AbstractThe invasive stink bug Halyomorpha halys Stål (Hemiptera: Pentatomidae) has recently become established in Canada, but little information is available regarding the ability of natural enemies to attack this pest in its invaded range. We tested the capacity of several life stages of three generalist predators, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), Coleomegilla maculata De Geer (Coleoptera: Coccinellidae), and Podisus maculiventris (Say) (Hemiptera: Pentatomidae), to attack H. halys eggs. The relative susceptibility of H. halys eggs to predator attack was compared to P. maculiventris eggs. We found evidence for differential ability to consume H. halys and P. maculiventris eggs both among predator species and within species among life stages. The most H. halys eggs were consumed by late-instar C. carnea, while fewest were consumed by second-instar and adult C. maculata, and second-instar C. carnea. The susceptibility of H. halys eggs to predators was similar to that of P. maculiventris eggs, with only early-instar P. maculiventris nymphs consuming significantly less H. halys eggs than P. maculiventris eggs. Our results provide a baseline for further testing of generalist predators against H. halys and illustrate the potential importance of considering the breadth of ontogeny across which candidates are able to attack the invasive pest.

Halyomorpha halys is an important invasive pest that causes severe damage to fruits and vegetables. Peppers are susceptible to infestation by H. halys, resulting in yield losses. Plants respond to the insect infestation with a metabolic response. With this study, we attempted to determine the intensity of the metabolic response of infested peppers, how pungent and non-pungent peppers react to the infestation, and how the H. halys affects the post-harvest quality of both cultivars. The shelf life of the infested peppers did not change compared to the control treatments. We observed a drastic decrease in metabolite levels after storage in all three treatments in both cultivars, especially capsaicinoids, with an approximate decrease of 30% in the pericarp and 95% in the placenta of the pungent ‘Eris F1’. In some cases, the accumulation of metabolites was not limited to the fruit exposed to the H. halys infestation, but to the entire plant. We observed a 15-fold increase in capsaicinoid content in the infested fruits of cultivar ‘Eris F1’ and a 4-fold increase in the pericarp of cultivar ‘Lombardo tago’, which could lead to a possible further study on the defensive function of capsaicinoids and their use against H. halys.

Halyomorpha halys (Hemiptera: Pentatomidae), native to East Asia, has become a globally invasive pest, as a serious threat to agricultural production and a notorious nuisance pest in urban areas. Considerable efforts have been made so far to develop effective pest control measures to prevent crop damage. Biological control of this invasive stink bug by egg parasitoids has proven to be the most environmentally sustainable long-term solution. Knowledge of the native egg parasitoid fauna is of key importance when implementing a biological control program. Therefore, the main objective of our study was to detect egg parasitoid species associated with H. halys in the Goriška region (Western Slovenia) and to evaluate their impact on the pest population under field conditions. In the years 2019 and 2020, around 4600 H. halys eggs were collected in the wild and more than 3400 sentinel eggs were exposed to detect parasitoids in the field. Five egg-parasitoid species emerged from H. halys eggs: Anastatus bifasciatus (Hymenoptera: Eupelmidae), Telenomus sp., Trissolcus basalis, Trissolcus mitsukurii (Hymenoptera: Scelionidae) and Ooencyrtus telenomicida (Hymenoptera: Encyrtidae), all of them are new records for Slovenia. The native species, An. bifasciatus, dominated in urban and suburban areas, while non-native Tr. mitsukurii prevailed in agricultural areas. Overall parasitism rates of naturally laid eggs by the parasitoid species complex in 2019 and 2020 was 3.0 and 14.4%, respectively. Rapid recruitment of native parasitoids, early detection of an effective alien parasitoid species and increasing overall parasitism rates are very encouraging results, which need to be followed and verified in future research.

