![]() Such studies revealed that Drosophila melanogaster and Caenorhabditis elegans expressed similar components in the insulin signaling pathway. Nutrigenomics examines how nutrition affects gene expression patterns, and it offers a means to measure an insect’s response to changes in the food stream and can provide information about diet limitations. Understanding the insect diet is difficult because the physiological and biochemical processes that regulate insect populations are poorly known, and physiological or biochemical markers that can be used to evaluate the suitability of a particular type of nutrition are lacking. Since the 1950s, researchers have been trying to develop an effective artificial diet for rearing ladybug, it was still difficult that can reproduce these insects at a large scale. Therefore, the availability of artificial diets is crucial for successful mass rearing of C. septempunctata is reared mainly using aphids as food, but this method is costly and time-consuming because it requires mass rearing of both aphids and C. septempunctata in the field to control pests effectively, it is necessary to rear them artificially. Because climate, farming operations, and abuse of pesticides make it difficult to maintain sufficient numbers of C. It has received increasing attention as a bio-control agent due to its strong predatory ability against many important types of pests, including aphids, whiteflies, spider mites, leafhoppers, and psyllids. (Coleoptera: Coccinellidae), is a natural enemy of insect pests. The lady beetle, Coccinella septempunctata L.

Lowest number of beetles was recorded on IBGE-II. Maximum number of bio-control agents was recorded on IBGE-I followed by IBGE-III and IBGE-IV. IBGE-I was also found superior in terms of bio-control agents. IBGE-II showed least resistance against Lipaphis erysimi, which was found to be most susceptible cultivar by recording highest mean number of aphid’s population on it. Among all the Brassica lines, IBGE-I showed comparatively more resistance by recording least number of aphids on it as compared to IBGE-III, IBGE-IV and IBGE-II. septempunctata (1.32 ladybird beetle plant -1) was recorded on the 3rd week of March. At the time when aphid’s population started to increase, the peak population of C. The specie of ladybird beetle (Coccinella septempunctata) was first time appeared on 14 th February with mean number of (0.22 ladybird beetle plant -1). The peak population of 2.47 aphid’s leaf -1 was recorded during 3 rd week of March and lowest population of 1.67 aphid’s leaf -1 was recorded during 2 nd week of April. The data revealed that aphid’s infestation invariably started in all four varieties during 2 nd week of February 2013 (1 st observation). Four different brassica lines IBGE-I, IBGE-II, IBGE-III and IBGE-IV were used, which were replicated four times in Randomized Complete Block Design. Studies regarding the determination of population trend of Lipaphis erysimi (Kalt) and its associated bio-control agent, Coccinella septempunctata (Linnaeus) in different brassica lines, were conducted at the New Developmental Farm, The University of Agriculture Peshawar during cropping season (2012-2013).
