“…2 For example, the soybean leaf miner, Aproaerema modicella (Deventer) that was introduced into South Africa and reported as a pest of groundnut during the early 2000s also attacks soybean in certain areas of the country. 5 A similar scenario was experienced in 2001 when the economically important soybean rust disease, caused by the newly-introduced fungus Phakopsora pachyrhizi Sydow, was first recorded as a major pathogen of soybean crops in traditional local production areas. 6 Not only should soybean cultivars be adapted to local environmental conditions to optimise crop performance, it should also exhibit resistance to diseases and pests such as plant-parasitic nematodes, bacteria, fungi and insect pests.…”

DeceasedThe area planted to soybean in South Africa has increased by 54% since the 2009 growing season, mainly as a result of the increasing demand for protein-rich food and fodder sources. Moreover, the introduction of advanced technology, namely the availability of genetically modified herbicide tolerant soybean cultivars also contributed towards increased soybean production. The omnipresence of plant-parasitic nematodes in local agricultural soils, however, poses a threat to the sustainable expansion and production of soybean and other rotation crops. Meloidogyne incognita and M. javanica are the predominant nematode pests in local soybean production areas and those where other grain-, legume-and/or vegetable crops are grown. The lack of registered nematicides for soybean locally, crop production systems that are conducive to nematode pest build-ups as well as the limited availability of genetic host plant resistance to root-knot nematode pests, complicate their management. Research aimed at various aspects related to soybean-nematode research, namely, audits of nematode assemblages associated with the crop, identification of genetic host plant resistance in soybean germplasm to M. incognita and M. javanica, the use of molecular markers that are linked to such genetic resistance traits as well as agronomic performance of pre-released cultivars that can be valuable to producers and the industry are accentuated in this review. Evaluation of syntheticallyderived as well as biological-control agents are also discussed as complementary management tactics. It is important that lessons learned through extensive research on soybean-nematode interactions in South Africa be shared with researchers and industries in other countries as they might experience or expect similar problems and/or challenges.

“…The high GLM severity scores (>60% leaf damage) in unprotected plots is evidence that GLM can cause serious damage to soybean if left uncontrolled (Table 7). This damage caused in photosynthetic tissue reduces the surface area for light interception decreasing crop growth rate, photosynthetic partitioning and ultimately results in yield loss (Du Plessis, 2003;Kenis and Cugala, 2006) especially as it happens early in the growth cycle (14 DAP).…”

Groundnut leaf miner (GLM) is currently a threat to soybean production in Uganda due to the great yield losses as a result of the severe damage it causes on leaves leading to reduced photosynthetic area. GLM is a fairly new pest on soybean in Uganda, having initially been observed in soybean fields in 2011 in eastern Uganda. The objective of this study was to determine the yield loss caused by the groundnut leaf miner and effectiveness and profitability of commonly used pesticides for the control of the groundnut leaf miner (Aproaerema modicella Deventer) (GLM), when tested with popular soybean (Glycine max) genotypes grown in Uganda. In a split plot RCBD design, pesticide protection (treated vs. untreated) formed the main plots; and six commercial soybean varieties (Maksoy 1N, 2N, 3N, 4N, 5N; and Namsoy 4M) as subplots. The study was done in two locations in eastern Uganda (Iki Iki District Agricultural Training and Information Centre (Iki Iki DATIC) and National Semi-Arid Resources Research Institute, Serere (NaSARRI) with two planting rounds at Iki Iki. These sites were chosen because they are hot spots for GLM. GLM severity and soybean yield were significantly affected by the pesticide protection. Overall, percentage grain yield losses caused by GLM on the different soybean varieties ranged from 37.3% to 65.7% and the highest loss was displayed by Maksoy 5N. Grain yield loss recorded at Iki Iki DATIC (53.1%) was remarkably higher than that recorded at the NaSARRI (49.1%). Economic analysis showed marginal returns to be dependent on location, with the Iki Iki DATIC having 0.6 and NaSARRI 1.1. This study has shown that the groundnut leaf miner, a recently emergent pest of soybean is becoming a big threat to soybean production and that chemical control alone may not be economical in managing the pest.

“…During 2001 it was found causing damage to groundnut crops over the entire groundnut production area in the Free State, Northern Cape, North-West and Mpumalanga provinces. A. modicella was also observed on soybean in Mpumalanga and lucern in the Northern Cape province in 2001 (Du Plessis, 2003).…”

“…The groundnut leafminer (GLM), Aproaerema modicella (Deventer) (Lepidoptera: Gelechiidae) was reported in East Africa during 1998 after which it rapidly spread throughout East and southern Africa (Du Plessis, 2003). During 2000 GLM was also reported in South Africa, first at the Vaalharts Irrigation scheme (27º50'S;24º50'E) in the Northern Cape Province.…”

“…Larval tunnelling into leaves and feeding between the upper and lower epidermis results in formation of mines in the leaf. The final-instar larva spins a web between two or more leaflets thereby creating an enclosure in which pupation takes place (Du Plessis, 2003). High larval infestation levels result in large scale defoliation which may affect growth and yield of plants (Kenis & Cugala, 2006).…”
