abstract indian meal moth, plodia interpunctella hübner (pyralidae) is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repel...
The growing demand for reducing chemical inputs in agriculture and increased resistance to insecticides have provided great impetus to the development of alternative forms of insect-pest control. Myco-biocontrol offers an attractive alternative to the use of chemical pesticides. Myco-biocontrol agents are naturally occurring organisms which are perceived as less damaging to the environment. The...
Abstract: In the present paper, we give a necessary and sufficient condition for contact CR-warped product to be contact CR-product in Kenmotsu space forms.
Background: Nowadays stored–product insect pests are controlled by pesticides and chemical fumigant compounds. The continueous use of chemical pesticides is harmful for non–target creatures specially humans and other mammals. Beside they polluted the environment. Objective: Accoring to the studies, the essential oil of Labiatae plants have insecticidal activity against some pests. In this st...
We summarize the economic importance, biology, and management of soft scales, focusing on pests of agricultural, horticultural, and silvicultural crops in outdoor production systems and urban landscapes. We also provide summaries on voltinism, crawler emergence timing, and predictive models for crawler emergence to assist in developing soft scale management programs. Phloem-feeding soft scale p...
abstract the cowpea weevil, callosobruchus maculatus is the one of the most destructive pests of the dried seeds including cowpea, chickpea, lentil, mung bean and broad bean. in the last few decades, the use of environmental friendly insecticides, particularly plant-based compounds, has attracted attention of many researchers. the objective of the present work was to evaluate the fumigant toxic...
Background and Aim: In order to providing healthy food and improve food security, it is vital to preserve and protect agricultural products from pest's damage during storage. This is especially crucial for strategic products such as grains and cereals. Inefficient management in this subject would lead to the loss of stored food and will make the country's economic dependence on the other. In pa...
in this paper we consider contact cr-warped product submanifolds of the type $m = n_ttimes_f n_perp$, of a nearly kenmotsu generalized sasakian space form $bar m(f_1, f_2, f_3)$ and by use of hopf's lemma we show that $m$ is simply contact cr-product under certain condition. finally, we establish a sharp inequality for squared norm of the second fundamental form and equality case i...
