Donna, whiteflies can be a terrible challenge. I disagree that spraying them with water helps to control them. The eggs and nymphs, tucked away under the leaves, are pretty fixed in place. Do you have any horticultural oil on hand? There are some good summer weight products on the market. You could mix a little in a spray bottle and direct the mist to the underside of the leaves. Hort oils are considered acceptable for organic growers. Neem oil is very useful in that it works as an anti-feedant, as a growth regulator for those insects that feed on the plants, and also smothers the eggs and nymphs just like a plain hort oil. If I had a bad WF problem on my tomato, I'd use Neem.

Gem, there is a FAQ for whiteflies, however, I do believe it is of limited use in the treatment of whiteflies. The yellow sticky traps are more of an indicator that you have them instead of a cure. Ants are only there because they are attracted to honeydew that the whitefies are producing. Getting rid of the ants won't solve the problem either as they are only there because of the honeydew. They are not "harvested" like aphids. So what to do... To gain a further understanding of the problem, you have to know why whiteflies are tought to get rid of. Whiteflies have a short life cycle 6-8 days. In this time they live to procreate, they and their larvae suck out the juices out of your plants, and then add the sooty mold (from the honeydew) to further weaken the plants. You have to be persistent with them as no solution is easy. You have several easy non toxic choices. Right now since you have them, I would suggest you use start spraying them off every day, twice a day. You have to do this for at least 2 weeks before you start seeing some results. You could also augment this by using insecticidal soap or a hydrogen peroxide solution (3 parts water to 1 part peroxide + a little dishsoap so it can stick to the leaves better) also on a daily basis. Since the lifecycle of a whitefly is so short--by then they have laid eggs which will have hatched and produced more whiteflies--the cycle goes on. In their larvael stage, they are almost inductructible. You have to get them in their adult stage. By going after them for 2 weeks, you should be able to get rid of 3 generations of whiteflies. Once you notice that the population has decreased, you can use water a couple times a week to control the population. To control the population in the future, underplant plants sensitive to whiteflies like tomatoes, hibiscus, and others with plants that attract beneficial insects. This method is called companion planting (I attached a link). This includes such plants as marigolds, sweet allysum, and dill among others. These plants help attract beneificial insects such as lacewings whose larvae devour whiteflies and other pests by the hundreds. Other plants actually repel certain pests so you don't have to worry about them in the future. I prefer to let nature take care of the pest problem itself. It just takes a little planning beforehand and these problems will be taken care of for you. Beneficial insects and companion planting will do a great job in pest control if you give it a chance. Good Luck and HTH Here is a link that might be useful: Companion Planting

Some type of aphid perhaps? If they are, check out this link I found a couple years ago...it's the most natural way to deal with them and when the aphids are all gone, they'll be gone as well... Here is a link that might be useful: Ladybugs Shipped Direct

It looks like your tomato plants are sun-scorched. Sometimes container-grown plants will not be able to get water to their leaves in time on a hot day even if the soil is damp. That's especially the case if the soil is constantly wet, which prevents deep rooting, and then it suddenly gets more heat or drier air than it's used to. Ironically, on a dry day when the humidity is lower you personally feel cooler and don't notice the heat as much, because your sweat is evaporating keeping you cool. You don't notice that it's the exact same day that your plants are having the hardest time in the heat. It's strange that this happened to some plants in your containers but not the others. I've had this happen to me before, with healthy-looking, fast-growing herbacious plants like petunias, nicotana, and basil. It seems to always happen in plants in containers. I speculate that the really sheltered lives they live while container-grown prevents their root systems from growing stronger, which would prevent a hot day from seriously damaging them. You could try getting a bucket or tray of water and putting the entire container in the tray, and making sure there is always 1-2 inches of water in it. If the water is coming from the bottom it will encourage all your tomato plants to grow deeper roots all the way to the base of the pot. As for the bugs... tough to advise but perhaps it would help to "expose" your plants to the rest of the garden better, by moving them closer to some other plants, and hope that beneficial insects like ladybugs and spiders will get on them and eat the bad bugs. I think there are a lot of cases in which isolated plants become infested by rapidly-multiplying insects like aphids, white flies, mites, etc... because there isn't enough contact with the rest of the garden's ecosystem.
