BACKGROUND: Chemical control of spider mites and thrips in everbearer strawberry is difficult as few efficient chemicals are available and residues represent a risk. In the north the success of biocontrol of mites and thrips in open fields compared with tunnels needs to be evaluated. OBJECTIVES: To investigate the need for control of spider mites and thrips and evaluate the effectiveness of bio...

Thrips populations increase in the spring on early wild host plants and most likely on wheat. These hosts of thrips start to dry beginning in early May until midJune and thrips begin to migrate to more favorable food sources. Unfortunately, this is about the same time that cotton begins to grow. The large host acreage for thrips and their reproductive capability create a situation, in most year...

Mulberry is one of the Chinese traditional medicines. But few studies focused on the hypoglycemic effect of Mulberry seed and the possible mechanisms. We identified that mulberry seed is rich in DNJ, the content of which is 0.6015%. Both mulberry seeds powder and its aqueous extract were used to detect the hypoglycemic effect of mulberry seeds. The results indicated that mulberry seeds powder c...

Various traps were evaluated for capture of western flower thrips, Franklinella occidentalis (Pergande). More thrips were attracted to blue sticky cards compared with yellow or white cards. With the addition of blue light emitting diodes (LEDs) thrips numbers on blue cards increased 2.2 fold. The numbers of thrips caught per 10cm on blue sticky cups were 2.4 times more than on blue sticky cards...

We investigated color preference, seasonal abundance, spatial distribution and species composition of thrips in northern highbush blueberries, Vaccinium corymbosum L., in New Jersey (USA). White sticky traps were more attractive to thrips compared with yellow or blue traps. Thrips captures using white sticky traps showed that their flight activity begins 20e30 d after the onset of flowering, wi...

Thrips, in particular Thrips obscuratus, were collected from the flowers of 13 species of trees common in the lowland forest of New Zealand. Many New Zealand trees have flowers which are small, shallow, clustered, and lack bright colours. This un specialized floral form is suitable for pollination by small insects, such as flies and thrips. Thrips obscuratus is among the most frequent visitors ...

BACKGROUND Paper mulberry (Morus papyrifera) pollen is considered to be one of the most clinically relevant aeroallergens in Pakistan. To date, the allergenicity of the pollen has not been investigated. OBJECTIVE To characterize the sensitization profile of mulberry-allergic patients and the proteins of paper mulberry pollen contributing to pollinosis in the Pakistani population. METHODS Pr...

Tomato spotted wilt virus (TSWV) is transmitted exclusively by thrips in nature. A reassortment-based viral genetic system was used to map transmissibility by thrips to the medium (M) RNA of TSWV. To locate determinants of thrips transmission in the M RNA, 30 single-lesion isolates (SLIs) were generated from a single TSWV isolate that was inefficiently transmitted by thrips. Three of the 30 SLI...

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is a well-known onion pest worldwide. Onion thrips cause both direct and indirect damage to onion by feeding and ovipositing on leaves that may cause green onions (scallions) to be unmarketable and dry bulb onion size to be reduced. Onion thrips can also transmit several plant pathogens that reduce onion bulb size and quality. One ...

Onion thrips (Thrips tabaci Lindeman (Thysanoptera: Thripidae)) can be a pest in organic onion production on Prince Edward Island. This study was to examine the effect of planting time and variety on infestation levels and damage by onion thrips on cabbage (Brassicae oleracea capitala (L.)). A field site was planted with 2 main and 8 lesser varieties of cabbage over 4 planting dates. Some varie...
