Abstract | ||||
Chamomile (Matricaria chamomilla) is one of the most important medicinal plants in Egypt. The experiment carried out at Fayoum Governorate during two successive growing seasons, 2104/2015 and 2015/2016, to compare the effects of organic and conventional plantation of chamomile on the occurrence of some sucking insect pests and their natural enemies, spiders (Araneae) were the major and most abundant predators. Aphids, Aphis gossypii Glov. was the major insect pest. Organic plants hosted number of aphids less than conventional plants in two seasons. Thrips, Thrips tabaci Lind., also were higher in number in conventional plants than in organic plants. Plant bug was observed with few numbers in both plantations. Three natural enemies; coccinellid larvae, orius and insect parasites were found in rare numbers for organic and conventional plants throughout the study period. The population density, species diversity, and relative abundance of spiders were studied. Population of spiders was higher in conventional plantation (106 & 114 individ.) than in organic plantation (89 & 97 individ.) in two seasons, respectively, which may be due to the infestation with sucking insect pests that was more in conventional plants than in organic plants. | ||||
