The occurrence of fringed wings insect, Pseudodendrothrips mori is a major pest of mulberry, which causes a considerable leaf yield loss and inturn damages its quality. Hence, an attempt was made to know the changes in biochemical constituents (Free amino acids, total soluble proteins, total reducing sugars, total soluble sugars, starch and total phenols) and photosynthetic pigments (total chlo...

in mulberry orchards in northern part of iran, thrips is a dominant pest and causing a lot of damage to the mulberry. the effect of pest on bio-chemical parameters of mulberry leaf of two varieties viz. kenmochi and ichenoise and also the effect of feeding of infested leaves on rearing performances have been studied. for the study, six plots of 200 m2 area of both the varieties were selected an...

Mulberry (Morus spp.) is the only food plant for the silkworm, Bombyx mori Linn., which is an economically important insect for sericulture industry. Mulberry is attacked by a number of insect pests, parasites, predators and pathogens around the year which not only affect the leaf quality but also responsible for poor yield. Mulberry is reported to be attacked by more than 200 species of insect...

Two species of Thripinae described from China, Danothrips dianellae Zhang and Tong, and Taeniothrips calopgomi Zhang, are here recognized as synonyms of two widespread Southeast Asian species.

Onion thrips, Thrips tabaci Lindeman, are an economic pest of alliums worldwide. In Ontario onion-growing regions, seasonal abundance and population trends of onion thrips are not well known. The objectives of this research were to investigate onion thrips population dynamics by using both white sticky traps and plant counts, to gain insight into flight height, and to determine the genus and se...

Mulberry (Morus spp.) is a widespread deciduous tree and its fruit is commonly eaten in Korea and eastern Asia. Some reports demonstrate that mulberry fruit is a food allergen in the Mediterranean area. However, there has been no report of systemic allergic reactions after ingesting mulberry fruit in Korea. An 18-year-old boy with a mulberry fruit allergy visited our allergy clinic. He had expe...

Seasonal abundance and effect on onion yield reduction were studied for onion thrips, Thrips tabaci Lindeman, for two consecutive seasons (dry and rainy) to develop economic thresholds (ET) in Honduras. Overall, thrips populations were highest during the dry season, with average thrips per leaf per day 5.2 times higher than during the rainy season. In the two onion cultivars tested (Granex 429 ...

Environ Entomol 17(3). 551-559 (1988) ABSTRACT The season-long population dynamics and within-plant distribution of the thrips Frankliniella occidentalis (Pergande) were examined. Thrips density was highly variable and peaked in midseason. Fluctuations in density in combination with changing age structure of the population suggest that migration plays an important role in the population dynamic...

Thrips-borne tospoviruses cause numerous plant diseases that produce severe economic losses worldwide. In the disease system, thrips not only damage plants through feeding but also transmit causative agents of epidemics. In addition, thrips are infected with tospoviruses in the course of virus transmission. Most studies on the effect of tospoviruses on vector thrips have focused on the Tomato s...
