Cucumber Beetles Aplenty, Cucumber Beetles Galore!

While many other astrological and lunar calendars were marked by the presence of one animal or another, 2023 was, for me, "The year of the Cucumber Beetle".

 

 

 

 

 

Never have I experienced cucumber beetles in such numbers in my life. I spent well over 50 hours combating them in order to realize a harvest of some of the varieties that I was growing. Two-thirds of the varieties that I was growing were so profoundly impacted by them that they produced a drastically decreased harvest that was not worth sharing with others.

 

 

 

Altogether, the only good thing about the cucumber beetles was when I was done with them. The end of the season provided me with much needed relief. Given the amount of work I put into these plots, I am hesitant to attempt growing in those plots again.

My Experience with Cucumber Beetle Traps and Lures

In a desperate attempt to control the onslaught of cucumber beetles infesting my two Suisun Valley plots, I purchased some yellow sticky traps and pheromone lures for cucumber beetles. Let’s just say that they did not produce the desired results.

Instead of mostly killing off cucumber beetles the traps mostly caught bees and butterflies. I even checked to make sure that I had purchased the correct product for the species of beetle I was trying to remediate. The results were was pretty sad. Either the beetles have undergone adaptations that make it so that they don’t care for the traps and lures or the traps and lures never worked to begin with.

 

 

In any case, I returned the remainder of the traps and lures to the company that I purchased them from and hope that I will never purchase another product that will unintentionally injure or kill off my beneficial insect friends.

The Conquered Conqueror Cucumber

I received seeds of a parthenocarpic cucumber variety from the Seed Saver’s Exchange collection by the name of Conqueror. It was supposed to be an English variety that was parthenocarpic. English cucumber varieties are prized for being good to grow in greenhouses and parthenocarpic varieties would be ideal in those conditions because the vines produce fruit without pollination.

 

 

 

Unfortunately, something about the climatic conditions of 2023 along with a nearby pumpkin patch that overwintered cucumber beetle pupae all combined to make the situation for the Conqueror cucumber harvest dismal at best.

 

 

 

Every week I was fighting the cucumber beetles. I even purchased sticky traps that did not work and pheromones that didn’t work either. In the end, the endeavor was a nearly complete loss. I did manage to collect seed from one or two fruit, but the amount and quality of seed was much less than I would have anticipated in the number of plants that I was growing.

 

 

 

 

 

 

 

So, I will likely try growing the Conqueror Cucumber again. Hopefully this next time, they will at least be given a fighting chance.

The Rise and Fall of Tomatoes

2021 was not a very good tomato year for me. To date, that would make over half of my years as a gardener now. Honestly – some people have a gift for growing tomatoes while others, like myself, experience every kind of pest, pathogen and persistent pressure that promotes pitiful production. This year it was leaf curl, courtesy of some menacing whiteflies. 

 

 

 

 

 

 

 

 

 

While I had some some beautiful Taxi tomatoes that got taken out by the whiteflies, but I had some Ace 55 plants that took over. The Ace 55s were okay, but something kept making holes in them just as they would begin to ripen. My daughter also brought by a hybrid cherry tomato plant, which kind of did its own thing.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 We gardeners tend to be an optimistic lot, so – here’s to next season!

Some Thoughts about Integrated Pest Management

With all the posts about "good" and "bad" bugs, I really wanted to mention something. Just as plant roots suffer without healthy bacteria (those of you with clorinated pools near your garden know what I am talking about) I believe that my garden suffers without some amount of insect life. Specifically, what I am referring to is the lowly aphid.

 

 

 

 

 

Though a gardener may prefer to have no aphids at all, I believe that having a mild number of aphids on my plants is really good. Why? Because aphids are the foundation insect for many of the beneficial insects I appreciate in my garden. Ladybugs, lace wings, hoverflies, parasitic wasps, other wasps, assassin bugs, mantids, spiders, etc.

 

 

Syrphid Fly larvae eat aphids

 

 

 

 

Why do I love these beneficial insects so much? Because they do the majority of the work to take care of pest problems before they get out of control. Though some of these predatory insects only eat aphids, the majority of them consume other insect pests as well. They reduce the amount of work I have to do to maintain my garden and are thus a net positive.

 

 

Ladybird beetle larvae love aphids too

 

 

 

 

 

While I do work to reduce aphid populations before they really damage any one plant, I believe that using an Integrated Pest Management approach helps to keep garden pests in perspective. Instead of fighting my gardening problems, I much prefer to let nature to take care of some of my pests (excluding cucumber beetles) before I really need to.

Spider Mites

Sometime this last year some pest control salesmen came to my door to try to get us to pay their company to spray the bugs in and around our home. One of the salesmen mentioned all the spider webs. Soon after they left I experienced one of those moments when I leave the conversation only to realize what the perfect response would have been. 

The real reason why I love spiders is all about pest control. These helpful arachnids eat mosquitoes, flies and fruit flies. They keep all the other critters that cause disease away from my family and I. Thank you spiders!

As much as I like spiders around me property there are however, another type of web-weaving arachnid that I have zero tolerance for. These little red critters are the one of the vegetable vampires of the garden. Just when you thought your garden was safe, along come Spider Mites!

This last fall, I was visiting one of the schools that I work at and noticed a very sad-looking tomato plant. In fact, it looked pretty much dead. What's more, the tomatoes looked like something had been sucking there juices. In fact, something (or some things) had. The somethings were spider mites.

Spider mites require diligence and a keen eye to control. They tend to like specific plants, but can quickly get out of control if not identified and eradicated. I'm sure that they fill some niche in their native environment, though I work pretty hard to ensure that my garden does not welcome these 8-legged pests.

Coming back to the subject of spider mites, the reason why they are so bad is because they suck the juices out of whatever plant they are making their home. Their size can often make them difficult to spot and they multiply quickly. This is the reason why a gardener should eradicate these pests on sight. There are a number of ways a gardener can do this, but one of the most humane ways seems to be either some kind of insecticidal oil, soap or a good spray of water.

While I was at it, I decided to take a quick little video. Though my phone's camera is not the best, it should give you a good idea of what to look for.
