Corresponding Author E-mail: [email protected] Aphids are the major pest on crops. Use of chemical pesticides create problems. Chemical pesticides affect the human health, environment and also affects non target organisms. Natural insecticide produced from plants are more promising. The Cymbopogon citratus and Hibiscus rosa sinensis are very important plant which have great effect on insects. The aim of this review to tell about essential oil and extracts which affects insect growth and how much it is ABSTRACT effective. The problem of agriculture crop was pests and these pests are responsible for damaging crops and effect nutritive value. Lemon grass oil repels insects like mosquitoes, aphids due to which it contains citral and also myrcene, citronella, citronellol, and geraniol. The essential oil is derived from aromatic plants has observed as risk free alternatives. Keywords : Aphids, lemongrass, Hibiscus rosa and essential oil. Introduction bamboo like stem, shoot (Siddiqui et al. , 2019). Aphids are tiny sap sucking insects and it belongs to super family Aphids are major agricultural pests that cause important aphidoidae. In Egypt legume crops is infested by sucking production losses of crop plants by causing the damage both through the direct effects of feeding and by vectoring insect called Cowpea aphid (Aphis craccivora, Koch) harmful plant viruses. Aphids have distinctive traits for Homoptera: Aphididae. They feed on sap sucking plant and deform plant structure like curling leaves, inhibiting shoot identifying and exploiting their host plants including the growth and decreasing last production and plant strength expression of polyphenisms a form of discrete phenotypic (Abbas et al. , 2016). Many aphids transmit plant diseases like plasticity characteristic of insects taken to extreme in aphids soybean mosaic virus (SMV). Good example of aphids is A (Yu XD et al. , 2016). Aphids are damaging pests on the et plants. Aphids use their stylets to enter the plant tissue to Craccivora which are causing problems of legumes (Abbas al. feed on phloem sap. In addition, some aphids vector , 2016). Throughout the world cabbage aphid are present, Brevicoryne brassicae L. is found in brassica crop and cause important viral diseases of plants (Nalam, 2019). The damage serious destruction and outbreaks. First time in Europe this of aphids is among the most serious of agricultural and aphid was recognized and after that reported other countries horticultural problems. A pest aphid species may affect either of world with temperate climate. The yield loses in many very specific types of crops or a group of related crops hosts example Crucifera or may be quite polyphagous within and cruciferous crops due to aphids feeding on young leaves. between plant families. Aphids cause damage and lower Aphids pick up virus by diseased plant and bring to healthy plants by feeding and cabbage aphids are responsible for it. agricultural yields in several ways they can grow to high Black bean aphids are found on beans, peas, beets, potato, population densities, removing plant nutrients and may also tabaco and many other host plants. These aphid transfer forty damage plants by removing enough sap and hence lead to withering and then death. Salivary secretion of some aphids plant viruses.

The most New sources are being rapidly examined (Chalise et al. , serious posed by aphids is the vectoring of plant viruses. 2019). Virus infected plants often show an aphid yellowing and have increased free amino acids. Aphids also affects the Cymbopogon citratus belongs to the family poaceae and changing the host metabolism to their advantage and hence order is poales. Cymbopogon citratus , is famous for take over the plants physiological functions (Sorensen, agricultural plant, it is found in India and Srilanka. Parts of 2009).
