This research aims to extract neem oil from kernels of Neem seed. The extracted was used for bio-pesticide control pests. An presser machine extraction the oil. results obtained showed that an average 140ml/kg seed kernel. based insecticides are botanical pesticides safer environment and public. Various studies have shown is non-toxic birds, beneficial insects. Moreover, can be as fungicide, in...

In order to improve the recognition rate and accuracy of stored grain pests classification, saving classification time, a new recognition method based on the Gabor wavelet and sparse representation is proposed in this paper. In this paper, nine typical pests in the stored grain are regarded as the research object, Gabor energy features and morphological features are extracted, principal compone...

Common methods of weight loss assessment in stored grain include the standard volume weight (SVW), count and weigh (C&W), the thousand grain mass (TGM) and the indirect with a conversion factor (CF) which have been used in varying storage environments. Apart from accuracy and reliability, practical application may limit their use in rural areas. Three of the methods: (SVW) or Bulk density (BD),...

Abstract Corn is one of the word’s most essential carbohydrate-producing food crops. In addition to being used as a staple for world’s population, corn seeds are also an component animal feed. The purpose this study was determine effect drying and storage time on presence warehouse pest populations. research method carried out by under sun exposure 6 hours/day. experiment consisted four treatme...

Exotic forest pests cost China and the United States billions of dollars each year. Current regulatory systems worldwide are overwhelmed with the increasing volume of international trade. Trade in nursery stock, wood products, pallets and dunnage have proven the most common means of transport for exotic forest pests. Despite our best efforts, pests such as chestnut blight, gypsy moth, Dutch elm...

The endoparasitoid Microplitis prodeniae Rao and Chandry is an important potential augmentative biological control agent for lepidopteran pests of vegetables and tobacco. However, cold storage of pupae is required to ensure that sufficient parasitoids are available when they are needed in the field. In this study, pupae were maintained at 0, 4 or 10°C for 5-50 days after which the adults were e...

The major storage proteins in cereals, prolamins, have an abundance of the amino acids glutamine and proline. Storage pests need specific digestive enzymes to efficiently hydrolyze these storage proteins. Therefore, post-glutamine cleaving peptidases (PGP) were isolated from the midgut of the stored-product pest, Tenebrio molitor (yellow mealworm). Three distinct PGP activities were found in th...
