A method for mosquito control is provided in the form of mosquito larvicide carrying insects which can be introduced in a mosquito population to thereby control the mosquito population. The larvicide carrier insects may include artificially generated adult insect carriers of a mosquito larvicide in which the mosquito larvicide has minimal impact on the adult insect carrier and which mosquito larvicide affects juvenile mosquito survival or interferes with metamorphosis of juvenile mosquitoes to adulthood. The larvicide carrier insects may be either male or female and may include mosquitoes and non-mosquito insects.

Surfactant compositions comprising an alkoxylate, a sulfate, or ether sulfate of a C.sub.10-C.sub.12 monounsaturated alcohol are disclosed. The alkoxylate, sulfate, or ether sulfate may derive from undecylenic acid or undecylenic alcohol. Compared with their saturated analogs, the monounsaturated alkoxylates, sulfates, and ether sulfates are less irritating, making them valuable for personal care, laundry, cleaners, and other household applications. Microscopy studies show that the alkoxylates, sulfates, and ether sulfates have favorable phase behavior over a wide range of actives levels, expanding opportunities for products with greater compaction. When combined with cationic surfactants, the alkoxylates, sulfates, and ether sulfates exhibit synergy, and they have improved solubility compared with their saturated analogs. The surfactants find value for the personal care, laundry and cleaning, emulsion polymerization, agricultural products, oilfield applications, and specialty foams industries.

Microbial compositions for application to plants, plant parts and plant seeds are provided for improvement of plant yield and/or other beneficial plant traits. Methods of making and applying microbial compositions or formulations to plants, plant parts or plant seeds or to growth media are further provided to increase or improve plant yield and/or other beneficial plant traits.

Insecticide dispensing devices and methods of the present technology provide for the prolonged release of insecticide for the eradication of insect populations. Insecticide dispensing devices include an attractive toxic sugar bait, and have a housing configured with at least one aperture to allow a gaseous compound to exit the internal cavity and sized to allow entry of a target insect into the internal cavity. Methods of insecticide dispensing include activating the attractive toxic sugar bait in the device, and placing the activated device in an area where insects are present.

Methods of synthesizing Bi.sub.2S.sub.3—CdS particles in the form of spheres as well as properties of these Bi.sub.2S.sub.3—CdS particles are described. Methods of photocatalytic degradation of organic pollutants employing these Bi.sub.2S.sub.3—CdS particles and methods of preventing or reducing microbial growth on a surface by applying these Bi.sub.2S.sub.3—CdS particles in the form of a solution or an antimicrobial product onto the surface are also specified.

Provided is a pink bollworm control method that controls pink bollworms by using a mating disruption method to disturb the mating of the pink bollworms. The method including at least: a step in which cotton seedlings are planted in a field 21-41 days after the appearance of adult pink bollworms if said adult pink bollworms are a first generation, or 1-21 days after the appearance of adult pink bollworms if said adult pink bollworms are a second or later generation; and a step in which a controlled-released sexual pheromone formulation including at least Z,Z/Z,E-7,11-hexadecadienyl acetate, which is a pink bollworm sexual pheromone substance, is placed in the field 2-15 days before the predicted adult appearance date for the next generation of adults of said pink bollworms, as derived from effective accumulated temperature, and the sexual pheromone substance in the controlled-release sexual pheromone formulation is released in the field.
