In vegetables, as well as in other crops, insect pests cause yield losses, therefore, in the search to solve this problem and as part of an integrated pest management, this research aimed to evaluate trapping efficiency of sticky traps for phytophagous insects present in leafy vegetables. For this, traps of different colors were installed in chard crops (Beta vulgaris), cabbage (Brassica oleracea var. capitata), lettuce (Lactuca sativa) and coriander (Coriandrium sativum). The most common insects were thrips (Frankliniella sp.), Cicadelline leafhoppers (Borongonalia sp.), aphids (Myzus persicae and Myzus sp.), psyllid (Russelliana sp.) and root fly (Diptera-Anthomiidae). Light blue and white sticky traps, show capture efficiency for thrips in 30% and 28% respectively; adults of root fly were captured with efficiency of 23% of all insects on white traps and 17% on light blue traps.

Corn (Zea mays L.) is a cereal of global importance for its different industrial uses and nutritive value. Like other crops, it is affected by pests, including nematodes, whose presence in the maize crop causes a decrease in yields, so the present work is presented. In order to determine the population density of nematodes associated with maize cultivation in the regions of Puno and Cusco; For which 121 soil samples were collected during the 2015-2016 campaign in the Puno Region, in the districts of Chupa, Sandia, San Juan del Oro, Cuyocuyo, Ayapata, Ollachea and San Gabán; And 30 samples from the Cusco Region, in the districts of Pisac and Urubamba. Were identified the genera genera Helicotylenchus spp. and verified. (32-100%), Mesocriconema spp. (33.3-63.8%), Globodera spp. (96-100%), Xiphinema spp. (11-36.6%), Rotylenchus spp. (2...

Phytoparasites such as nematodes attack without showing signs of symptoms, while they can prevent the passage of nutrients and the normal growth of the plant. In the region of Puno, the genus Globodera spp. is the most important pest, however there are no reports for Meloidogyne spp. Thus, the objective of this research is to identify the different genera of phytoparasite nematodes in the cultivation of quinoa in the main production areas of the Puno region. Soil samples were collected in the provinces of Puno, Huancané, San Román, Chucuito, Collao, Yunguyo and Azángaro. Nematode extraction from soil samples was carried out by the centrifugal fluctuation method with sucrose and mounted on permanent sheets for morphological studies.The genera of phytoparasite nematodes identified were Meloidogyne spp., Nacobbus spp., Pratylenchus spp.,&...

Cucurbitaceae contribute to the diet of the population, as well as to the economy of farmers; but are harmed by phyto-parasites like to Meloidogyne spp. The know about the root-knot nematode is empty to put suitable strategies to management. The objectives of this research were identified species of Meloidogyne genera in cucurbitaceaes and determine their distribution and occurrence in Arequipa, Peru. Roots of Cucurbita maxima, Citrullus lanatus, Cucumis melo and Cucurbita pepo were collected, identifying them by electrophoresis for the enzyme esterase. Meloidogyne spp. is present in 87.1% from places that were evaluated and M. incognita I1 (Rm: 1.00), M. incognita I2 (Rm: 1.02 - 1.07), M. incognita S2 (Rm: 0.87), M. arenaria A1 (Rm: 1.19), M. arenaria A2 (Rm: 1.19 - 1.25), M. hapla H2 (Rm: 0.95) and one specie atypical of Meloidogyne (Rm: 0.87) were identified with occurrences of 17.14%...

Potato consumption occurs throughout the Altiplano of Puno and among the organic wastes produced daily at home is potato peelings. The objective of this research is the production of tubers from buds present in potato peels with four strains of Trichoderma sp. The study was carried out under an experimental design with four strains of Trichoderma sp, in a randomized way with a total of 5 treatments that were distributed with two repetitions with a total of 12 experimental units, the potato peels with buds were selected, including a fertilization with four native and commercial strains of Trichoderma, some of them were codified since the species has not yet been identified, to support the growth of seedlings so, in this way, it gives value to the "organic production". The results found evidenced that the greater quantity of tubers was obtained with the strain of Trichoderma sp. 3 with 121...
