Abstract Since 2010, the South American tomato moth - Tuta absoluta (MEYRICK, 1917) (Lepidoptera, Gelechiidae) - has been recorded in Bosnia and Herzegovina (B&H) and Montenegro. In 2012, pheromone traps were placed among tomato crops growing in greenhouses and open fields in 14 localities in B&H and Montenegro; the pest was caught at all the sites. Adults were caught in both greenhouses and open fields in Trebinje (B&H) on 4th June 2012 and in Ulcinj (Montenegro) in mid-May. Species identification was confirmed by means of morphological characters of adults and male genitalia. In addition, molecular identification of specimens from B&H and Montenegro was performed using mitochondrial (mtDNA) markers.

В статье представлена информация о происхождении и распространении южноамериканской томатной моли Tuta absoluta Meyrick в мире. По состоянию на конец 2019 года, южноамериканская томатная моль распространена в большинстве стран Южной Америки, в Центральной Америке вредитель отмечен в КостаРике, Панаме и Гаити. В Африке вредитель отмечен в 25 странах. В Азии южноамериканская томатная моль отмечена в Ираке, Иране, Сирии, Турции, Узбекистане, Киргизии, Таджикистане, Азербайджане, Индии, Бангладеш и Непале. Проникнув впервые в Испанию в 2006 году, T. absoluta к настоящему времени широко распространилась в Европе. В России южноамериканская томатная моль была впервые выявлена в 2010 году в республике Адыгея. Дано описание морфологических и биологических особенностей вредителя. Показано распространение и вредоносность томатной моли в Ростовской области РФ. В 2019 году томатная моль распространилась по всей территории станицы Кривянская. Первые признаки повреждения томатов молью в 2019 году отмечали уже с июня, лишь на некоторых отдаленных фермерских участках с июля. Первые очаги в теплицах отмечаются, как правило, на боковых рядах и в углах теплиц. Предложены меры борьбы с вредителем для сдерживания его распространения. Необходим тщательный карантинный контроль продукции и рассады пасленовых культур из зон распространения вредителя, обеспечение пространственной изоляции теплиц от посадок пасленовых культур открытого грунта. Необходимо регулярно уничтожать поврежденные части растений (листьев с минами, плодов с ходами), послеуборочных остатков и пасленовых сорняков. Следует соблюдать плодосмен с выращиванием неповреждаемых промежуточных культур. В течение вегетации необходимо выявлять вредителя и проводить массовый вылов самцов с использованием феромонных ловушек. Международный комитет по предотвращению развития резистентности к инсектицидам рекомендует к применению против T. absoluta порядка 40 препаратов из 12 классов, включая бактериальные.The article deals with data on origin and world distribution of the South American tomato moth, Tuta absoluta Meyrick. At the end of 2019, the South American tomato moth is common pest in most of South America, in Central America, it is noted in Costa Rica, Panama and Haiti. In Africa, the pest has been recorded in 25 countries. In Asia, the South American tomato moth has been recorded in Iraq, Iran, Syria, Turkey, Uzbekistan, Kyrgyzstan, Tajikistan, Azerbaijan, India, Bangladesh and Nepal. Having first penetrated Spain in 2006, T. absoluta has now spread widely in Europe. In Russia, the South American tomato moth was first identified in 2010 in the Republic of Adygea. The description of morphological and biological features of the pest is given. The distribution and harmfulness of tomato moth under conditions of the Rostov Oblast of Russia is shown. In 2019, the tomato moth spread throughout the Krivyanskaya village. The first signs of damage to tomatoes by moths in 2019 have been noted since June, only in some remote farm areas since July. The first foci in greenhouses are noted, as a rule, on the side rows and in the corners of greenhouses. The pest control measures to limit its further spreading are suggested. A thorough quarantine control of products and seedlings of nightshade crops from the pest distribution zones is necessary, ensuring the spatial isolation of greenhouses from planting nightshade crops in the open ground. It is necessary to destroy damaged parts of plants (leaves with mines, fruits with moves), postharvest residues and nightshade weeds regularly. It is necessary crop rotation with the growing of intact intermediate crops. During the growing season, it is necessary to identify the pest and conduct a mass catch of males using pheromone traps. The international Committee for the prevention of insecticide resistance recommends the use of about 40 preparations from 12 classes, including bacterial, against T. absoluta.