Представлена информация о происхождении и географическом распространении коричнево-мраморного клопа Halyomorpha halys Stl (Hemiptera: Pentatomidae). Приведены данные об инвазивном ареале и вредоносности коричнево-мраморного клопа на юге России. Дано описание морфологических и биологических особенностей вредителя. Описаны методы мониторинга и борьбы с вредителем. Коричнево-мраморный клоп опасный инвазивный вредитель, происходящий из восточной Азии. Он повреждает значительное количество экономически значимых растений, включая различные овощные и плодовые культуры, а также лесные и декоративные растения. В Европе вредитель впервые был выявлен в 2004 году в Швейцарии и Лихтенштейне к 2020 году он распространился в 26 странах континента. На территории Евразийского экономического союза впервые зарегистрирован в России в 2014 году, на территории города Сочи в 2017 году впервые обнаружен в Казахстане. Сегодня происходит формирование инвазивного ареала вредителя на юге России: он распространился в Краснодарском крае и в республике Крым. Коричнево-мраморный клоп способен питаться на более чем 300 видах растений из 49 семейств, включая различные плодовые, овощные, декоративные и лесные растения. Из овощных культур наиболее сильно повреждает томаты, перец, баклажан, огурец, фасоль, горох и кукурузу, из плодовых культур яблоню, грушу, персик, черешню, цитрусовые, лещину, хурму и виноград. Уже в 2016-2017 годах H. halys нанес серьезный вред овощным и плодовым культурам в Краснодарском крае. Выявление очагов коричнево-мраморного клопа осуществляют методами визуального и феромонного мониторинга. Феромонный мониторинг позволяет выявлять вредителей даже при низкой численности, его осуществляют при помощи феромонных ловушек, которые размещают с мая по сентябрь. В Государственный каталог пестицидов и агрохимикатов, разрешенных к применению на территории Российской Федерации включено три инсектицида против этого вредителя, но препараты, разрешенные для защиты от него пасленовых и бобовых культур, сегодня в нем отсутствуют.The article provides information on origin and world distribution of the brown marmorated stink bug, Halyomorpha halys Stl (Hemiptera: Pentatomidae). The data on the invasive range and harmfulness of the pest in the South of Russia is presented. The description of morphological and biological features of the pest is given. The pest monitoring and control measures are described. The brown marmorated stink bug is a dangerous invasive pest of East Asia origin. It damages a number of economically important plants, including various vegetable and fruit crops, as well as forestry and ornamentals. In Europe, this pest has been recorded for the first time in 2004, in Switzerland and Liechtenstein as of 2020, it has been introduced to 26 countries of the continent. In the Eurasian Economic Union, the pest has been recorded for the first time in Russia in 2014, in the territory of Sochi in 2017 it has been recorded for the first time in Kazakhstan. The invasive range of the pest is currently being formed in the South of Russia. The pest has spread to the Krasnodar Krai and the Republic of Crimea. The brown marmorated stink bug feeds on more than 300 plant species from 49 families. The most severely damaged vegetable crops are tomatoes, peppers, aubergine, cucumber, beans, peas and corn among the fruit crops, the highest damage occurs in apples, pears, peaches, cherries, citrus fruit crops, hazel, persimmons, and grapes. As early as in 2016-2017, the brown marmorated stink bug caused serious damage to vegetable and fruit crops in the Krasnodar Krai. Detection of outbreaks of the brown marmorated stink bug is carried out by both visual and pheromone monitoring. Pheromone monitoring allows identifying pests even at low population densities it is carried out using pheromone traps, which are placed on the edges of fields from May to September. The State catalogue of pesticides and agrochemicals permitted for use on the territory of the Russian Federation includes 3 insecticides recommended for use against this pest, but so far there are no preparations permitted for protection of solanaceous and legume crops.

The Impact

Outbreaks of the Nearctic leafhopper Erasmoneura vulnerata represent a threat to vinegrowers in Southern Europe, in particular in North-eastern Italy. The pest outbreaks are frequent in organic vineyards because insecticides labeled for organic viticulture show limited effectiveness towards leafhoppers. On the other hand, the naturally occurring predators and parasitoids of E. vulnerata in vineyards are often not able to keep leafhopper densities at acceptable levels for vine-growers. In this study, we evaluated the potential of two generalist, commercially available predators, Chrysoperla carnea and Orius majusculus, in suppressing E. vulnerata. Laboratory and semi-field experiments were carried out to evaluate both species’ predation capacity on E. vulnerata nymphs. The experiments were conducted on grapevine leaves inside Petri dishes (laboratory) and on potted and caged grapevines (semi-field); in both experiments, the leaves or potted plants were infested with E. vulnerata nymphs prior to predator releases. Both predator species exhibited a remarkable voracity and significantly reduced leafhopper densities in laboratory and semi-field experiments. Therefore, field studies were carried out over two growing seasons in two vineyards. We released 4 O. majusculus adults and 30 C. carnea larvae per m2 of canopy. Predator releases in vineyards reduced leafhopper densities by about 30% compared to the control plots. Results obtained in this study showed that the two predators have a potential to suppress the pest density, but more research is required to define appropriate predator–prey release ratios and release timing. Studies on intraguild interactions and competition with naturally occurring predators are also suggested.
