What are whiteflies and where do they come from?

Coming towards identifying these tiny creators you must be carious that what do whiteflies look like? It’s not hidden anyways that they belong to class Insecta and the most common occurring strains in the US climate are Bemisia argentifolii and Bemisia tabaci where B.argentifolii is also called silver leaf whitefly. Most of the species have a wingspan of 3 mm or even less, the body is 1 mm to 2 mm long. Some giant whiteflies have length up to 5 millimeters. They are small tiny insects when flying and tiny, flattened, oval scales when present undersides of the leaves as Nymphs where they are hardly noticed due to their hiding locations. B.argentifolii is usually causing the biggest destructions in the vegetables and fruit orchards while B. tabaci causes more destruction to the field crops such as Tobacco, Cotton, and Cereals. The best time to identify any of these strains is during their Nymph stage when they are present undersides of the leaves busy in sucking sap from the newly emerged leaves and tender shoots. They develop red eyespot upon changing their instar from Nymph to adult stages of their growth. The pupa of the Silver leaf whitefly looks rounded and dome and even pointed sometimes. The pupa has no filaments. They have several pairs of wax filaments arising from the top. Adults are generally white, as their name indicates, although the body of the Silver leaf is slightly more yellow. However, their color alone is not the basis for their identification but the difference in the angle of their wings to their body.

How do whiteflies damage plants?

Generally speaking, gardeners don’t like plants infested or damaged by whiteflies when they visit nurseries to buy plants as the quality of the plants deteriorate after they are infested with whiteflies and its not wise decision to bring already infested plants to your edible garden that may damage your existing plants. Whiteflies infest numerous garden plants by sticking them to the undersides of the leaves with the help of stylus that they insert into the epidermal leaf layer and suck the plant sap. Besides sucking sap they secrete sticky saliva on the surface of the leaves that creates an ideal media to attract sooty mold and many other fungi diseases. Whiteflies are also considered the carriers of tomato yellow leaf curl virus (TYLC) and Gemini Virus on Cotton causing (CLCV) which are hard to recover and diminishes thousands of acres of standing crops in the growing season.

What is the lifecycle of whiteflies?

Females often lay down eggs on the undersides of leaves, shoot curvatures and undersides of buds on the plant. Eggs numbers vary from 200 to 300 depending on the temperature and humidity in any particular area. A female may live up to 45 days that again depends on temperature. All life stages are passed on the same host plant except for the adult stage that migrates to neighboring plants. Eggs are in the form of tiny spindles in semi-circles. Hatching takes place in 8-10 days at 65°-75°F. Upon hatching, nymphs remain stick to the leaves for their feed until they pass other stages to become a flying adult. Depending on the temperatures, whiteflies may have 11 to 23 generations annually. It’s advisable to make necessary arrangements to control them when their populations exceed 5 adults per leaf or 10 Nymphs/leaf but it’s much better to keep them in control before they start flying to other plants to infest them.
Rapid multiplication of whiteflies does compel the serious gardeners to look into prevention and control techniques that are organic, natural and biological for a sustainable control without leaving residual effects on the edibles and their health as well. We will consider these techniques but our priority is how to control whiteflies organically.
Before we go into the further details look into the cultural practices that help prevent and know how to get rid of whiteflies naturally;

How to prevent whiteflies in your garden?

• Induce the culture of raising beneficial insects such as parasitic wasps, lacewings and ladybird beetle and create an environment to invite small predatory birds to live on these flies.
• Don’t bring infested plants to your garden area from the outside climate or nurseries.
• Hang yellow sticky traps and cards having a thin layer of petroleum jelly to control early invasions.

what do caterpillars eat?

Lepidoptera insects, in their caterpillar form, are voracious feeders and are one of the serious agricultural pests. Most species of moths in their caterpillar stage cause serious damage to fruits and agricultural produce. Therefore, a gardener must take measures to tackle this problem.

How many legs do caterpillars have?

