To avoid these disadvantages, laboratory experiments were carried out to evaluate two materials namely, plant oil (Orange oil) and bioinsecticide, spinosad as stored wheat grain protectants against T. castaneum and R. dominica   using two bioassays technique, mixing with medium and repellency at different exposure periods (72 h for mixing with feeding medium and 24 h for repellency).  Results obtained revealed that the two tested materials, orange oil and spinosad had moderately action on the two tested insects either by mixing with medium or by repellent bioassay methods. Data cleared that the effect of the tested materials increased with the increasing of concentration and period of exposure especially with mixing bioassay. For repellent effect, the highest level of concentration had the most action on both T. castaneum and R. dominica.

Spinosad showed nearly similar effect on the two tested insects while R. dominica was found to be more tolerant than T. castaneum with orange oil.

Although a predatory successfully completed its life cycle exclusively on this prey, the rate of predation, life cycle, and oviposition were  varied under different temperatures, whereas the predation rate listed 48  egg/individual and 57.71 egg / individuals at 25 °C and 30 °C, respectively,  while the life cycle period was durated 16.05 days and 11.93 days,  respectively. At the same previous conditions, the oviposition rate was durated 2.28 egg/day and 3.11 egg/day, respectively. Therefore, the predatory mite could play an important role in checking the population of  Lepidopteran pest. }, keywords = {biological control,laboratory,Stigmaeid mites,Egypt,date palm}, url = {https://jppp.journals.ekb.eg/article_87885.html}, eprint = {https://jppp.journals.ekb.eg/article_87885_e9b97f6a092836a3316f35c99dab4180.pdf} } @article { author = {Youssef, Sahar}, title = {COMPOST INDUCED CHANGES IN SECONDARY METABOLITES DURING THE INTERACTION BETWEEN POTATO PLANTS AND THE BACTERIAL WILT PATHOGEN Ralstonia solanacearum}, journal = {Journal of Plant Protection and Pathology}, volume = {5}, number = {1}, pages = {159-171}, year = {2014}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3677}, eissn = {2090-3758}, doi = {10.21608/jppp.2014.87888}, abstract = {The aim of this investigation was to study the interaction between the bacterial wilt pathogen Ralstonia solanacearum and potato Solanum tuberosum plants in relation to plant growth, secondary metabolism and antioxidant system in response to compost application. Single potato eyepieces were germinated and grown in pots containing sandy soil with or without compost at a rate of 7.5 g kg−1 soil. Non-compost- and compost-treated plants (CTP) were inoculated with R. solanacearum 21 days after planting and then were subjected to biochemical analysis and growth parameters determinations after 14 days of inoculation. The obtained results revealed that pathogen infection caused a remarkable decrease in plant growth related parameters and an increase in disease incidence. However, compost substantially improved plant growth and decreased disease incidence. Data also indicated that there were significant  increases in salicylate (SA), phenolics, flavonoids, lignin, and DPPH (2,2-diphenyl-w1-picrylhydrazyl) activity in infected CTP compared with infected non-CTP. In addition, other biochemical indicators of  potato enzymatic activities of glucose-6-phosphate dehydrogenase (G6PDH), shikimate dehydrogenase (SKDH), phenylalanine ammonia-lyase (PAL), cinnamic alcohol dehydrogenase (CADH), polyphenol oxidase (PPO), and guiacole peroxidase (GPX) in infected CTP were significantly higher than those in the infected non-compost-treated ones, indicating induction of critical metabolites playing major roles in plant defense to pathogen. Taken together, the results suggested that compost provides effective protection against the Ralstonia bacterial pathogen via stimulating growth and inducing production of secondary metabolites}, keywords = {}, url = {https://jppp.journals.ekb.eg/article_87888.html}, eprint = {https://jppp.journals.ekb.eg/article_87888_dd806ad7eb0a70e26ee2eb917cd5448d.pdf} }
