  • Adult locusts arrived in the area in March. Scientists say they likely originated in Sudan and crossed from Egypt’s Sinai Peninsula into Israel. Then they mated and laid billions of eggs in the sand which are now hatching.
  • PCA data show the 15 barangays have 702,956 coconut trees and 5,975 of these are infested with the scale insect. The data also show the pest also attacked 1,170 ornamental plants, 382 lanzones trees, and 21 mango trees.
  • In Libon town in Albay alone, the infestation had affected some 90 hectares of rice fields, prompting local authorities to ask the national government for rat poison.
  • Deer have an appetite for saplings, which puts the forest in danger of becoming pastureland because overpopulated deer consume young trees. Deer grazing promotes the spread of ferns, which block sunlight from other plants, thereby hindering growth in the forest. Overpopulation is a vicious cycle for the ecosystem as the food chain, waterways and land are affected. Animal overpopulation threatens to change the entire make-up of an ecosystem.
  • Bubonic plague is mainly caused by fleas on small rodents and is one of three types of bacterial infections caused by Yersinia pestis a type of bacteria. Without treatment, the bubonic plague kills infected humans within 4 days
  • Seminar on Natural Disaster: Pestilence

    2. 2. Natural Disasters Natural disasters are extreme, sudden events caused by environmental factors that injure people and damage property. Earthquakes, windstorms, floods, and disease all strike anywhere on earth, often without warning. As examples, we've chosen disasters that have occurred around the world throughout history. Included Pestilence in the types of natural disasters
    3. 3. Pestilence All the men who set their faces to go to Egypt to live there shall die by the sword, by famine, and by pestilence. They shall have no remnant or survivor from the disaster that I will bring upon them.
    4. 4. Definition of Pestilence Pestilence means a deadly and overwhelming disease that affects an entire community. The Black Plague, a disease that killed over thirty percent of Europe's population, was certainly a pestilence. A disease that causes widespread crop damage or animal deaths can also be called a pestilence.
    5. 5. Definition of Pestilence The occurrence of one or more pest species in an area or location where their numbers and impact are currently or potentially at intolerable levels. A sudden increase in destructiveness or population numbers of a pest species in a given area
    6. 6. Examples of Pestilence
    7. 7. Locust Pestilence in Israel By Dave Copeland, Cameraman, NBC News  Huge swarms of the newly hatched critters have begun marching across the sand, devouring everything in their path. Israel’s Agriculture Ministry has deployed pickup trucks, planes and helicopters to spray pesticides on the locusts before they can inflict more damage. Experts estimate that a swarm of 30 million locusts will cause severe crop damage.
    8. 8. Locust Pestilence in Israel Teams of exterminators are working from sunrise to sunset, spraying the millions of young locusts as they move across the ground.
    9. 9. Examples of Pestilence
    10. 10. Insect Infestation threatens coconut Industry in Isabela City, Basilan By Rene V. Carbayas Tuesday 13th of August 2013 Scale insect (Aspidiotus Destructor Signoret), a soft-bodied 5mm long fluid-feeding insect is invading the coconut plants and other palm and fruit with 15 barangays affected by the pests. Hardest hit was Barangay Lanote with 2,519 coconut trees affected, followed by Maligue, Cabunbata, and Lumbang.
    11. 11. Insect Infestation threatens coconut Industry in Isabela City, Basilan there are many reasons why an outbreak of coconut scale insect occurred, and one of them is bad agricultural practices such as overuse or misuse of pesticides, particularly on the vegetables and fruit trees planted under coconut plants. “Pesticides also kill natural enemies and without them, insect pests are free to multiply without control,” he said.
    12. 12. Examples of Pestilence
    13. 13. Examples of Pestilence
    14. 14. Pestilence in Bicol prompts P1 reward for every dead rat's tail January 24, 2009 Rat pestilence in the rice fields in Albay in the Bicol Region has prompted local authorities to offer reward of P1 for every tail that comes from a dead rat The project, launched by the town government, is called "Bawat Buntot Piso Project" (A Peso for Every Tail Projects).
    15. 15. Effects of Pestilence Wandering the innate survival instincts of pests/ animals cause them to wander into unnatural places in search of food. The outcome is, animals are killed because of property damage and human injury.
    16. 16. Effects of Pestilence Damaged Ecosystems animals can wreck the ecosystem and surrounding landscape. The overpopulation of deer throughout areas of the United States is destroying the forest and hindering the diversity of tree species
    17. 17. Effects of Pestilence Lack of Food Pestilence damages crops and properties farmers cannot produce sufficient foods and other resources
    18. 18. Effects of Pestilence Disease Outbreak Pests can be a vector of bacteria, fungi and viruses that can cause diseases Uncontrollable spread of disease can cause the epidemics to humans Bubonic Plague
    19. 19. Pestilence Control provide a list of experts available for advice, including regional experts lists of insecticides and rodenticides that are readily available in appropriate formulations Using bait and fumigation Community Extermination Projects
    20. 20. Conclusion Pestilence is considered one of the natural disasters which cannot be prevent. Examples are locust, bees, dragonflies and other insects infestation; overpopulation of wild animals and plague of rodents. This phenomenon damages properties and crops which may cause lack of food and resources. It can also bring epidemics in humans. Pestilence control such as extermination projects, fumigation and bait must be done once occurred to avoid further spread.
