“…Scientists do not agree on the role of S. mangiferae in causing yield loss and its impact on direct quality of mango fruit (Follett and Gabbard 2000;Follett 2002;Verghese et al 2005a), even though the occasional insect in fruit pulp can be unsightly. Until research provides evidence that can cause quarantine legislators to change their view of the weevil, S. mangiferae will remain a quarantine pest, and movement of mango fruits from areas with a history of presence of the weevil to many international destinations will have to meet quarantine regulations.…”

“…This process is both time-consuming and labour-intensive (Thomas et al 1995) and is thus expensive. A further cause of yield reduction by the weevil is premature fruit drop (Follett 2002;Verghese et al 2005a). The weevil also reduces per cent germination of seeds and thus the availability of seed as a source of rootstocks for propagation, although research has shown that seed germination rates for polyembryonic varieties are unaffected by weevil infestation (Follett and Gabbard 2000;Follett 2002).…”

Commercial mango production in Ghana is a relatively young industry faced with several pest problems including the mango stone weevil, Sternochetus mangiferae (F.). There is an urgent need to control this and other pests to facilitate access to the international export market for fresh mango fruits. A literature survey identifies stone weevil control tactics in the areas of host plant resistance, administrative and legislative controls, use of pesticides, biological control, cultural control and quarantine and phytosanitary measures that have been developed in other mango-producing areas. We assess these pest management approaches for their relevance to Ghana and West Africa, with emphasis on the research required for their appropriate, effective and sustainable use in the systems of mango production of the West African sub-region. The importance of processing and value addition technologies, as a means of circumventing the quarantine hurdles of S. mangiferae, is highlighted.

The European Commission requested EFSA to conduct a pest categorisation of Sternochetus mangiferae (Coleoptera: Curculionidae), a monophagous pest weevil whose larvae exclusively feed on mango seeds, whereas adults feed on mango foliage. S. mangiferae is a species with reliable methods available for identification. It is regulated in the EU by Council Directive 2000/29/EC where it is listed in Annex IIB as a harmful organism whose introduction into EU Protected Zones (PZ) (Alentejo, Algarve and Madeira in Portugal, and Granada and Malaga in Spain) is banned. S. mangiferae is native to South East Asia and has spread to other mango‐growing areas in Africa, South America and Oceania, causing significant damage. Larvae of S. mangiferae have been detected several times in mango fruit imported into the EU. In 2013, an outbreak was declared in one PZ in Spain. Official measures taken achieved eradication, which was officially declared in January 2018. The EFSA Plant Health Panel concludes that S. mangiferae could establish again and spread in the mango‐growing areas of southern EU. Considering the criteria within the remit of EFSA to assess the status as a potential Union quarantine pest (QP), as a potential protected zone quarantine pest (PZQP) or as a potential regulated non‐quarantine pest (RNQP), S. mangiferae meets with no uncertainties the criteria for consideration as a potential Union QP, as it is absent from the EU, potential pathways for entry exist, and its establishment would cause an economic impact. The criterion of the pest being present in the EU, which is a prerequisite for RNQP and PZ QP, is not met.

“…Thus, it is regarded as a quarantine pest of mango. Recent work has shown that S. mangiferae infestation does not signiÞcantly reduce germination rates (Follett and Gabbard 2000), but indirect measures suggested that S. mangiferae can increase fruit drop during early fruit development (Follett 2002, Verghese et al 2005a). Damage to the fruit pulp mainly occurs when adults emerge in late maturing varieties (Kok 1979).…”

Sternochetus mangiferae (F.) (Coleoptera: Curculionidae) is a quarantine pest of mango, Mangifera indica L., in South Africa. The aim of the study was to test cultural and chemical control measures in a systems approach for risk mitigation of S. mangiferae in South Africa. A large-scale experiment, using a randomized block design with three replicates, was undertaken on 'Tommy Atkins' mangoes in South Africa. Five treatment combinations were applied over two seasons: (1) untreated control; (2) sanitation and physical removal of egg-infested fruit (P+S); (3) thiamethoxam, P+S; (4) thiamethoxam, fipronil, P+S; and 5) thiamethoxam, two fenthion applications, P+S. A weekly random sample of eight fruit from 40 trees per orchard was taken from 5 wk to harvest over two harvest periods. In total, 57,600 fruit were sampled. In a separate experiment, the same variety was used to test the efficacy of covering fruit with paper bags over one season in a completely randomized design. In both trials, all the pests were recorded from internal and external fruit inspections. In trial 1, results after the first season showed >98% control in the three chemical combination treatments. In the second season, treatment 2 provided 19% and treatment 3 99.9% control, whereas no fruit were infested with S. mangiferae in treatments 4 and 5. Trial two showed that fruit bagging significantly reduced S. mangiferae infestation. The data showed that a systems approach for S. mangiferae control in South Africa can be effective and that bagging can be an effective organic control option.
