Brevipalpus yothersi Baker (Acari: Tenuipalpidae) is reported for the first time on cocoa, Theobroma cacao L. (Malvaceae) in northwestern Peru. Mites were collected from organic cocoa smallholdings September to December 2020 eight localities (three Provinces) of Piura Department. The highest mite population density was found peduncle and epicarps fruits different phenological stages, lowest lea...

intra-specific variations in apex development of two salt-tolerant cultivars (cross rowshan 11 (cr) and kharchia-65) and one salt-sensitive cultivar (ghods) of spring wheat (triticum aestivum l.) grown in sand culture at selected levels of salinity (0, 100, 200, and 300 mol m-3 nacl and cacl2 in 5:1 molar ratio) were studied. to determine the apex lengths and the number of spikelet primordi...

to describe the morphological and histological changes during the annual reproductive cycle of the gonads of cyprinion tenuiradius, a total of 341 specimens (102 female and 235 male specimens) were collected monthly from the rudbal river (in the qarah aghaj sub-basin, the persian gulf basin), firuzabad, fars province, southern iran. the randomly sampling was adequate to collect males and female...

A newly developed wheat cultivar NARC 2011 was evaluated for physioagronomic traits by varying Humic acid concentrations and Effective microbes at different phenological stages during rabi season of 2010-11 in the field area allocated to national coordinated wheat program of national agricultural research centre, Islamabad. The experiment was laid out using randomized complete block design (RCB...

The present study aims to investigate the structure and trend of climate parameters affecting grape growth in Khorasan Razavi (north eastern Iran) in the period of 1991-2015 in 8 weather stations. Effective climate elements such as temperature, precipitation, the number of hot days, the number of frost days, sunshine hours and parameters such as maximum temperature, annualaverageannual average ...

background: thymus daenensis is on e of the endemic aromatic species in iran that its essential oil is used in food and pharmaceutical industries. objective: in this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. methods: the aerial parts of th. daenensis were collected in three stages of plant gr...

Field studies have demonstrated mixed success in trap cropping to manage Crocidolomia pavonana ( binotalis) [F.], a major pest of cruciferous crops in Asia. A possible explanation for this is an inßuence of host plant phenology on oviposition preference. We tested this in simultaneous two-choice oviposition bioassays under laboratory conditions. In cylindrical cardboard experimental arenas, wit...

Knowledge about the fungal spores most abundant in the atmosphere of a vineyard is of great use since it allows development of prediction models of the spore concentration, and therefore application of phytosanitary treatments only when high levels of fungal propaguls are detected. In this study the concentration of phytopathogenic spores is related with the different phenological stages of the...
