“…exist in South Africa, even though there are no reports, as yet, on its commercial use (Peris-Felipo and Belokobylskij 2016). Furthermore, the use of parasitoids from the Eulophidae family has been recorded against pupae of the groundnut leaf miner, Aproaerema modicella (Deventer) (Lepidoptera: Gelechiidae) ( Van der Walt et al 2009).…”

Occurrence of the potato leaf miner, Liriomyza huidobrensis (Diptera: Agromyzidae), and parasitoids in potato fields and natural vegetation of the Western Cape province, South Africa

The leaf miner, Liriomyza huidobrensis (Diptera: Agromyzidae) is a polyphagous fly, which infests a wide range of vegetables and ornamental plants. However, scant knowledge exists of the biology and ecology of the pest in the Western Cape province of South Africa, both of which are essential components in developing an effective management programme. Several aspects of its biology and ecology were studied in two potato [Solanum tuberosum L. (Solanales: Solanaceae)] fields in the Sandveld region during both winter and summer months. The population densities of adult L. huidobrensis were monitored using yellow sticky traps, which were retrieved and counted once every two weeks (June 2019 to January 2020). The number of leaf miner adults caught throughout the summer and winter monitoring periods was significantly different. In addition, 50 randomly selected plants were assessed for leaf damage (in the form of punctures and mines) using presence/absence sampling. Leaf miner persistence within the soil was confirmed through one-time soil sampling of the two fields, one month after harvesting. Leaf miner pupae were detected in the soil samples after the potatoes were harvested. However, no adult emergence was recorded among the collected pupae under laboratory conditions. The observed trend was that the traps, in both fields, caught an increasing number of leaf miners as the crops matured. Damage occurred in both the monitored fields as early as week four, after plant emergence. Of the five parasitoid species collected, Diglyphus isaea (Hymenoptera: Eulophidae) was the most abundant.

“…The present results may be explained by the relatively short CLM exposure time to local parasitoids, given that native leafminers are usually heavily parasitized (Hawkins, 1994; Eber, 2004) while alien ones may be instead more preyed than parasitized (e.g., Grabenweger et al , 2005; Xiao et al , 2007). However, some invasive leafminer pests have shown remarkably high parasitism levels (Van der Walt et al , 2009). It must be noticed that sampled orchards remained under conventional management, including applications of insecticides, as described in Materials and methods section.…”

Studies on insect natural enemies and their effects on host populations are of immense practical value in pest management. Predation and parasitism on a citrus pest, the leafminer Phyllocnistis citrella Stainton, were evaluated by sampling over 3 years in four locations within a world leading lemon producing area in Northwest Argentina. Both mortality factors showed seasonal trends consistent across locations, with predation exerting earlier and more sustained pressure than parasitism, which showed wider seasonal variations. The dominant parasitoids, native Cirrospilus neotropicus and introduced Ageniaspis citricola, showed different seasonal trends: C. neotropicus was dominant in spring whereas A. citricola superseded it in autumn and winter. Although parasitism rates were relatively low, the native C. neotropicus revealed favourable features as potential control agent, by showing density-dependence, parasitism rates comparable with those of the specific A. citricola during part of the cycle, and earlier synchronization with the host. The study provides highly relevant information for a sustainable management of this worldwide pest, for which biological control is considered the best long-term option.

“…In southern Mozambique, infestation levels that cause economic damage range from 29 to 38 larvae per plant (Kenis & Cugala 2006). In South Africa, the threshold has been set at between 2 and 10 larvae per plant (Van der Walt et al 2009). However, the critical plant growth stages at which these infestation levels reach the economic threshold levels have not been specified for Mozambique or South Africa.…”

Review of the biosystematics and bio‐ecology of the groundnut/soya bean leaf miner species (Lepidoptera: Gelechiidae)

Aproaerema modicella (Deventer), Aproaerema simplexella (Walker) and Stomopteryx subsecivella (Zeller, 1852) (Lepidoptera: Gelechiidae) are micro moth (Micro-Lepidoptera) pests of groundnut and soya bean that have been described as different species on different continents. Recent DNA analyses of these species suggest that they are conspecific. Here, a review with emphasis on the genetics, biology, ecology and known host plant preferences of this apparent species is given. We argue, through the genetic/DNA data and analyses, that the three species should be grouped as a single species. The review ends by highlighting the areas that need further research to confirm our hypothesis.
