The invention relates to agricultural farming machinery, in particular to a bionic anti-drag subsoiler based on the contour curve of the second toe of the forefoot of a mole cricket. According to the bionic anti-drag subsoiler based on the contour curve of the second toe of the forefoot of the mole cricket, the bionic anti-drag subsoiler is designed through the contour curve of the second toe of the forefoot of the mole cricket, so that the tillage resistance of the subsoiler is reduced, and oil consumption of subsoiling operation is reduced. According to the technical scheme, the bionic anti-drag subsoiler based on the contour curve of the second toe of the forefoot of the mole cricket is characterized in that a bionic shovel handle comprises a shovel handle straight handle section and an arc-shaped shovel handle bionic section, wherein the upper end of the shovel handle bionic section is smoothly connected with the shovel handle straight handle section into a whole; the longitudinal section contour line of the soil contact side of the shovel handle bionic section is based on the inner contour line of the longitudinal section of the second toe of the forefoot of the mole cricket, and the longitudinal section contour line of the soil separation side of the shovel handle bionic section is based on the outer contour line of the longitudinal section of the second toe of the forefoot of the mole cricket; the left contour line and the right contour line of the bionic shovel point are based on the left contour line of the second toe of the forefoot of the mole cricket.

The present application relates to the technical field of bionic robot, and particularly relates to a bionic mole cricket micro crawling and excavating robot based on multi-mechanism cooperative driving. The bionic mole cricket micro crawling and excavating robot comprises a four-legged crawling mechanism for driving the whole robot to move on the ground, a steering mechanism for adjusting the moving direction of the four-legged crawling mechanism on the ground and a bionic excavating mechanism for excavating soil; the four-legged crawling mechanism comprises a body and four bionic legs located at the bottom of the body, each group of the bionic legs is provided with a leg lifting mechanism and a leg swinging mechanism for periodically driving the bionic legs to sequentially perform leg lifting and leg swinging actions respectively; a transmission mechanism is arranged in the body, and the transmission mechanism is used for simultaneously driving the leg lifting mechanism and the leg swinging mechanism of each group of the bionic legs. The crawling mechanism design driven by a single motor reduces the number of actuators, makes the robot structure more compact, and through the multi-mechanism cooperative driving design, the robot can simultaneously realize the functions of crawling, steering and excavating.

The invention discloses a field drip irrigation anti-bite system based on a high-density polyethylene (HDPE) pipe and pre-sowing soil synergistic treatment, relates to the technical field of agricultural irrigation and pest control, and aims to solve the problems of weak insect bite resistance, short medicament timeliness, high soil pollution risk and the like caused by a single protection means of an existing field drip irrigation pipe. The system comprises a high-strength HDPE drip irrigation pipe main body and a pre-sowing soil integrated treatment module, the HDPE pipe forms a physical protective barrier through a specific wall thickness (0.8-1.2 mm), an anti-impact modified formula (containing 8-10% of POE elastomer) and an outer wall spiral reinforcing rib; the pre-sowing soil treatment module forms a slow-release insect prevention belt for 1-3 months around a drip irrigation pipe through environment-friendly sophocarpidine granules (the effective components are larger than or equal to 3%), precise belt type pesticide application and rotary tillage mixing. Field tests show that the protection rate of underground pests (cutworms, grubs and mole crickets) is larger than or equal to 95%, the damage rate of drip irrigation pipes is smaller than or equal to 2%, matrine soil residues are smaller than or equal to 0.01 mg / kg, and the method is suitable for large-scale field planting of corn, cotton and the like.

Pesticidal compositions and methods of use are provided. An aqueous pesticidal suspension composition comprises indoxacarb, a dispersant, a surfactant, and water, wherein the dispersant and surfactant are present in amounts effective to maintain the indoxacarb as a stable suspension during storage. The composition may optionally include one or more formulation additives such as a thickener, preservative, antifreeze agent, or antifoaming agent. A suspension concentrate comprising higher levels of indoxacarb, dispersant, and surfactant is also provided and may be diluted prior to application. Methods of controlling pests are further disclosed, including applying an effective amount of an indoxacarb-containing composition to turfgrass or ornamental plants to control pests such as black cutworm larvae, tawny mole cricket, and Genista caterpillar. The compositions may be applied directly or as diluted spray solutions at selected application rates to provide effective pest control with acceptable plant safety.
