Strawberry is the most spreaded small fruit crop in many countries. In Ukraine sn 2018 this crop total area was 8.3 thus. ha, among them 7.9 thus. ha fruit-bearing in all the categories of farms. The gross berries output was 62.3 thus. tons, the average yield being 7.7 t/ha. The Dutch bank «Rаdobank» carried out in April of 2016 the researches on the small fruit production in Europe and revealed that strawberry even now is the most popular small fruit crop. The strawberry Ukrainian and foreign cvs and elite forms were studied applying the methods of the primary strain inves-tigation and state strain testing in the small fruit patches planted in2012-2016 under the field conditions of the Northern part of the Ukraine’s Lisosteppe, namely: at the Institute of Horticulture NAAS of Ukraine. The varieties – standards were the Ukrainian Hercules, English Elegance, Dutch Elsanta and Italian Alba. As a result the new middle-ripening Ukraini-an cultivar Perlyna was selected as the best according to its signs. Perlyna was obtained by means of the intervarietal hybridization (cvs Present and Elsanta) sn 2004. The authors are V.V. Pavliuk, K. M. Kopan, V. H. Kopan. The berries ripe 2-3 days later than ’Elsanta’ and 2-3 days earlier than and ’Polka’. The bushes are high and vigour, not branchy, with firm high floriferous shoots and dark-green hardish leaves. Resistance to the leaves diseases is high. The berries are high marketable and large (the mass of average is 15 g, maximum 35 g), prolonged broad-conic, being ripe fully dark-red brilliant. The flesh is dense red aromatic of kind sour-sweet taste, in accordance with the multi-year data it contains 7.5 % of dry substances, 3.5 % of sugars, 0.95-1.0 % of organic acids as well as 0.440 mg of pectine substances and 45 mg of vitamin ’C ’ per 100 g of . Under the sufficient humid content the berries size exceeds that of ’Prysviata ’, ’Zenga Zengana’ and ’Polka ’. The yield is higher (18-20 t/ha) than that of the varieties ’Elsanta ’and ’Present ’ under the one-row planting ( 0.8x0.25 m). The cultivar is winter-hardy and drought- resistant. ’Perlyna’ is entered into the State Register of Plant Varieties Suitable for Dissemination in Ukraine. Certificate 181079 on the State Registration of the Plant Cultivar (December 4, 2018). Patent 190373 on the Plant Cultivar (April 12.2019).

The recently introduced spotted wing drosophila is one of the most serious pests in small fruit production in the United States and Europe. Most control relies upon multiple applications of synthetic insecticides. In an effort to find less-toxic insecticides to consumers, farm workers, and wildlife, we conducted two laboratory trials and a semi-field trial in order to assess the potential for disodium octaborate tetrahydrateformulated and sold as Octabor®(U.S. Borax, Inc.) as a control for spotted wing drosophila in wild blueberry. We found that Octabor at 0.6 and 1.0% (w/v) applied to wild blueberry fruit resulted in higher mortality of flies than non-treated control fruit. Addition of sugar to Octabor enhanced mortality in one of the two trials, with an interaction between sugar addition and Octabor rate suggesting that the addition of sugar provided the greatest enhancement at the low rate. Our semi-field study showed that an apparent repellency effect of Octabor provided protection of fruit from infestation for up to 3 days. Also in the semi-field study, we observed a delayed effect on fly mortality. Increased fly mortality occurred over time, relative to the non-treated control fruit. The greatest fly mortality, relative to the non-treated control, resulted from flies being exposed to fruit treated 3 and 7 days prior to fly exposure, but not immediately after the treatment of Octabor. We speculate on why this type of delay in mortality might have occurred.

Abstract Fruits of thirty-five cultivated native plant species (19 orders and 12 families) were sampled in farms of fruit production from two municipalities of São Paulo state, Brazil (January 2010 to March 2012) to evaluate species diversity of Neosilba flies. Thirty-one species of plants were the host for Neosilba species while four were not infested. Some aspects of the biology and patterns of species diversity, abundance, infestation rates, puparias viability and the interactions among species of frugivorous flies and their host plants were quantified. Seven species of Neosilba were reared: Neosilba bella Strikis & Prado (4 hosts), Neosilba certa (Walker) (4 hosts), Neosilba glaberrima (Wiedemann) (5 hosts), Neosilba inesperata Strikis & Prado (6 hosts) Neosilba pendula (Bezzi) (15 hosts), Neosilba pradoi Strikis & Lerena (8 hosts) and Neosilba zadolicha McAlpine (26 hosts). The association between the lance flies and the host fruit species is discussed.

High tunnels are a relatively economical form of protected culture, and offer cultural advantages such as protection from the elements and an extended production season. Interest in high tunnels for small fruit production has been increasing in North America. Growers in the United States and Canada are using multi-bay and single-bay high tunnels for production of red raspberry (Rubus idaeus), black raspberry (Rubus occidentalis), blackberry (Rubus subgenus Rubus), strawberry (Fragaria ×ananassa), and blueberry (Vaccinium spp.). Research trials using high tunnels are being conducted in numerous places across the United States. In most instances, high tunnels increased yields of berry crops, improved quality, and decreased the incidence of most diseases compared with field production, powdery mildew (Sphaerotheca macularis) being a notable exception. The insect and mite complex encountered in tunnels when growing berry crops has changed markedly, often becoming similar to that which might have been expected in greenhouses, with numbers of two-spotted spider mite (Tetranychus urticae), whitefly (Aleyrodidae), and thrips (Frankliniella spp.) reaching high levels without control measures. In studies at The Pennsylvania State University, primocane-bearing cultivars of red raspberry plants produced at least two to three times as much marketable fruit in tunnels as in a previous field study, with substantial summer and fall crops obtained. ‘Triple Crown’ thornless blackberry produced very high marketable yields in the tunnels, even though winter injury historically resulted in a lack of blackberry production in the field. Strawberry production in a plasticulture system using short-day or day-neutral cultivars was found to be viable; however, the primary benefit of high tunnels for strawberry may have been reliability of production rather than a yield increase. Potential reasons for improvements in productivity and quality are numerous and warrant further attention.

Taken together, symptoms present, microscopic characterization, and ITS-1 sequence data indicate New Mexico garlic samples infested with Ditylenchus dipsaci, making this the first known report of this pest in the state. This discovery is significant because D. dipsaci can be a persistent pest and has the potential to cause significant economic losses on agronomically important hosts including onion, garlic, and alfalfa. Its longevity in the soil and international trade issues will be concerns for producers. Monitoring of production areas in the region will be performed to determine if this was an isolated and contained introduction or if this important pest has become established in New Mexico.
