Brown marmorated stink bug (Halyomorpha halys) feeding damage determines early drop in olive crops

Abstract

The brown marmorated stink bug (BMSB), Halyomorpha halys Stål (Hemiptera: Pentatomidae), is an invasive species, nowadays worldwide listed among the key agricultural pests. Native of China, Japan and Korea, BMSB is a very polyphagous stink bug with an increasing list of recorded host plants (Hamilton et al., 2018). When it becomes established, it represents a major threat for several commercial crops such as apple (Bergh et al., 2019), hazelnuts (Hedstrom et al., 2014), kiwi (Chen et al., 2020, pears and peaches (Nielsen & Hamilton, 2009).Brown marmorated stink bug was first recorded in Italy in 2012, and since then it rapidly spread reaching high densities in the north of the country (Maistrello et al., 2018;Malek et al., 2019). In this area, olive trees (Olea europaea L.) produce modest quantities of high-quality extra virgin olive oil for both local market and export.Previous observations suggested that the damage of BMSB feeding activity on olive can be severe (D'Ascenzo et al., 2020;Damos et al., 2019) and that it may be associated with early drop (Minuto, 2021). Thus, the objective of this study was to examine the effect of BMSB feeding activity on developing olives by assessing

Effect of Halyomorpha halys Infestation on the Physicochemical Composition and Sensory Characteristics of Olive Fruits and Olive Oils

“…In conclusion, our findings revealed that, in addition to the damage caused to olive grooves by the insect's trophic activity resulting in the early olive drop, 8 the development of drupes on the trees and some quality parameters of the oils extracted from infested olives may be affected from bag's feeding activities. We observed a reduction in fruit size, with a proportional decrease in pulp and oil and the lipolytic modifications and loss of tissue structural integrity, in the face of a different insect attack on the drupes of the two cultivars (Dritta 49.5% Leccino 40.9%) and a different ripening index of the same.…”

“…It has recently been demonstrated that H. halys can infest olive trees, causing considerable damage to the plants and the early dropping of drupes due to the trophic activity of young individuals (nymphs) and adults. 8 The stinging and sucking apparatus of the insect is responsible for this damage to the drupes as it pierces the cuticle and reaches the deeper tissues in the vegetative phase before the drupes isolate themselves from the stone. When the endocarp is completely lignified, the fruit no longer falls off.…”

“…2 These introductions shared a few common steps: multiple arrivals probably associated with commercial trading; 3 population expansion often associated with urban areas; 4,5 and finally extensive crop damage, with a worrisome growing list of host plants. 6 In the invaded areas, H. halys reached high levels of population density and caused significant economic losses to farmers. [7][8][9] Integrated pest management (IPM) strategies for the management of H. halys, such as mass trapping, trap crops, 10 perimeter restructuring in apple orchards, [11][12][13] push-pull, 14 exclusion nets 15 and behavioral manipulation 16 alone had only reduced potential to significantly decrease the damage to fruits.…”

“…Halyomorpha halys was first recorded in the United States in the mid‐1990s and in Europe almost 10 years later 2 . These introductions shared a few common steps: multiple arrivals probably associated with commercial trading; 3 population expansion often associated with urban areas; 4,5 and finally extensive crop damage, with a worrisome growing list of host plants 6 . In the invaded areas, H. halys reached high levels of population density and caused significant economic losses to farmers 7–9 …”

First evidence of the brown marmorated stink bug and its population size in perennial crops in Croatia

“…A short time later, this pest was also detected in Slovenia (Rot et al, 2018) and Bosnia and Herzegovina (Zovko et al, 2019) This pest is considered a serious urban and household pest because it easily enters households to overwinter (Lee et al, 2013;Leskey and Nielsen, 2018). However, numerous cases of economic damage to agricultural production have been reported (Bariselli et al, 2016;Candian et al, 2018;Gariepy et al, 2015;Lee, 2015;Schumm, 2020;Vétek and Korányi, 2017;Zapponi et al, 2022). Early infestation with H. halys can lead to economically significant yield losses (Schumm, 2020).…”