Caterpillars of almost all insect species are herbivorous and nocturnal in nature, feeding primarily on leaves during the night. However, a few species are carnivorous while some feed on animal products such as wool, hooves, and horns, etc. Caterpillars can be easily identified by their eruciform body shapes. They most often have 3 pairs of true legs and five pairs of prolegs, making 16 legs in common. Some exceptional species of butterfly caterpillars, however, have no legs at all.

How long do Caterpillars live?

The caterpillar stage is not the final stage in the life cycle of Lepidoptera, therefore, the time span for which a Lepidoptera remains a caterpillar varies from species to species. The time for which some famous parasitic caterpillars do not transition to their pupal stage is given below.

• Inchworms – depending upon the amount of food available, inchworms may turn into their pupae in 2 to 4 weeks.
• Woolly bears – these caterpillars are found in the Arctic and hence, are adept at coping with such extreme temperatures. The life cycle of woolly bears can span up to 14 years due to the fact that they hibernate in extreme winters.
• Silkworms – they remain in their larval stage for 24 to 33 days.
• Monarch Caterpillars – in peak summer and warmer climates, the monarch caterpillar takes about 10 to 14 days to transition to the pupal form.
• Cabbage worms – they take almost 17 to 18 days to convert from their larval to the pupal stage after hatching.

Commonly found Garden Caterpillars

As most of the caterpillars are herbivorous in nature, they are naturally attracted to any greens which are grown in gardens. The adults will lay their eggs on their prioritized plants, which results in the appearance of caterpillars, which may be a cause of alarm for the gardener. Caterpillar identification can be a difficult task as many of them are excellent at camouflage and can remain hidden for long periods of time. In the case of extreme parasitic caterpillars or an infestation, it becomes necessary for the gardener to save their produce by taking appropriate measures. Most caterpillars appear green for camouflage in their habitat, so it may be laborious to identify the type of caterpillars. Some of the caterpillars, most commonly attracted to a garden, are listed below.

#1 Black Swallowtail (what do monarch caterpillars eat?)

Black Swallowtail caterpillar disguises as a Monarch caterpillar due to the reason that the Monarch caterpillar emits toxins from its body, which keep the predators away. Black Swallowtails mostly feast on Parsley, Carrots, and Dill. Therefore, if present in large numbers, they may damage these crops. Carrot greens are the most susceptible target for these caterpillars. Although they harm the crops, they are not harmful upon direct contact with the gardener.

#2 Woolly Bear(what do wooly bear caterpillars eat?)

Woolly bear caterpillars develop into Tiger Moth and are one of the most persistent caterpillars found in nature. Due to their habitat, they have bodies covered in thick fur. As they are found in the Arctic, where the temperatures in winter can be extreme, the caterpillars tend to hibernate, with their bodies producing natural antifreeze. Due to this ability, the life span of Woolly bears is about 10 to 14 years, mostly spent as a caterpillar. A whole lot of nutrition is required for the caterpillar to turn into its adult form, so, Woolly bears eat almost every green plant, from Oak trees to Dandelions. However, they seldom inflict serious damage upon the crops.

#3 Io Moth Caterpillar

These caterpillars belong to the group of Giant Silk Moths and are one of the few species of caterpillars, whose sting can cause serious infections in human beings. Their bodies are covered with spines which, upon contact, release toxins, resulting in rashes, allergies and in severe cases, death. Hence, it is advisory to take precautions while approaching such caterpillars. An infestation of these caterpillars in the garden can seriously damage it, as these caterpillars feed on a variety of garden plants, including Roses, Pin Cherry, Indigo, Oak, etc.

#4 Tomato Hornworm

Tomato hornworms are relatively huge caterpillars, found on many plants from the Solanaceae family. Although they have a horn on their tail, thus the name, Tomato hornworms are not dangerous to human beings and do not sting upon contact. However, as they feed on many beneficial plant species such as Tomato, Eggplant, Pepper, Tobacco, Moonflowers, and Potato, they are a serious parasite and can inflict great damage on the crops, eating up the entire plant.

