ORGANIC CONTROL FOR BEETLES, CATERPILLARS, AND GRASSHOPPERS
These are hard-shelled insects with chewing mouthparts. Adults and larvae feed on leaves and fruits. Larvae (grub stage) of some like Japanese or cucumber beetles, feed on plant roots, which can kill the plant.
ORGANIC BEETLE CONTROL INCLUDES
Bacillus Thuringiensis - Bt (a naturally occurring bacterial disease of insects) will kill them in the larvae stage; Organic Neem Oil - a brown liquid with garlic odor - used as a fungicide/insecticide/miticide with a toxicity to fish and invertebrates. It is best used in the evening to protect beneficial insects; Intercropping and companion planting; Rotonone-pyrethrin sprays/powders (which also have a toxicity to fish and invertebrates, and should be used in the evening to protect beneficial insects); Handpicking off plants; covering the crops with floating row covers.
BLISTER BEETLE - Megetra
Sometimes called the water beetle. It is found on leaves, flowers, and plant foliage - indigenous to western NM and AZ.
For more information on this beetle, and its Navajo lore, go to Bug guide.net
COLORADO POTATO BEETLE
Found on the leaves of vegetables, especially eggplant, potato, and some flowers.
Found on leaves, flowers, and roots of many vegetables including the cucumber family
These are tiny hopping black beetles that chew holes in plant leaves, and can spread diseases such as early blight to potatoes or bacterial wilt to corn. Larvae feed on the plant roots. In the southwest after a rain during the hot summer months, we have seen puddles of them, a black mass huddling and moving with a wave like motion.
Adults feed on ornamental and edible crops, chewing leaf tissue between the veins leaving a lacy skeleton. Before they pupating, they are 1-inch-long, white, c-shaped grubs living in the soil and feeding on roots and they are often a problem in lawns.
MEXICAN BEAN BEETLE
These are related to ladybugs but are not beneficial. The adults have sixteen black spots on their back and the Larvae are fat, spiny yellow grubs 1/3 inch long. Both feed on foliage, leaving plant leaves a skeleton of veins. Adults overwinter on plant leaves, in late spring or early summer lay clusters of yellow eggs on the undersides of leaves, and there can be one to four generations a year depending on different climates.

ORGANIC CONTROLS INCLUDE
Bacillus Thuringiensis - a biological powder that can be applied at the caterpillar stage, Bt (a naturally occurring bacterial disease of insects) will kill them when they are very small; HAND PICKING and relocating a 1/4 mile away is a good way to control caterpillars. We put them in a gallon can and then take the dogs for a walk and deposit them elsewhere.
A big fat green caterpillar that can grow up to 5 inches long, and feeds on leaves and fruits of eggplants, tomatoes, peppers, and potatoes for about a month and then enter the soil to pupate.
Adults emerge as beautiful sphinx moths that are grayish-brown with orange spots on the body, a long proboscis, with a 4- to 5-inch wingspan. They are amazing and sound like hummingbirds. They overwinter in the soil as brown spindle-shaped pupae cases, and emerge in late spring to early summer feeding like hummingbirds on plant flowers and then laying greenish-yellow eggs on the undersides of leaves.
HARNESSED MOTH - Grammia figurata larva
That year we had a plethera of caterpillars caused by the lack of our usual September 5th frost. Below are a few photos of yet to be identified caterpillars we have seen. The first is a photo of a caterpillar eating the petals off a NM wildflower.

ORGANIC CONTROLS INCLUDE
Grasshoppers can be organically controlled most easily when they are about 3/4 of an inch long using a biological bran-based bait called Nolo Bait, Semaspore, or Grasshopper Spore. These are not harmful to animals, people, plants or other insects, but will kill, over time, most species of grasshoppers by infecting them with Nosema locustae, a parasitic protozoa. They spread the disease among themselves by eating other sick grasshoppers or by laying infected eggs. The disease will eventually spread throughout the entire population, but it may take a year or so. The organic products have a short shelf life, and are viable for 90 days after the label date. It is available from the links below.

Attracting Birds to Your Yard
Crickets and Grasshoppers belong to the order Orthoptera. There are more than 400 known species of grasshoppers in the Western United States, but only about two dozen are considered pest species capable of producing economic damage. Grasshoppers favor certain vegetable plants such as lettuce, carrots and onions. They tend to avoid other vegetables such as squash, peas and tomato leaves, so inter-cropping would help some. However, during years when grasshoppers are extremely abundant and food is scarce, they feed on almost all plants.
