Plants MCQs – Part 4

Correct Answer: Spreading fungal spores

Explanation: Pests, such as aphids and beetles, can play a significant role in the spread of plant diseases by transporting fungal spores from infected to healthy plants. As they feed on plant sap or tissue, they may inadvertently pick up pathogens, which they then deposit on new plants, facilitating the spread of diseases like powdery mildew and rust.

Correct Answer: Whitefly

Explanation: Whiteflies are notorious for transmitting the Tomato yellow leaf curl virus, affecting tomato plants and other crops. These small, sap-sucking insects feed on the underside of leaves and can spread the virus as they move from one plant to another, leading to significant crop losses if not controlled effectively.

Correct Answer: They can be pathogenic and cause root rot

Explanation: Some nematodes are pathogenic and can cause severe damage to plant roots, leading to root rot and other diseases. They feed on plant tissues, disrupting nutrient and water uptake, which weakens the plant and makes it more susceptible to other infections. Understanding nematodes’ role is crucial for effective disease management in crops.

Correct Answer: Thrips

Explanation: Thrips are tiny pests that can cause significant damage by feeding on plant tissues and weakening their defenses. As they puncture the leaves and stems to feed, they create openings that allow pathogens to enter, making plants more vulnerable to diseases. Managing thrip populations is essential for maintaining healthy plants.

Correct Answer: Stunted growth

Explanation: Insect infestations often lead to stunted growth in plants due to the loss of sap and nutrients as pests feed. Additionally, the stress caused by feeding can trigger hormonal changes that inhibit growth, making affected plants weaker and less capable of producing healthy foliage and flowers.

Correct Answer: Ladybug

Explanation: Ladybugs are beneficial insects that help control pest populations, including aphids and spider mites, which are known to transmit plant diseases. By feeding on these harmful pests, ladybugs help maintain plant health and reduce the likelihood of disease outbreaks, making them valuable allies in organic gardening.

Correct Answer: They can lead to yellowing leaves and reduced vigor

Explanation: Spider mites are notorious for causing damage to plants by sucking out plant juices, leading to yellowing leaves and reduced vigor. Their feeding can weaken plants, making them more susceptible to diseases and other pests. Effective management of spider mite populations is essential to maintain healthy plants.

Correct Answer: Regular monitoring and biological control methods

Explanation: Regular monitoring of plants for signs of insect infestations is crucial in managing plant diseases effectively. Implementing biological control methods, such as introducing beneficial insects or using natural predators, can significantly reduce pest populations and minimize the spread of diseases, promoting overall plant health.

Correct Answer: Codling moth

Explanation: The codling moth is a significant pest of fruit trees, particularly apples and pears. As larvae burrow into the fruit, they create entry points for pathogens, leading to fruit rot and other diseases. Effective management strategies, such as traps and natural predators, are essential to minimize damage and maintain fruit quality.

Correct Answer: They weaken plants by sucking sap and can transmit viruses

Explanation: Aphids weaken plants by feeding on their sap, leading to reduced vigor and overall health.
