Study Notes

Mango Seed Weevil

Order: Coleoptera
Family: Curculionidae
Scientific Name: Sternochetus frigidus (Olivier)
Economic Importance: Major pest affecting mango seed quality and fruit viability, leading to reduced yields and market value.
Damage: Adults bore into the seed, causing fruit drop and seed damage. Infestation leads to poor fruit quality and reduced seed viability.
Biology:
- Life Cycle: Egg → Larva → Pupa → Adult
- Eggs are laid inside the seed cavity, larvae feed on the seed, and pupae develop inside the seed before emerging as adults.
Control:
- Cultural Control: Harvest fruits as soon as they mature to reduce the risk of infestation.
- Chemical Control: Use insecticides targeted at weevil larvae and adults.
- Biological Control: Introduce natural predators such as parasitoid wasps.

Mango Fruit Fly

Order: Diptera
Family: Tephritidae
Scientific Name: Bactrocera dorsalis (Hendel)
Economic Importance: One of the most significant pests of mango, causing extensive fruit damage and economic losses due to reduced marketability.
Damage: Females lay eggs under the fruit skin, larvae feed on the fruit pulp, causing premature fruit drop and rotting.
Biology:
- Life Cycle: Egg → Larva → Pupa → Adult
- Eggs are deposited in the fruit, larvae feed on the pulp, and pupae develop in the soil before emerging as adults.
Control:
- Cultural Control: Implement sanitation practices, such as removing infested fruits and using fruit traps.
- Chemical Control: Apply insecticides and use baiting techniques.
- Biological Control: Release parasitoid flies such as Diachasmimorpha longicaudata.

Mango Hopper

Order: Hemiptera
Family: Cicadellidae
Scientific Names: Idioscopus niveoparsus (Lethierry)
Economic Importance: Affects mango trees by damaging leaves and panicles, leading to reduced fruit yield and quality.
Damage: Adults and nymphs suck sap from leaves and panicles, causing stippling, leaf drop, and panicle damage. Infestation can lead to poor fruit set and reduced yields.
Biology:
- Life Cycle: Egg → Nymph → Adult
- Eggs are laid on leaves and panicles, nymphs feed and grow on plant sap, and adults continue to feed and reproduce.

Mango Mealybug

Order: Hemiptera
Family: Pseudococcidae
Scientific Name: Drosicha mangiferae (Kuwana)
Economic Importance: Causes significant damage by feeding on sap and producing sooty mold, affecting fruit quality and overall tree health.
Damage: Mealybugs feed on plant sap, causing wilting, leaf drop, and sooty mold on honeydew, which reduces fruit quality.
Biology:
- Life Cycle: Egg → Nymph → Adult
- Eggs are laid in clusters on leaves and stems, nymphs develop into adults covered in waxy secretions.
Control:
- Cultural Control: Prune infested branches and improve plant hygiene.
- Chemical Control: Use insecticides and miticides.
- Biological Control: Introduce natural predators such as ladybugs and parasitic wasps.

Mango Scale Insect

Order: Hemiptera
Family: Diaspididae
Scientific Name: Aonidiella orientalis (Newstead)
Economic Importance: Affects mango trees by sucking sap, leading to sooty mold and reduced fruit quality and tree health.
Damage: Scales feed on sap, leading to sooty mold development on fruit and leaves, which weakens trees and reduces fruit quality.
Biology:
- Life Cycle: Egg → Nymph → Adult
- Eggs are laid on branches and leaves, nymphs settle and feed, and adults develop under a protective scale.
Control:
- Cultural Control: Regularly inspect and clean plants.
- Chemical Control: Apply systemic insecticides and scale-specific treatments.
- Biological Control: Utilize natural enemies such as predatory beetles and parasitic wasps.

Mango Thrips

Order: Thysanoptera
Family: Thripidae
Scientific Name: Scirtothrips mangiferae
Economic Importance: Damages fruit and flowers, leading to reduced fruit quality and yield.
Damage: Feeds on flower and fruit tissues, causing deformities, scarring, and reduced fruit quality.
Biology:
- Life Cycle: Egg → Nymph → Adult
- Eggs are laid in flower or fruit tissues, nymphs feed on plant tissues, and adults continue to reproduce.
Control:
- Cultural Control: Remove and dispose of infested plant parts.
- Chemical Control: Apply insecticides effective against thrips.
- Biological Control: Release predatory thrips and other natural enemies.

Mango Bark-Eating Caterpillar

Order: Lepidoptera
Family: Cossidae
Scientific Name: Indarbela tetraonis (Moore)
Economic Importance: Infests trunks and branches, causing structural damage and dieback, which reduces fruit production.
