“…An integrated pest management program for apple and cherry orchards was developed in some countries, for example Turkey (Anonymous 2002) and Hungary (Jenser et al 1999(Jenser et al , 2001. In recent years, there has been increasing interest in Wnding a novel, powerful, targetselective, and environment-friendly pesticide to manage S. pyri (Yu et al 2005). There are more studies on Stephanitis pyrioides (Scott), the most important pest of azaleas (Braman et al 1992;Shrewsbury and Raupp 2000;Klingeman et al 2000aKlingeman et al , b, 2001aStewart et al 2002) and some other species, like Corythucha sp., (Braman and Pendley 1993;Rédei et al 2004;Bernardinelli 2006) in the USA and Eastern Europe.…”

Pear lace bug, Stephanitis pyri (F.) (Heteroptera: Tingidae) is a pest of apple and pear trees and ornamental Rosaceae plants in Mediterranean countries and palearctic region. The aim of this study is to determine the eVects of temperatures on S. pyri in the laboratory. Development and fecundity of S. pyri reared on apple leaves (Pyrus malus L.) were investigated at Wve constant temperatures (20, 23, 26, 29 and 32 § 1°C) and a 16L:8D photoperiod. Longevity was determined to be 12.6 days at 32°C and 58.7 days at 20°C for females, and 9.7 and 37.7 days for males. Females laid 186.9 eggs per female with the highest number achieved during 28.5 days of oviposition period at 26°C. Female lifetime fecundity was reduced at 32°C (40.0 eggs per female). While the net reproductive rate (R 0 ) was highest at 26°C, the intrinsic rate of natural increase (r m ) was highest at both 26 and 32°C. The mean generation time (G) was estimated to be 27.2-78.4 days at 20 and 32°C, respectively. The longest development times for egg and total nymph stages were obtained as 22.0 and 24.9 days, respectively, at 20°C. S. pyri developed fastest from egg to egg in 24.3 days at 32°C. The lower developmental threshold (T 0 ) was 9.7°C and the thermal constant (K) was 517.3 degree-days for S. pyri. Thus, S. pyri is calculated to have 3.8 theoretical generations in Tekirdag. The optimum developmental temperature for S. pyri was 26°C.

“…Due to their high nutrition value (high protein, low fat) and pharmacological activities, they have been recognized as one of the Chinese food and also become popular in other countries. For a long time, jellyfish have been employed as traditional Chinese medicine for treatment of high blood pressure, bronchitis, tracheitis, gastric ulcers, and asthmas (Yu et al, 2005a). Recently, the production of jellyfish is subject to considerable fluctuations owing to economic and social causes, some jellyfish are even abandoned because of insufficient processing capability.…”

In order to select an optimum extraction method for the target glycoprotein (TGP) from jellyfish (Rhopilema esculentum) oral-arms, a high performance liquid chromatography (HPLC)-assay for the determination of the TGP was developed. Purified target glycoprotein was taken as a standard glycoprotein. The results showed that the calibration curves for peak area plotted against concentration for TGP were linear (r = 0.9984, y = 4.5895x+47.601) over concentrations ranging from 50 to 400 mgL -1 . The mean extraction recovery was 97.84% (CV2.60%). The fractions containing TGP were isolated from jellyfish (R. esculentum) oral-arms by four extraction methods: 1) water extraction (WE), 2) phosphate buffer solution (PBS) extraction (PE), 3) ultrasound-assisted water extraction (UA-WE), 4) ultrasound-assisted PBS extraction (UA-PE). The lyophilized extract was dissolved in Milli-Q water and analyzed directly on a short TSK-GEL G4000PWXL (7.8 mm×300 mm) column. Our results indicated that the UA-PE method was the optimum extraction method selected by HPLC.

“…Evidence from rat experiments shows that jellyfish can be used to cure arthritis (Hsieh 2001), while other investigators have reported that the various venoms from different jellyfish species have biological functions (Rottini 1995;Gusmani 1997;Li 2005). Moreover, the active protein isolated from jellyfish (R. esculentum) possesses antioxidant and insecticidal activities (Yu 2005a(Yu , b, 2006. It can be concluded, therefore, that the jellyfish has potential applications inhealth protection and in the pharmaceutical, cosmetic, and food industry, while the polypeptides or toxins and collagen extracted from jellyfish may also be have wide applications.…”

“…In addition to studies on its morphology and taxonomy (Calder 1973;Hong 1978;Johnson 2001), many studies have been carried out on the biological and pharmacological properties of jellyfish venoms (Li 2005;Yu 2005aYu , b, 2006. As a rather unique diploblastic animal, the jellyfish plays an important role in our study of the origin and evolution of the mesoblast and muscle cells (Müller 2003;Spring 2002;Seipel 2005).…”

The jellyfish is a popular seafood in eastern and southern Asian nations where there is a high market demand that stimulates large-scale jellyfish production. Due to its economic importance in China, many biological studies have focused on the jellyfish Rhopilema esculentum Kishinouye in terms of the environmental impact of aquaculture activities and culture techniques. In recent years, the commercial aquaculture of R. esculentum has expanded greatly in China. This paper summarizes the current status of research in China on R. esculentum and associated aquacultural practices, focusing on a number of related technological approaches.
