Whitebacked plant- hopper

The White-backed Plant Hopper, scientifically known as Sogatella furcifera, is a small insect that belongs to the family Delphacidae. It is a notorious pest of rice crops, causing significant damage to rice plants. Here is a detailed description of the White-backed Plant Hopper:

Appearance:

• The adult White-backed Plant Hopper is a tiny insect, usually measuring about 3-4 millimeters in length.
• It gets its common name from the characteristic white V-shaped marking or "white back" on its wings, which is easily noticeable when it is at rest.
• The overall coloration of the insect can vary, but it is generally brown or tan, with transparent wings.
• Nymphs (young stages) are wingless and tend to be pale green or yellowish.

Life Cycle:

• The White-backed Plant Hopper undergoes a life cycle with three primary stages: egg, nymph, and adult.
• Female plant hoppers lay their eggs on the stems and leaves of rice plants and other suitable host plants.
• Nymphs hatch from the eggs and undergo several molts as they develop into adults.
• Adults can reproduce rapidly, and multiple generations can occur within a single growing season, particularly in favorable conditions.

Damage and Impact:

• White-backed Plant Hoppers feed on rice plants by piercing plant tissues with their needle-like mouthparts and extracting plant sap.
• Feeding by large populations of these insects can cause "hopper burn," characterized by yellowing, wilting, and drying of rice leaves and stems.
• They are also known to transmit rice grassy stunt virus and rice ragged stunt virus, both of which can cause further harm to rice crops.
• Severe infestations of White-backed Plant Hoppers can result in substantial yield losses, which can have serious economic and food security implications in rice-dependent regions.

Control:

• Managing infestations of White-backed Plant Hoppers often requires a combination of cultural, biological, and chemical control methods.
• Cultural practices may include using rice varieties that are less susceptible to infestation, adjusting planting times, and maintaining proper water management in rice fields.
• Biological control may involve the use of natural predators, parasitoids, and entomopathogenic fungi that target these plant hoppers.
• Chemical control using insecticides is sometimes necessary but should be applied judiciously to minimize environmental impact and prevent the development of insecticide resistance.

The White-backed Plant Hopper is a significant pest in rice cultivation, particularly in regions where rice is a staple crop. Effective management strategies are essential to mitigate its impact and protect rice yields and food security in affected areas.
