mgpaquin According to this site, the tomato yellow leaf curl virus does not survive in soil. I'd do some more research to make sure that's what all the research says. I also found the site linked below that describes an odiferous "invention" to repel whiteflies using fermented eggshells and eggwhites as the ingredients. It sounds pretty smelly, if you know what rotten eggs smell like! Here's the process described in the link. I don't know if it could be reproduced by home gardeners or not, since the information given appears to comprise some sort of formula that someone wants to take commercial. I'm also not sure if you're supposed to spray the plants with the resulting smelly mess or water the soil with it. The author says the plants themselves begin to smell of sulfur and thereby whiteflies are repelled, so I concluded the soil around the plants should be watered with it. Yet, in another place the author mentions "placing" it on leaf surfaces. If the plants smell like sulfur, I suppose any fruit would taste like sulfur, and nobody wants tomatoes to taste like that, but who knows? Maybe one tomato plant in a container could be sacrificed as a test! ===== There are many parts of an egg including the albumen or egg white. Typically, the albumen accounts for about sixty-seven percent of an egg's weight. The albumen contains more than half of the egg's total protein, minerals and vitamins. The albumen contains protein, niacin, riboflavin, chlorine, magnesium, potassium, sodium and sulfur. The pest repellant is produced by fermenting eggshells with a portion of the albumen attached thereto. Fermentation is the chemical process that breaks down organic materials. The process is carried out by bacteria, molds and yeasts that are present in the air. It is believed that the fermentation process liberates sulfur from sulfates and sulfides present in the amino acids of the eggshells and albumen. A chemical analysis of chicken eggs was undertaken and the following results were yielded. One-hundred grams of fresh chicken eggs contains approximately 70.83 g of water, 12.14 g of protein and 11.15 g of lipids. Minerals present in the eggs were as follows: 56 mg of C, 2.09 mg of Fe, 12 mg of Mg, 180 mg of P, 130 mg of K, 138 mg of Na and 1.44 mg of Zn. Vitamins included in the fresh eggs were as follows 0.087 mg of Thiamin, 0.301 mg of Riboflavin, 0.062 mg of Niacin, 0.120 mg of B6, 1.547 mg of B12 and 520 IU of A. The chicken eggs also included amino acids in the approximate quantities: 0.820 g of Lysine, 0.392 g of Methionine, 0.289 g of Cystine, 0.596 g of Threonine, 0.759 g of Isoleucine and 0.686 g of Phenylalanine. Methionine and Cystine both include sulfur. Methionine is represented by the following structural formula. ##STR2## Cystine is represented by the following structural formula. ##STR3## Since the eggshells and albumen contain amino acids that comprise sulfur, sulfur dioxide is created during the fermentation process. Sulfur dioxide is a colorless gas with a distinctive odor. The sulfur dioxide contributes to repelling the pests as it is placed on the leaf surfaces of the plant. The plants also absorb the sulfur present in the mixture of eggshells and albumen and give off a sulfur smell that repels pests. Another important element in the pest repellent is sulfide. Sulfide is a chemical compound that contains sulfur and another element. All sulfides contain the sulfide ion, a single sulfur atom with an electrical charge of -2. Sulfide ions are present in some proteins which make up living things. Since eggs are high in proteins, sulfide is present in them. During the manufacturing process of the pest repellent sulfur from the sulfide is liberated by the fermentation process. The best contemplated process for producing the pest repellant, involves collecting eggshells with part of the albumen attached thereto. The eggshells are placed into a metal or plastic container with warm or hot water. Over a period of time, the water coupled with bacteria and other fermenting agents dissolve the eggshells and cause them to decompose and liquefy. The mixture of water, eggshells and albumen are allowed to ferment for a period of time. Typically, the mixture ferments for at least twelve days. Heat may be introduced into the curing time to increase the fermentation process and cause chemical bonds to be broken thereby more quickly liberating sulfur. Likewise, the mixture may be stirred occasionally to increase the fermentation process. Typically, the mixture is tested using a hydrogen sulfide test kit to determine whether it is ready to be applied to plants. The mixture is ready for use as a pest repellant when the hydrogen sulfide is present in at least an amount of 0.424 mg/I. The mixture is then strained to remove visible or non-liquid particles. Silt sized particles may remain in the mixture due to the calcium in the shells. Typically, the calcium carbonate of the egg shells does not breakdown entirely leaving silt sized particles which may be filtered from the mixture. In the preferred embodiment, the silt sized particles are left in the mixture and are applied at the base of the plant adding nutritional value to the mixture. The preferable ratios of chemical compounds in the mixture are 250 ml of H2 O to 24.3 g of CaCO3 to 1.060-5 g of H2 S. The following is the structural formula for the pest repellant. ##STR4## The following are examples of the effectiveness of the pest repellant mixture. EXAMPLE 1 A mixture of hydrogen sulfide and calcium suspended in water, as mentioned above, was applied to a poinsettia plant. The poinsettia plant was placed near a gardenia bush that was infested with white flies. The poinsettia plant was monitored and visually inspected bi-weekly for approximately five months during warm weather. Visual inspections of the poinsettia plant revealed no white flies, larvae or white fly eggs present on the leaves of the poinsettia plant. The plant remained healthy and productive with blossoms and leaves of deep color. EXAMPLE 2 A gardenia bush that was infested with white flies operated as a control. White flies were visibly present on the leave surface of the gardenia bush. A second gardenia bush was placed within approximately a foot of the control. The second gardenia bush was treated twice a month with a mixture containing 0.424 mg/l of H2 S as mentioned above. Visual inspections of the gardenia bushes were conducted over a four-month period of time. While the control remained infested with white flies, no white flies were present during the visual inspections on the second gardenia bush. Further, neither larvae nor white fly eggs were found on the underside surface of the leaf. The second gardenia bush remained healthy and did not become infested with the white flies. It is to be understood that the invention is not limited to the exact construction illustrated and described above, but that various changes and modifications may be made without departing from the spirit and the scope of the invention as defined in the following claims.

