Pests Which Are More Prone to Attack Roses

Aphids

There are various types of Aphids that feed on roses. Aphids have sharp mouthparts that they use it for piercing and sucking the plant’s sap. Although smaller population of Aphids doesn’t cause much damage to roses, their high reproduction rate allows them to quickly reach the numbers that are sufficient to harm the roses.

Aphids rose

Roses suffer from a stunted growth due to their feeding characteristics. If the infestation is heavy enough, it could also reduce the bloom concentration of the roses. Moreover, Aphids excrete honeydew when they feed on roses. Honeydew further attracts ants and wasps where it promotes the growth of fungi on leaves of the roses.

Aphids can easily be controlled by spraying a strong stream of water on roses or spraying insecticide on the leaves. However, they are very difficult to exterminate since their reproduction rate is very high.

Beetles

Beetles are known to feed on flower buds of the roses. It is also possible for them to feed on leaves. They are very stealthy and feed only during night time. This makes it difficult for the gardener to spot them.

Beetles roses

Beetles have a short lifespan of around 30 days. They have strong mouthparts which are used to feed on various species of plants. When a plant is fed by beetles, they cause torn sides and holes on petals while leaves of the plant are skeletonized. Sometimes the entire flower is eaten by the beetles.

They can easily be exterminated by handpicking and placing them in insecticide solutions. 

Mites

Mites are extremely small in size and they are difficult to be seen without a magnifying glass. They also have piercing mouth parts that they use to feed on plant sap. After they feed on leaves, a white speckling takes place on the upper surface. Fine webbing also gradually develops on the leaves and further harm causes them to fall. Furthermore, dust particles are accumulated due to webbing on leaves.

Spraying water and applying insecticidal soap on the lower portion of the leaves is recommended for preventing against mites.

Rose Scale

Rose scale insects are highly resilient to most of the insecticides. They tend to secrete a waxy covering which protects them from several insecticides. Furthermore, the waxy covering also helps them for camouflaging.

They are found on rose canes mostly where they use their mouthparts to feed on plant sap. As the infestation becomes heavier, twig dieback occurs in rose canes.

Rose Scale

Rose scales are naturally controlled by ladybugs and parasitic wasps. They can also be removed from the leaves by hands. However, insecticides are not recommended for prevention as it causes harm to their enemies. 

Environmental Consequences associated with Insecticides

Insecticides have played a vital role in preventing our plants and crops from vector-borne diseases. Since the date they were synthesized, they have been serving mankind with their battle against diseases. However, they do come with some consequences despite the fact that they are so efficient in protecting us. As a result, pesticides are chemicals like any other chemical substance and they do pose a threat to our environment when they are used in large quantities.

Insecticides cause toxicity in food, water, air and even in the soil. They are also responsible for killing non-target organisms which are considered beneficial for our environment. Furthermore, pests have developed resistance towards insecticides throughout the years. This causes more insecticides use on plants which leads to more pollution of our environment.

Insecticides are also responsible for interfering with food-chain by eliminating essential food sources. Around 72 million birds are killed every year due to the extensive use of insecticides.

Among the human being, children are more prone to the harmful effects of insecticide since they have a relatively weaker immune system compared to the adults. Exposure to insecticides can cause various harmful diseases. A harmful insecticide, which is known as DDT, was banned because of this reason. It was responsible for mutating somatic cells, which caused leukemia and breast cancer.

Although strict policies are being enforced about the use of insecticides, we have become so dependent on them. For this reason, it is not possible to stop their use completely. However, it is necessary to limit their use and also to improve their quality. As anything else, they may become toxic if they are used extensively.