#5 Genista Broom Moth Caterpillar

Although single-handedly, these caterpillars are not that harmful, as they have small-sized bodies and do not consume much on their own, they are considered a major threat to plants from Baptisia species, especially Blue False Indigo. The reason for this is that they are often in large numbers and attack the plants in the form of a small army, thus destroying the plant completely. Therefore, it is important to keep the plants safe from the swarms of these caterpillars.

#6 Copper Underwing Moth Caterpillar

They are a common caterpillar, found frequently in the gardens. These caterpillars are huge in size, and can often be mistaken for Tomato Hornworm caterpillars. Like Gensita Broom caterpillar, these caterpillars also appear in the form of large groups, hence the plants which are exposed to them can get seriously damaged. They are also considered as a dangerous parasite since they mainly attack fruit-bearing plants like Apple, Walnut, Grapes, Raspberry, Oak, Maple, Basswood, Hawthorn, etc.

#7 White-Lined Sphinx Moth

Belonging to the family of Hawkmoths, these caterpillars also attack the plants in swarms, inflicting major damage to the crops. In the same manner, as the Copper Underwing caterpillars, these caterpillars also target the edible crops in large numbers, hence pose a great threat to the product in a garden. The main targets of these caterpillars are Apple, Elm, Willow, Grape, Tomato, Fuchsia, and Primrose, etc.

#8 Cabbage White Caterpillar

One of the major species of caterpillars that are considered to be pests, Cabbage Whites can be found in quite an abundance in the wild as well as domestic greens. They are very common and are most probably present in almost all untended gardens. Since they have a soft green color, they are perfectly camouflaged with the cabbage leaves thus making them less visible to the eye. Cabbage worm poop can be seen on the leaves as black dots. As the name implies, Cabbage Whites can eat all cabbage related crops such as Green Cabbage, Red Cabbage, Brussels Sprouts, Bok Choy and Kale, etc.

#9 Cabbage Looper Moth Caterpillar

Another common type of agricultural pests is the Cabbage Looper caterpillars. Unlike their butterfly counterparts, Cabbage Loopers move around by arching their backs in a loop like a shape, thus attaining the name. it would not be wrong to say that the crops from cruciferous plants get inflicted by these caterpillars at least once during their growth. In a similar manner to the Cabbage Whites, the Loopers tend to attack Carnations, Nasturtium, Lettuce, Spinach, Beets, Parsley, Potatoes, and Tomatoes in addition to Cabbage, Cauliflower, Broccoli, and Brussels Sprouts. Proper measures must be taken to rid the garden from these parasites. The disposal of these caterpillars can also result in the stunted growth of the Cabbage, Brussel sprouts, and Broccoli flowers, etc.

#10 Inchworms (what do inchworms eat?)

In the same way such as some species of caterpillars explained above, Inchworms also tend to attack the garden in the form of hordes thus causing substantial damage to the vegetables or fruit trees growing there. They also exhibit a loop like motion by arching their backs, hence they are also referred to as Loopers. They usually feed on orchard trees such as Apples, Oak, Mulberry and Elm Trees, etc.

#11 Silkworms

Silkworms belong to the species of caterpillars which, although being parasitic, are used for cultivation of silk, used in the fabric industry.

Fungi of the genera Aspergillus penicillium is mainly responsible for mold growth. They are found almost everywhere especially in the soil since it’s their natural habitat. The organic debris or leaves or roots etc. are decomposed by molds to form humus. During their growth cycle on organic material, molds produce many spores that are spread through the air currents. These spores help in the reproduction of molds everywhere. Wherever there’s some decaying matter present, the chances of spores in the surrounding air are higher. These spores when inhaled can cause several respiratory problems. Moisture and warmness are the basic requirements for the growth of mold.
