In this study,we monitored for the impact of three aqueous extracts of plants(Azadirachta indica,Hyptis suaveolens and Solanum lycopersicum)on insect pests abundance in okra(abelmoschus esculentus L.)crop,compared to a synthetic chemical«SAUVEUR 62 EC»,having as active ingredients,acetamiprid 32g/l and Lambda-cyhalothrin 30g/*** applications by these extracts were done using manual *** treatment,the insects were caught using two methods(pitfall traps and colored bowls traps).A total of 6505 insects belonging to nine orders were recorded in four *** plot 1(9 orders)was the most diverse,followed by the plot 3(8 orders),the plot 2 and 4(7 orders respectively).Coleoptera,Lepidoptera,Diptera,Orthoptera and Hemiptera were the most *** chemical treatment has impacted significantly the number of orders(p<0.05)but,the insect abundance was impacted significantly by the different biological treatments(p<0.05).This study showed that the aqueous extract of Solanum lycopercicum was more effective on the abundance of pests belonging to Hemiptera,while the aqueous extracts of Azadirachta indica and Hyptis suaveolens were effectives on the abundance of pests belonging to *** chemical treatment was effective on the pests belonging to both orders.

OBJECTIVE： Helicobacter pylori is a Gram-negative organism. Its outer membrane protein Q（Hop Q） mediates host-pathogen interactions; Hop Q genotypes 1 and 2 are found associating with gastroduodenal pathologies. The authors measured the anti-adhesion effects of the extracts of abelmoschus esculentus, Zingiber officinale, Trachyspermum ammi, Glycyrrhiza glabra, Curcuma longa and Capsicum annum against Hop Q genotypes and H. pylori cytotoxin-associated gene A（Cag A）.METHODS： DNA was extracted by polymerase chain reaction of the Hop Q genotypes（i.e., type 1, type 2 and Cag A） from 115 H. pylori strains. The effect of the extracts from selected dietary ingredients was determined using a gastric adenocarcinoma cell line and a quantitative DNA fragmentation assay. The anti-adhesive effect of these extracts on H. pylori was tested using an anti-adhesion ***： C. annum, C. longa and A. esculentus showed prominent anti-adhesion effects with resultant values of 17.3% ± 2.9%, 14.6% ± 3.7%, 13.8% ± 3.6%, respectively, against Hop Q type 1 and 13.1% ± 1.7%, 12.1% ± 2%, 11.1% ± 1.6%, respectively, against Hop Q type 2. C. longa（93%）, C. annum（89%） and A. esculentus（75%） had better anti-adhesive activity against H. pylori with Hop Q type 1 compared to Hop Q type 2 with respective values of 70%, 64% and 51%. Extracts of C. annum（14.7% ± 4.1%）, A. esculentus（12.3% ± 4.1%） and Z. officinale（8.4% ± 2.8%） had an anti-adhesion effect against Cag A-positive H. pylori strains compared to Cag A-negative strains.
