“…Coccus viridis and C. hesperidum previously have been recorded as serious citrus pests in Kenya (Kilalo, 2004, Olubayo et al, 2011, Gitahi, 2018. Soft scales, often being polyphagous, have been reported to be serious pests of other crops worldwide such as grape, mango and papaya (Kapranas et al, 2007;Walton et al, 2009;Martins et al, 2014).…”

“…The male undergoes two feeding nymphal instars before molting to a non-feeding pre-pupa, then a non-feeding pupa, and finally to the winged adult male (Kondo et al, 2008). Scale insect are sap-feeding insects that impair many plants, and diminish yield and marketable value of attacked plants (Martins et al, 2014). On citrus trees, scale insects inflict direct damage by extracting plant sap containing water and nutrients, reducing host-plant vigor and causing wilting, which stops photosynthesis.…”

“…The sooty mould blocks light and air from reaching the leaves, impeding photosynthesis and causing plant productivity to decrease. The presence of sticky honeydew and black sooty mould lowers the market value of plant produce and ornamental plants (Muniappan et al, 2009;Martins et al, 2014).…”

Citrus farming is a major source of revenue for large and small-scale farmers in Kenya. Citrus production is confronted with threats from pests and diseases. Surveys of citrus farms in Kilifi, Kwale, Machakos and Makueni counties, Kenya in July/August (dry season) and in November/December (wet season), 2019 were conducted to identify scale insect pests (Hemiptera: Coccomorpha) attacking the trees (Sapindales: Rutaceae), and their related biota. A total of 22 scale insect species belonging to four families, namely Diaspididae (armoured scales), Coccidae (soft scales), Pseudococcidae (mealybugs), and Monophlebidae (giant mealybugs) were found infesting citrus trees in the two regions surveyed. Among the scale insects reported, four species were newly introduced in Kenya; three armoured scales Parlatoria ziziphi (Lucas), Parlatoria pergandii (Comstock), Aonidiella comperei (McKenzie), and a soft scale, Pulvinaria polygonata (Cockerell). The scale insects were closely associated with predators (coccinellids and lacewings) and attendant ants. This information will be helpful in the development of efficient management strategies against the scale insect pests, thus improving citrus production in Kenya. The scale insect pests identified in this study will be useful to plant quarantine facilities in Kenya to help to prevent and detect accidental introductions of exotic scale insect species.

“…It also killed a number of papaya trees in Bermuda . In the past, M. longispina has also been recorded as papaya pest in Brazil but without confirmation in the last few years (Martins et al, 2014). Other damage reports refer to fig in Algeria, Bermuda, Florida and to Bauhinia and Jasminum in New Caledonia .…”

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by 2‐year‐old bare rooted plants for planting of Acer palmatum grafted on rootstocks of Acer davidii imported from China to the EU, taking into account the available scientific information, including the technical information provided by China. All pests associated with the commodity were evaluated against specific criteria for their relevance for this Scientific Opinion. Twenty‐two pests that fulfilled all relevant criteria were selected for further evaluation. For 20 pests, the risk mitigation measures described in the technical dossier from China were evaluated taking into account the possible limiting factors. For these pests, an expert judgement is given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. While the estimated degree of pest freedom varied among pests, Lopholeucaspis japonica was the pest most frequently expected on the commodity. The Expert Knowledge Elicitation indicated, with 95% certainty, that 9,336 or more bare rooted plants per 10,000 will be free from L. japonica . For Anoplophora chinensis and Anoplophora glabripennis , the Panel considers that China applies the relevant measures as specified in Commission Implementing Decision (EU) 2012/138 and Commission Implementing Decision (EU) 2015/893.

“…Fifteen orchards were sampled in the municipalities of Linhares (19.3821667°S, 40.0286667°W), 3 in Sooretama (19.0716667°S, 40.1477778°W), and 2 in Aracruz (19.7679722°S, 40.1763333°W) ( Fig. 1), northern Espírito Santo State, the main Brazilian papaya-producing and -exporting region (Martins et al 2014). Thrips specimens were collected with Moericke traps made of yellow plastic trays (30 cm diameter and 5 cm height) filled with a mix of water and a few detergent drops.…”
