Abstract Aphids ( Aphis gossypii) are the main problem in patchouli plants Pogostemon cablin ). The presence of aphids on is very worried by farmers, because it can damage feeding leaf which reduces plant growth. Therefore, neccesary to learn more about biological A. gossypii plants. A was taken from Nino Park, Syiah Kuala University and Lamteuba, Aceh Besar. used result maintaining cuttings fo...

We study the identity-based solution of Witten’s cubic bosonic open string field theory constructed by Takahashi and Tanimoto, which is claimed to describe the tachyon vacuum. We argue that the observables of the solution coincide with those of the tachyon vacuum using the method proposed by Kishimoto and Takahashi. We also discuss how to treat the kinetic term of the string field theory expand...

in several parts of the world, important yield losses are caused to faba bean due to attack by the black bean aphid aphis fabae scopoli. although resistance could be a good alternative to chemical control, its genetic basis is still largely unknown; and its phenotypic expression is still poorly described, making crucial the permanent evaluation of genetic resources available in different countr...

Plant-parasitic nematodes (PPNs) are important pests that cause an estimated ten billion dollars of crop loss each year in the United States and over 100 globally. The Animal Plant Health Inspection Service (APHIS) within U.S. Department Agriculture maintains updates Regulated Pest list. Currently, number PPNs regulated by APHIS includes more than 60 different species. This review focuses on to...
