The present invention utilizes fungal spore mass or hyphal fragments in burlap bags or sacks filled with biodegradable materials. The fungi may include saprophytic fungi, including gourmet and medicinal mushrooms, mycorrhizal fungi, entomopathogenic fungi, parasitic fungi and fungi imperfecti. The fungi function as keystone species, delivering benefits to both the microsphere and biosphere. Such fungal delivery systems are useful for purposes including ecological rehabilitation and restoration, preservation and improvement of habitats, bioremediation of toxic wastes and polluted sites, filtration of agricultural, mine and urban runoff, improvement of agricultural yields and control of biological organisms.

The present invention utilizes the pre-sporulation (preconidial) mycelial stage of entomopathogenic fungi as insect attractants and / or pathogens. The fungus can be cultivated on grain, wood, agricultural wastes or other cellulosic material, attracting the insect and optionally introducing insect-specific pathogenic fungi. More than one fungus and substrate can be used in combination. The matrix of preconidial fungi can optionally be dried, freeze-dried, cooled and / or pelletized and packaged and reactivated for use as an effective insect attractant and / or biopesticide. Attractant extracts of the preconidial entomopathogenic mycelium are disclosed.

The present invention utilizes extracts of the pre-sporulation (preconidial) mycelial stage of entomopathogenic fungi as insect and arthropod attractants and / or pathogens and can be employed to limit the zoonotic and plant diseases they transmit. The fungus can be cultivated on grain, wood, agricultural wastes or other cellulosic material and extracts can be made thereof. More than one fungus and substrate can be used in combination with one or more antimicrobial, antiprotozoal, antiviral, or genetically modified agents that result in reduced spread of contagions and lessens the damage they inflict on animals and plants.

Microsclerotia of entomopathogenic fungi, including Metarhizium species, Beauveria species, and Lecanicillium species, may be produced. These microsclerotia are effective for the control of a wide variety of insect pests, particularly soil-dwelling insect pests.

The invention relates to a new fungicide product for the biological control of phytopathogenic fungi, which contains a new isolate of Bacillus velezensis strain AH2, deposited in the Spanish Type Culture Collection (CECT) as CECT-7221, which has a high antagonist activity against this type of pathogen, as well as the property of stimulating plant growth by different mechanisms. The invention also relates to a liquid formulation which has good stability at ambient temperature and is effective in the treatment of diseases caused by phytopathogenic fungi and for the stimulation of plant growth.

Strain of entomopathogenic fungus Isaria fumosorosea CCM 8367 (CCEFO.011.PFR) deposited in collection CCM (Czech Collection of Microorganisms) in Brno, applicable for biological control of substrates infested by insect and mite pests. Infested woods, plants, etc. are treated with blastospores or conidiospores of this strain.

The invention provides an entomopathogenic fungi transgenic strain which contains a homologous or heterologous acidic trehalase constitutive exogenous gene. The preparation method of the entomopathogenic fungi transgenic strain comprises the following steps: firstly building an acidic trehalase full-length cDNA gene constitutive expression vector; establishing a submerged conidia transformation system; and finally selectively screening to obtain the entomopathogenic fungi transgenic strain. The invention also provides application of Entomopathogenic fungi acidic trehalase transgenic strain in preparing fungal pesticide. The entomopathogenic fungi transgenic strain has high efficiency of expressing trehalase; and the preparation method has the advantages of easy operation, good repeatability and good reproducibility. The entomopathogenic fungi transgenic strain can be applied to preparing the fungal pesticide. When the fungal pesticide acts on insects, through the overexpression of the acidic trehalase gene via the transgenic strain, the activity of acidic trehalase in an insect host is improved, utilization of the trehalase is accelerated and growth of entomopathogenic fungi in the insect host is promoted, thus effectively improving the insecticidal activity of the fungal pesticide such as metarhizium anisopliae, beauveria bassiana and the like.

The invention relates to antimicrobial peptide and application thereof, and aims to provide a defensin gene of antimicrobial peptide of bemisia tabaci (Gennadius), the antimicrobial peptide encoded by the defensin gene and a preparation method for the defensin gene. A nucleotide sequence of the gene of the antimicrobial peptide is shown as SEQ ID NO.1; and an amino acid of the antimicrobial peptide is shown as SEQ ID NO.2. A protease Xa factor is introduced into an expression vector, so that recombinant fusion protein can be effectively digested, and defensin polypeptide is obtained through rapid separation in an ultrafiltration mode according to the magnitude of protein molecules; the whole process is quick and simple; and the obtained antimicrobial peptide has antifungal activity, and can remarkably inhibit the growth of entomopathogenic fungi such as Beauveria bassiana, Metarhizium anisopliae, Botrytis cinerea and the like.

Disclosed herein are pest controlling compositions comprising entomopathogenic fungi which are horizontally transmissible across pest populations and control target pests at various life stages. Further disclosed are methods of using such compositions for controlling pests, including, bed bugs and other invasive parasitic pests.
