فون کنه های شکارگر زیر راسته ی پیش استیگمایان باغ های میوه ی شهرستان تربت جام طی سال های 90-1389 مورد مطالعه قرار گرفت. نمونه ها از شاخه و برگ درختان میوه، علف های هرز و خاک اطراف ناحیه طوقه و سایه انداز درختان میوه جمع آوری شدند. در این بررسی نه خانواده، 16 جنس و 25 گونه جمع آوری و شناسایی گردید که در بین آن ها چهار گونه که با علامت * مشخص شده برای اولین بار از ایران گزارش می شود. اسامی خانواد...
E FFECTIVE POSTHARVEST DISINFESTATION of export fruits from the Western Cape province of South Africa would help to reduce rejections due to the presence of insects. However, there is normally only a limited opportunity between controlling the insects and damaging the produce. A widely used agent in disinfestation procedures, methyl bromide, was scheduled to be withdrawn in many countries in 20...
Monitoring the ability of bacterial plant pathogens to survive in insects is required for elucidating unknown aspects of their epidemiology and for designing appropriate control strategies. Erwinia amylovora is a plant pathogenic bacterium that causes fire blight, a devastating disease in apple and pear commercial orchards. Studies on fire blight spread by insects have mainly focused on pollina...
The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed pollinators such as honey bees, is unclear. We found universally positive associations of fruit set with flower visitation by wild insects in 41 crop systems worldwide. In contrast, fruit set increased significantly with flow...
fruit fly, ceratitis capitata (diptera:tephritidae), worldwide. to determine the best combination of trap and attractant for mass trapping of mediterranean fruit fly, a field experiment was conducted in a randomized complete block design (rcbd) with 6 treatments in 3 replications in a pomegranate orchard in shiraz (iran) in 2009. treatments included: 1-jackson trap baited with trimedlure, 2- mc...
BACKGROUND AND AIMS In the UK, the flowers of fruit-bearing hedgerow plants provide a succession of pollen and nectar for flower-visiting insects for much of the year. The fruits of hedgerow plants are a source of winter food for frugivorous birds on farmland. It is unclear whether recent declines in pollinator populations are likely to threaten fruit-set and hence food supply for birds. The pr...
Microorganisms are acknowledged for their role in shaping insects' evolution, life history and ecology. Previous studies have shown that microbial communities harbored within insects vary through ontogenetic development and among insects feeding on different host-plant species. In this study, we characterized the bacterial microbiota of the highly polyphagous Mediterranean fruit fly, Ceratitis ...
Captures of nontarget insects inside fruit fly (Diptera: Tephritidae) traps placed in native habitats at three localities on Kauai Island, Hawaiian Islands were evaluated. Significantly greater nontarget capture rates were found for traps separately baited with four different attractants, methyl eugenol (five species and two morphospecies), cue-lure (two species), trimedlure (three species and ...
Knowledge of the dielectric properties of commodities and insect pests is important in developing thermal treatments for postharvest insect control based on radio frequency (RF) and microwave energy. The dielectric properties of six subtropical and tropical fruits along with four associated insect pests were measured between 1 and 1800 MHz using an open-ended coaxial-line probe technique and at...
Many insects are influenced by the phenology of their host plants. In North Central Florida, Narnia femorata (Hemiptera: Coreidae) spends its entire life cycle living and feeding on Opuntia mesacantha ssp. lata. This cactus begins producing flower buds in April that lead to unripe green fruit in June that ripen into red fruit through December. Many morphological and behavioral characteristics o...
