“…The occult spread of the invasive brown marmorated stink bug, Halyomorpha halys, in Sardinia (Italy) agricultural productions potentially threatened by the brown marmorated stink bug which is able to damage almost every fruit or seed of agricultural importance including rice (Lupi et al, 2017). Moreover, this bug is also able to become a key pest of additional crops in invaded countries (Lee et al, 2013).…”

The invasive brown marmorated stink bug, Halyomorpha halys (Stål, 1855) (Hemiptera Pentatomidae), was recorded in autumn 2018 in Sassari (northern Sardinia, Italy), after a previous finding in Cagliari (over 200 km away in southern Sardinia) in autumn 2016. It is not clear whether the species has already spread throughout the Sardinia or whether the sighting in the North of Sardinia is due to a second introduction. However, it is usual for this species to have a long period with low population level after its first introduction into a new area. The presence of this very polyphagous alien species is a serious hazard for Sardinian agriculture.

“…In Russia, its first recorded emergence transpired in 2014. In Northern Italy, the first evidence that damage the rice grains in panicles appeared in 2017 (Lupi et al, 2017). The first sighting of Hypatropis inermis in highland rice (cultivar Cambará) in Novo Progresso, State of Pará, Brazil, came out, and the search for insect pests commenced in 2010 and 2011 using entomological grids and visual searches in rice plants (Krinski et al, 2015).…”

Pre-Harvest Dark Spots Harm the Rice Grains Qualitatively and Quantitatively

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.

Halyomorpha halys (Stål) (Heteroptera: Pentatomidae) has brought about agricultural harm throughout the Eastern Black Sea coastline since 2017. It continues to come to a threat because there are no adequate studies on managing this pest. One of the major rein strategies of insecticides is acetylcholinesterase (ACHE) inhibition. Therefore, this study aims to investigate an alternative way to struggle H. halys by inhibiting ACHE. The ACHE was purified from H. halys using edrophonium-Sepharose 6B affinity chromatography and characterized by examining some kinetic properties. The molecular weight of the purified enzyme was determined by Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis and natural polyacrylamide gel electrophoresis. In addition, the inhibitory effects of tacrine and edrophonium chloride, and water extracts of olive leaf, walnut leaf and alder leaf on this ACHE were investigated. The acetylcholinesterase was purified 403-fold with an 83.3% yield. H. halys ACHE was found to have six subunits and a molecular weight of approximately 350 kDa. The ACHE’s Km, Vmax, and kcat values were assigned to be 0.02 ± 0.006 mM, 3,333.3 ± 481 EU.mg protein− 1, and 1070.2 ± 184 min− 1, respectively. All inhibitors highly inhibited of activity of h.halys ACHE. Especially, the fact that the water extracts of these plants are effective in ACHE inhibition is significant due to being environmentally amicable pesticides that may be benefited in the struggle with the pest.
