“…Insect samples were collected from traps every two weeks. The choice of this frequency was made to record population densities of a minimum of one generation, as the mean generation time is approximately 31 days and 48 days for B. dorsalis [ 50 ] and T. leucotreta [ 51 ], respectively. Insects from the Lynfield trap were preserved in 70% ethanol.…”

Avocado (Persea americana Mill.) production contributes to the economic growth of East Africa. However, poor fruit quality caused by infestations of tephritid fruit flies (Tephritidae) and the false codling moth, Thaumatotibia leucotreta (Meyrick), hampers access to lucrative export markets. Remote sensing and spatial analysis are increasingly applied to crop pest studies to develop sustainable and cost-effective control strategies. In this study, we assessed pest abundance in Muranga, Kenya, across three vegetation productivity classes, viz., low, medium and high, which were estimated using the normalised difference vegetation index at a landscape scale. Population densities of the oriental fruit fly, Bactrocera dorsalis (Hendel) and T. leucotreta in avocado farms were estimated through specific baited traps and fruit rearing. The population density of T. leucotreta varied across the vegetation productivity classes throughout the study period, although not significantly. Meanwhile, B. dorsalis showed a clear trend of decrease over time and was significantly lower in high vegetation productivity class compared to low and medium classes. Ceratitis cosyra (Walker) was the most abundant pest reared from fruit with few associated parasitoids, Pachycrepoideus vindemmiae (Rondani) and Toxeumorpha nigricola (Ferriere).

“…Though the FCM is polyphagous, host susceptibility varies among plant species, varieties of the same species and may depend on host plant characteristics (Djieto-lordon et al ., 2014; Moore et al ., 2017; Mkiga et al ., 2019). For instance, in South Africa, FCM infestation level varies among citrus varieties.…”

“…Lemons are not known to be infested at all, Valencia cultivars have low susceptibility, mid-season cultivars have moderate susceptibility while Navel oranges are very susceptible (Grout and Moore, 2015; Moore et al ., 2015). Sweet pepper is more preferred for oviposition than chilli pepper and African eggplant (Mkiga et al ., 2019). The preference of the FCM for host species may also vary with climatic conditions (Newton, 1990; Love et al ., 2014).…”

“…Eggs are randomly laid singly or in batches by the female during the night flight (between 5 and 11pm) in the depression of the rind of the fruit, on foliage, on smooth surfaces, on fallen fruits and occasionally on branches (USDA, 1984; Stibick et al ., 2010). At the optimum temperature of 25°C, the female lays between 3 and 8 eggs per fruit and can lay up to 800 eggs during its lifetime with the highest daily record after 3–4 days of oviposition period depending on the host species or the diet (Newton, 1998, De Jager, 2013; Mkiga et al ., 2019). Eggs take 2–22 days to hatch, depending on the temperature and humidity.…”

The false codling moth (FCM), Thaumatotibia leucotreta (Lepidoptera: Tortricidae) is an insect pest which represents an important threat to the production and marketing of a wide range of agricultural crops in the African-Caribbean-Pacific (ACP) countries. The FCM reduces not only the yield and quality of the crop but also as a quarantine insect pest, restricts the trade of susceptible agricultural produce on the international market. In addition, little research has been conducted in the ACP countries on the bio-ecology and sustainable management of this pest, especially on vegetables for export. Thus, action-oriented research aimed at understanding the bio-ecology of this important pest is essential to achieve effective management. Various management interventions against this pest have been used in some parts of the world, especially in South Africa on citrus. Currently, farm sanitation is regarded as the key management strategy. Exploring and improving on other interventions such as Sterile Insect Technique, monitoring and mass trapping of male moths, augmentative biological control, use of bio-pesticides, protected cultivation and cold treatment may help to mitigate the expansion of FCM into other countries, especially in the European and Mediterranean Plant Protection Organization region where it has become a regulated insect pest since 2014. This review discussed the bio-ecology of FCM and highlighted some of the challenges and opportunities for its effective management and its implication for international trade, especially the export of chillies from the ACP countries into the European Union market which requires strict phytosanitary regulations.

“…The species is currently known from 105 genera of plants in 51 families encompassing more than 130 different taxa (valid and unidentified species, hybrids, subspecies) (compilation from Couilloud, 1988;Venette et al, 2003; Although most demographic parameters (i.e. intrinsic rate of increase, doubling time) are comparable once host plants are infested (Mkiga et al, 2019), host fruit -like orange, aubergine, chilli and sweet pepper, okra -can differ greatly in oviposition preference, larval survival and larval incidence. Some taxa, such as lemon (Citrus limon) have been shown to be less vulnerable to attacks by T. leucotreta (Moore et al, 2015).…”

This pest survey card was prepared in the context of the EFSA mandate on plant pest surveillance (M‐2017‐0137) at the request of the European Commission. Its purpose is to guide the Member States in preparing data and information for Thaumatotibialeucotreta surveys. These are required to design statistically sound and risk‐based pest surveys, in line with current international standards.Thaumatotibialeucotreta is a clearly defined taxonomic entity,currently absent from the EU and surveys would thus be aimed at substantiating pest freedom. In the EU, T. leucotretais expected to be able to become established outdoors in the southernmost parts and indoors in other areas where susceptiblecrops are grown in greenhouses only if there is a year‐round availability of fruit. The most likely introduction of T.leucotreta would be via transport of infested fruit or cut flowers. Imports of fruit of the major host plants iscurrently subject to specific measures aiming to prevent entry of the pest into the EU.Thaumatotibialeucotreta is a moderate disperser; the maximum annual spread distance is estimated to be approximately 1.5 km. Thaumatotibialeucotreta is a highly polyphagous species and a large number of hosts are cultivated in the EU. The recommended hosts for detection surveys in the EU would be the main hosts that are grown on a large scale (e.g. Capsicum spp., Citrus spp. and Prunus spp.). Surveys should be based on a trapping strategy and target the adult moths. Both morphological and molecular methods are available for the identification of the pest.
