“…The H. halys feeding damage on kiwifruit has been referred to in recent years [40][41][42][43][44][45], and may be a potential threat for A. deliciosa "Hayward" in Greece. The entomopathogenic effect of B. bassiana on invasive pests is a fact, not only found in this study, but also in other research [46][47][48].…”

In this study, the bioinsecticidal action of a commercial formulation with Beauveria bassiana was evaluated on the new sucking pest in Greece: Halyomorpha halys, of the kiwifruit. Additionally, the biostimulant potential of the same formulation was studied on kiwi growth. The application was performed in three different ways in a commercial field of kiwi crop A. deliciosa “Hayward” field in Arta, Greece: (i) trunk spray, (ii) root injection, and (iii) trunk inoculation. During the 2 years seasons of the experiment, weekly measurements of the H. halys population were determined. The insect is sucking plants nutrients; therefore, the total chlorophyll content in the leaves of the treatments was recorded weekly. In addition, the percentage of infested kiwifruits was estimated at the end of the experiment. Moreover, to study the biostimulant potential of the formulation, growth measurements on stems and leaves were performed during the experiment. Finally, at the kiwi harvest point, the fruit biomass, dimensions, and weight were obtained, and the leaves’ proline content was evaluated. The results encourage us to further study this EPF formulation as the bioinsecticidal effect was noted by the reduction in H. halys population, and biostimulant action was perceived by the higher plant biomass.

“…In the southern regions of Russia at the beginning of the year 2000, a sharp increase was notable in the harmfulness of Nezara viridula in vegetables, fruits, berry crops, and soybeans. The bugs began to spread from Northern Africa in the second half of the 20 th century as one of the first pentatomides, moving to the North, enhancing its harmfulness to crops (Karpun et al, 2022).…”

Rice grain dark spots are harmful, damaging the grains and, eventually, affecting the grain quality. Dark spots appear due to insect pests of the family Pentatomide, which feed on caryopsis tissues with a bite-puncture from the upper lip of their oral apparatus transformed into a needle. Mechanical damage to the grain leads to the penetration of microbes into the grain tissues, resulting in its darkening. The practical study aimed to determine the effects of the ripening stage on the ratio of dark spots on rice grains and their damage. Experiments assessed the influence of panicle age on rice grain damage caused by the southern green stink bug (Nezara viridula L.). Data recording on various parameters progressed by placing one and three bugs on the rice panicle. After crop maturity, evaluating the cut panicles continued based on empty grain content, grain size, and damaged grains. Other treatments had bugs placed during the flowering and five, 10, 15, 25, and 30 days after. Higher rice grain damage occurs when infested with three stick bugs in the first 10-15 days after flowering, revealing this period was the most vulnerable. Infection at later stages of ripening caused no significant damage to rice grains. The scientific literature does not provide information on dividing rice varieties into groups according to the degree of grain damage in the field in the form of dark spots. Based on the results, groups of pecky rice appeared for the first time according to the degree of damage, depending on the infection period, i.e., surface type, medium degree, and extensive damage type to the rice grains.

Aim. The aim of the work was to study the species diversity of pests of the suborder of shield bugs (Heteroptera) in agrocenoses of the Lazarevsky district of Sochi.This paper presents data on the distribution, abundance and density of Heptoptera pest populations in this location. Heteroptera were gathered twice a month during the growing season (April to October) and weekly in the autumn‐winter period (November to March). The choice of registration date during the growing season was determined by the appearance of the first phytophagous individuals after wintering. Identification of the identified phytophages was carried out in the laboratories of the station according to generally accepted methods.The paper presents data on the distribution, abundance and density of pest populations of the suborder of shield bugs (Heteroptera) in the Lazarevsky district of Sochi, Krasnodar Territory. As a result of this research, the species composition of the most common species of bedbugs in this area has been revealed. The most harmful species noted were: berry shield Dolycoris baccarum Linnaeus, 1758; ornate shield Eurydema ornata Linnaeus, 1758; Green shield Nezara viridula Linnaeus, 1758; ruled shield Graphosoma lineatum Linnaeus, 1758; brown‐marbled bug Halyomorpha halys Stål, 1855; oak lace‐maker Corythucha arcuata Say, 1832; sycamore lace‐maker Corythucha ciliata Say; pear lace‐maker Stephanitis pyri Fabricius and linden bug Oxycarenus lavaterae Fabricius, 1787.As a result of the research undertaken, an increase in the total number of bedbug populations, an expansion of trophic connections, an increase in aggressiveness and a change in the status of individual pest species were revealed.
