Studies of zoochorous seed dispersal systems often consider crop size, yet seldom consider the kinds and amounts of fruits surrounding parent plants (the fruit neighborhood) when attempting to explain among-plant variation in fruit removal. We studied avian frugivory at 24 Schefflera morototoni trees from February to May 1998 in central Puerto Rico. The number of fruits removed by avian seed di...

Streptomycin has been authorized for restricted use in the prevention of the fire blight disease of pome fruit orchards in the EU and Switzerland. This study addresses the important topic of the influence of the use of streptomycin in agriculture on the total bacteria community within the soil ecosystem. Soil samples were taken from soils under apple trees, prior to streptomycin application and...

We evaluated crop load, fruit yield and size in several grapefruit blocks on the central Florida Ridge and in the Indian River areas over three growing seasons to determine potential causes of elongated, sheepnosed grapefruit. Previous studies showed that relatively higher rates of N fertilization and high early season (February-July) temperatures within tree canopies resulted in high percentag...

This study revealed the tritrophic interactions of predatory coccinellids-host aphids-host plants on pome and stone fruit trees herbaceous in orchards Çanakkale Province, Turkey. Field sampling was done during spring summer seasons 2020 2021. Twelve species belonging to eight genera from family Coccinellidae (Coleoptera) were found interacting with eleven host aphids Aphididae (Hemiptera) plant...

Abstract Brown rot decay of stone and pome fruit caused by Monilinia spp. is an economically important disease. The main pathogens in Italy are the indigenous species laxa M. fructigena, invasive fructicola . presence was reported for first time 2008 Cuneo, Piedmont. Further records showed that spread established rapidly other regions Italy. In South Tyrol, Europe's largest contiguous apple-gro...

Aquatic species in agricultural areas are often exposed to concentrations of pesticides and fertilizers that can affect the entire community. This study aimed monitor presence nutrients (organophosphates carbamates) evaluate their effects on composition macroinvertebrate assemblages at two sites Neuquén River, both upstream (UNR) downstream (DNR) an area intensive cultivation pome fruit trees. ...

Several technologies are being applied for treatment of palm oil mill wastes. Among them, the biological treatments (vermicomposting) have widely been recognized as one of the most efficient and eco-friendly methods for converting organic waste materials into valuable products. The present study focuses on vermicomposting of acidic palm oil mill effluent (POME) mixed with the palm pressed fibre...

Apple proliferation (AP) and pear decline (PD) are the most severe diseases in pome fruit growing areas. AP-infected trees show typical symptoms such as witches’ broom, enlarged stipules, tasteless, and dwarf fruits. PD-infected pears show a progressive weakening, reduced terminal growth, smaller fruits, and die within weeks (quick decline) or years (slow decline). The diseases are caused by th...
