In biological control, the use of natural resources is a very open up potential research areas. This paper to Blattella germanica was tested insects. Through comparison of experimental separation pick bait vectors, insecticidal activity better large poisonous fungi and different processing products, then stop large poisonous fungi compound preparation the best ratio of selection, eventually must be consequences better Nianye type of Blattella germanica poison to kill poisonous fungi compound formula. Research results as follows: (1) through the eight guide bait agent selection, within 144H Blattella germanica on rat feed intake of food intake highest and stable, plus the compositionally diverse, low cost is to the bait vectors. Then through the selected 4 kinds of synergistic accessories, it is concluded that the consequences of 5%, brown sugar, suitable for, certainly eventually bait vectors for brown sugar 5% in the feed. In of Blattella germanica in captivity in the process in the invention and Blattella germanica on high density populations with strong resistance and water effect on cockroaches every stage of development, especially the main. (2) on the eve of the poisonous fungi of Blattella germanica poison to kill experiment, chapeau collected 19 kinds of germs stopped strains respectively and purified to create, is then applied stomach toxicity will be 19 poisonous species of wild seed entity and interior to create products of Blattella germanica to stop poison to kill the, that disability care spot goose anointed bacteria, scales handle Amanita Verna bacteria, leopard Amanita phalloides bacteria, striped goose anointed bacteria, scleroderma aurantium liquid makes insecticidal products have good effects. The above 5 kinds of germ separation stop five concentration gradient experiments, it showed that LCso was a disability care AMANITAE in 9 spot.

(3) in large poisonous fungi insecticide bait stability experiment, separation of bait disposal of low temperature and light, although fall after insecticidal experiments, heat poison bait storage stability is strong, and light stability is poor. (4) from single agent when selected toxic effect better residual spot goose anointed bacteria, scales handle Amanita Verna bacteria, leopard Amanita phalloides bacteria support three toadstool using interactive method for determination of stop, the best ratio selection, combination of virulence effect strong three formulation method of CO toxicity coefficient separation for disability care spot goose anointed bacteria / leopard Amanita phalloides bacteria 143. 98 "residual" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "". 09 "scale stem white poisonous goose cream bacteria / leopard spot poisonous goose cream bacteria 124. 55, expressed as a synergism.
