Metisa Plana
''Metisa plana'' (or "bagworm") is a moth of the family Psychidae (the bagworms) first described by Francis Walker (entomologist), Francis Walker in 1883. It is found in Sumatra, Malaysia and Sri Lanka. It is a major pest on ''Elaeis guineensis'', the African oil palm. Description The moth completes a mean life time of 90 days. After the female lays 200–300 yellowish eggs, a single egg mass can become about 140–210 neonates. The larva has a portable case which it carries around as it feeds. The first instar is about long. About an hour after emergence from the case, the larva starts to construct a small case around the posterior of their body using oil palm leaves. This constructed case is cone shaped. The case enlarges with each instar. At the fourth instar, the case is covered with loosely-attached large round or rectangular leaf pieces. At the sixth instar, the case surface is smooth and without loose leaf pieces. The larva turns whitish gray. It takes a mean of 71.5 days t ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Cyhalothrin
Cyhalothrin is the ISO common name for an organic compound that, in specific isomeric forms, is used as a pesticide. It is a pyrethroid, a class of synthetic insecticides that mimic the structure and properties of the naturally occurring insecticide pyrethrin which is present in the flowers of ''Chrysanthemum cinerariifolium''. Pyrethroids such as cyhalothrin are often preferred as an active ingredient in agricultural insecticides because they are more cost-effective and longer acting than natural pyrethrins. λ-and γ-cyhalothrin are now used to control insects and spider mites in crops including cotton, cereals, potatoes and vegetables. Structure and stereochemistry : Gamma-cyhalothrin and lambda-cyhalothrin are the active ingredients in the current commercial products based on cyhalothrin. Both are cyanohydrin esters of cis-3- Z)-2-chloro-3,3,3-trifluoropropenyl2,2-dimethylcyclopropanecarboxylic acid. All of the insecticidal activity is due to the proportion of absolute ster ...

Entomopathogenic Fungus
An entomopathogenic fungus is a fungus that can kill or seriously disable insects. Typical life cycle These fungi usually attach to the external body surface of insects in the form of microscopic spores (usually asexual, mitosporic spores also called conidia). Under the right conditions of temperature and (usually high) humidity, these spores germinate, grow as hyphae and colonize the insect's cuticle; which they bore through by way of enzymatic hydrolysis, reaching the insects' body cavity (hemocoel). Then, the fungal cells proliferate in the host body cavity, usually as walled hyphae or in the form of wall-less protoplasts (depending on the fungus involved). After some time the insect is usually killed (sometimes by fungal toxins), and new propagules (spores) are formed in or on the insect if environmental conditions are again right. High humidity is usually required for sporulation. Groups The entomopathogenic fungi include taxa from several of the main fungal groups and ...

Bacillus Thuringiensis
''Bacillus thuringiensis'' (or Bt) is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide. ''B. thuringiensis'' also occurs naturally in the gut of caterpillars of various types of moths and butterflies, as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, and flour mills and grain-storage facilities. It has also been observed to parasitize other moths such as ''Cadra calidella''—in laboratory experiments working with ''C. calidella'', many of the moths were diseased due to this parasite. During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called delta endotoxins, that have insecticidal action. This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes, such as Bt corn. Many crystal-producing Bt strains, though, do not have insecticidal properties. The subspecies ''israelensis'' is commonly used for control of mosq ...
