The authors summarized the significant achievements of Chinese grain storage (storage facility, storage technology), especially in basic theory research (survey of stored grain insect fauna, insect biology and ecology study, insect species taxelogy, insect resistance, mite, mi croorganism, mycotoxin, grain qality) and applied technology research (insect control tech nology, mould control technology, storage technology) in recent 50 years from historical ret rospect, science and research advance and technology.
This paper gives a concise introduction of insect-plant relationships, the recent development on the investigations of botanical insecticides, the chemistry of plant resistance to insects in relation to the breeding of resistant varieties, and the active defense of plants against insect attack in relation to insect control.
In this paper, the key techniques for peach cultivation in greenhouse like greenhouse build-up, choice of peach variety, planting, temperature regulation, flower and fruit management, disease and insect control, tree shaping, etc, are introduced.
The research situation of biological characteristics, cultivation technique, disease and insect control of Tremella fuciformis was reviewed, while the problems existed in genetics, breeding and strain preservation of T. fuciformis in China were also discussed in this paper. It would provide the basis for the further development and utilization of T.
On the basis of referring to the relative datas and summarizing seedling culture experiences,Photinia X clonal cutting seedling culture technology was summarized from the aspects of seedling nursery site selection and planning,scion-plucking nursery building and management,cutting technology,seedling transplantation and disease and insect control,etc. ,which provided the references for Photinia X seedling large-scale production.
When applied at 1200 ml/ha during peak activity of 2-instar larvae, trichlorfon plus fipronil provided 90.2% and 94.1% insect control 3 and 7 d after application, respectively, while leaf protection efficacy was 82.0% and 87.7%, respectively. These results were better than those provided by chlorpyrifos plus triazophos 30% EC at 1050 ml/ha and by triazophos 40% EC at 1200 ml/ha.
Experiments demonstrated that the raising of loaches and eels in mixture yielded more significant effect with the insect control rate and yield increase rate being 83%～99% and 12.7%, respectively,than the raising of loaches or eels alone did being 66%～90% or 59%～85% and 7.6% or 2.3%, respectively.
Site-specific Approaches to Cotton Insect Control.
We suggest that the receptor for the active chemical (s) (sex peptide?) would be an excellent target for biorational insect control by sterilization.
The potential of avocadofurans in insect control is discussed.
At present, practical application of several prospective structures for insect control is under investigation.
The levels of pheromone exposure required to produce significant adaptation were, however, found to be much higher than could be expected under conditions of release of synthetic pheromone for insect control through mating disruption.