Acylsugars present in the accession 'LA716' of Lycopersicon pennellii play an important role in the resistance to Tuta absoluta. This paper investigates the possible association between the resistance to T. absoluta and the acylsugar contents in F2 and F2BC1 tomato plants derived from the interspecific crossing between L. esculentum 'TOM-584' and L. pennellii 'LA716'. From the F2 population, four high acylsugars and one low acylsugars plants were selected and tested for Tuta absoluta resistance along with parental lines TOM-584 and LA-716, and with the checks TOM-600 (high 2-tridecanone line with resistance to T. absoluta) and TOM-556 (low acylsugar line). The genotypes were tested under natural field infestation and were evaluated for overall plant damage, leaflet lesion type and percent of attacked leaflet. Four plants from F2BC1 [=(Lycopersicon esculentum 'TOM-584' <FONT FACE=Symbol>´</FONT> F2)] were selected for high acylsugars and two for low acylsugars, and tested in greenhouse cages infested with T. absoluta. These genotypes were evaluated with the parental lines and the checks for oviposition ten days after infestation, and for leaflet lesion type and overall plant damage at four different dates. The F2 genotypes BPX-370Bpl#25, BPX-370Bpl#30 and BPX-370Bpl#79, the F2BC1 genotypes BPX-370B pl#30-380 and BPX-370B pl#30-271 and the wild accession LA716 had good levels of resistance to Tuta absoluta. The resistance level increased with longer exposition time to the acylsugars, both in the field and in the cage tests. Acylsugar contents seemed to be highly and negatively correlated with the traits related to the pinworm resistance.

Tomato leafminer Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is a key devastating pest worldwide, it has the capacity to develop on a wide range of Solanaceous plants but tomato (Solanum lycopersicum L.) is considered to be its preferred host. This study was carried out at the Agricultural Scientific Research Centre in Latakia in 2019 to estimate biological parameters of T. absoluta and evaluate the effect of temperature in its development, longevity, reproduction in parthenogenesis. The experiments were carried out at constant temperatures (10, 20, 30˚ C), 60-65% RH, and photoperiod (16L: 8D). Biological parameters were analyzed according to the theory of age-stage two-sex life table by using the computer program TWO-SEX MSchart. The highest value of intrinsic rate of increase (r), the final increase rate (λ), and net reproductive rate (Ro) were 0.0439±0.0028 females/female/day, 1.0449±0.0029, and 7.01±0.8705 females/female/generation, respectively, at 20˚C. The lowest value of net reproductive rate (Ro) was 0.92±0.1250 females/female/generation at 30˚C. Generation time (T) was the longest (44.3±0.203 days) at 20˚C and decreased to 26.38±1.156 days at 30˚C. T. absoluta completed its development at all these temperatures. The results obtained showed that the effect of temperature on the insect development from egg to adult decreased with increased temperature. The shortest development period on egg, larva and pupa development was 3.95±0.149, 11.975±0.075 and 4.95±0.086 days, respectively, at 30˚C. This means that the development time from egg to adult was shorter (20.8±1.151 days) at 30˚C as compared to 34.51±0.127 days at 20˚C, and longest at 10˚C (125.4±1.211 days). The female longevity was longer (61.35±0.25 days) at 20˚C. The highest rate of fecundity was 12.98±1.072 eggs/unmated female, and the lowest was 2.19±0.152 eggs/unmated female at 30˚C. Moreover, the unmated females kept at 10˚C did not lay eggs, and unfertilized eggs (asexually produced eggs) laid by unmated females at 20 or 30˚C did not hatch. The adult pre-oviposition period (APOP) of unmated females was 2.57±0.1368 days at 20˚C and 4.31±0.2629 days at 30˚C, whereas the total APOP of females was 36.86±0.1844 days at 20˚C and 24.21±0.3039 days at 30˚C.