Hi Kamala : I have Ladybugs in my house also. In the spring they want to get out and go to the windows. I collect them, to put outside.Maybe they help with other insect pest problems. I don't think you would want them in your home, because they get into everything, even the computer.I gave 300 to my daughter to put in the garden. After a few weeks her girl friend said " don't see them anymore " My daughter told me later that her friend sprayed insecticide on all the plants. Why don't you try Google. Punch in"Aphids on Houseplants" See if you can find a spray.You are right about Garlic. It keeps away Vampires too. LOU

they use every means possible, including scent, and color, and also time of the year - most insects have a life [breeding] cycle that matches their preffered hosts occurance - ie: if you plant broccoli things later than usual you'll miss the first flush of cole family pests, and hopefully the plants will be big enuff to withstand later hatchings - some also tend to work at a certain level, and sometimes you can protect the plant simply by putting collars around the stem to keep the things like cutworms away, and a 2' "fence" of clear plastic along your carrot rows will keep out certain carrot root flies garlic, onion, cayenne and other strong scented things are good general protection, and growing those things, as well as things like marigolds, around your crops will help as well as the spraying - lotsa 'companion plant' possibilities, and using the traits of the bugs against them is part of what IPM is about, as well as organic growing Bill

Remember also, the young of most beneficials eat plants so, you cannot panic when beneficial wasp larva (rose slugs) appear. You'll have to wear blinders to avoid the damaged leaves caused by them. I respectfully, but firmly disagree with this particular information. The young of most beneficials also eat insects, and often it is only the eating that the young do that is beneficial at all. The adults of many beneficials, especially the little ones, either don't eat anything or eat nectar and pollen. That's why planting a variety of flowers, especially including small flowers such as sweet alyssum, dill, fennel, and yarrow, is useful. It attracts into your garden those little, tiny, just 2 millimeter long wasps you don't even see that are also looking to lay eggs on the aphids and rose slugs eating your flowers. The wasps that are beneficials . They're so tiny you don't generally even realize they're around. They can't even sting because they don't have stingers. . Sawfiles are in the same insect order as wasps (& so adult sawflies do bear a resemblance to wasps), but so also are bees and ants (which also bear a resemblance to wasps). Adult sawflies aren't predatory (& so aren't beneficial), and as immatures (such as rose slugs) they're plant eating pests.
