subset of 16 representative samples using universal primers specific to the Mitochondrial Cytochrome Oxidase subunit I (mtCOI) gene of most insects. The results indicated the presence of two species of scale insects (Parasaissetia nigra and Saissetia coffeae) and two mealybug species (Maconellicoccus hirsutus and Ferrisia virgata), some ofwhich are potential grapevine virus vectors, in Nigerian vineyards. In addition, the natural enemies of these insect species were detected which includes three species of parasitoids (Anagyrus kamali, Anagyrus pseudococci and Encarsia inaron) and one predator (Hyperaspidius mimus). While the detection of mealybugs and scale insects underscore the risk of vector-mediated virus spread in Nigerian vineyards, the identification of their natural enemies indicates presence of natural biological control agents to facilitate an integrated management of economically important grapevine virus diseases in the country. Keywords: Mealybugs; scale insects; parasitoids and predators; insect vectors; grapevine viruses.

Due to their intricate life histories and the unique wing patterns and colouring the butterflies of the genus Chrysoritis are of significant conservation and aesthetic value. Thisoverview probes into practical examples of butterfly life history research applicable to environmental management of this relatively well-known invertebrate group in South Africa. Despite the pioneer work on life histories of Chrysoritis in the past, more should be done to understand the life history of the butterflies in the wild, especially their natural host plants and the behaviour of adults and larvae. A system of voucher specimens of host plants should be introduced in South Africa. Although various host plant species in nature are used by the members of Chrysoritis, including the Chrysoritis chrysaor group, the choice of these in nature by each species is significant for conservation management and in the case of Chrysoritis aureus perhaps even as a specific characteristic.A revision of the ant genus Crematogaster will benefit the conservation management of Chrysoritis species since some of these ant species may consist of a number of specieswith much more restricted distributions than previously thought. Rigorous quantified tudies of population dynamics of Chrysoritis butterflies are absent and the introductionof such studies will benefit conservation management of these localised butterflies extensively.
