Activity of mediterranean fruit fly, cemtitis capitata wied [diptera: tephritidae], in response to some weather factors at Assuit governorate

A field study was carried out on the population dynamics of the Mediterranean fruit fly [MFF] Cemtitis capitata Wied. males in Assuit governorates [upper Egypt] during 2011/2012 and 2012/2013 seasons in mixed orchards by using Jakson trap. The obtained data revealed that the occurrence of MFF was relatively ail over the two seasons with some exceptions, The abundance of the pest was higher in the second season than that in the first one. The higher appearance of the pest was recorded on September-November in both first and second seasons. Temperature had significant negative correlation [r=0.105] in the first season and insignificant negative correlation [r=0.076] in the first and second seasons, respectively. However, R.H.% had high significant positive [r=0.451] and insignificant positive [r=0.203] in the first and second seasons, respectively. Results obtained could be exploited in management of this insect pest especially, in the control programs

Effect of Eclipta alba alone and in addition to praziquantel in murine Schistosomiasis mansoni

Eclipta alba has been used in traditional medicine for treatment of liver cirrhosis and hepatitis. In this study, Eclipta alba was used alone and in combination with praziquantel. Four groups of Schistosoma mansoni [S. mansoni] infected mice were used and treatment was started 8 weeks post infection. The first was control untreated group, the second praziquantel in a dose of 500 mg/kg orally for 2 consecutive days, the third group treated with Eclipta alba [200 mg/kg for two weeks] and the last group received combined therapy. The results confirmed that Eclipta alba does not have curative properties against S. mansoni in infected mice. However, both alone and in combination with praziquantel, it decreased the level of alanine aminotransaminase [ALT] and leukotrein B4 [LTB4] in serum and the level of reduced glutathione [GSH] and malonaldehyde [MDA] in liver homogenate. It also reduced the hepatic granuloma diameter [37% and 40%, respectively, after 10 and 13 weeks post infection] and reduced the number of eosinophils in these granulomas. On the other hand, praziquantel [PZQ] produced 99% worm reduction and improved the level of ALT,GSH and MDA. The results suggested that Eclipta alba had anti-inflammatory and anti-hepatoprotective effect in Schistosoma mansoni infection and would be a useful treatment after praziquantel treatment

Investigation on the constituents of sesbania aegypiaca as molluscicidal agent

The crude triterpenoid saponins and tannins isolated from the ethanol extract of Sesbania aegyptiaca showed molluscicidal activity against B. alex and rina, LC power down 90 at 40 and 125 ppm, respectively. B- amyrin, oleanolic acid and dustanin were isolated and characterized
