INTRODUCTION:

Organic Farming is a type of sustainable land use that works entirely without synthetic fertilizer and chemical pesticides and systematically enhances the agro ecological system. Via standardization and quality seals, certified organic farming can be clearly distinguished from other sustainable types of farming.
Organic farming is related to the concepts of Sustainable Agriculture, especially with regard to the reduction of external inputs, as an attempt to achieve more environmental justice.
Historically, it did not originate from the universities but was developed by farmers and organizations supporting this type of agriculture in the industrialized countries as an explicit counter-movement to input-intensive, high-tech agriculture.
Organic farming relies on natural cycles. At the centre of this agricultural system is the maintenance and enhancement of soil fertility and the general rejection of synthetic fertilizer and pesticides.
The Codex Alimentarius of the FAO and the WHO describes organic farming on the basis of an environmental management system achieving sustainable productivity by promoting the ecosystem. Pest and weed control is maintained via various individual methods and through the mutual interdependence of the habitats of soil organisms and nutrients, plants, animals and human beings.
Whereas, FOAM defines the overarching goal of organic farming as: "Organic agriculture is a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects. Organic agriculture combines tradition, innovation and science to benefit the shared environment and promote fair relationship and a good quality of life for all involved."
Organic agriculture was first appeared as one of the priority sectors in Nepalese agriculture since the 10th Five Years Plan (2059/060-2063/064). But nowadays various institutions, individuals and farmers are emergently engaging in this field. There are various local organic practices; some practiced from the ages and some innovating new practices by farmers themselves. At present, some organic products such as coffee, tea, honey, large cardamom, ginger etc are exported to international market. Various institute and individuals think that organic movement in Nepal is quite slow in motion due to lack of clear vision of the government and distorted information flow from the different developmental projects

OBJECTIVES:
·         To know about the organic farming practices being used in the western mid hill areas of Nepal.
·         To know about the present farming situations of this area.
·         To know the condition of fertilizers and pesticides application in the farmers field.
·         To know whether they are using local resources available in their farm or not.
·         To aware the farmer about the harmful effects of excessive use of fertilizers as well as pesticides.

C)                Other information:
He knows about organic farming which is been practicing in his farm.

a)Rice cultivation practices:
i) Use of organic manures:
                FYM is used in rice field during transplanting time at the rate of 20-25 doko per ropani. There is no any use of green manures in his farm. He has used urine and dung in rice fields. He has used bio-pesticides as asuro, pati etc to control insects in his rice field.  He has some problems like unavailability of organic manure and lack of manpower.
ii) Use of organic pesticides:
               He uses urine of cow and buffalo to control the insects in his rice farm. He has no idea about the use of neem in rice field to control the insects.
iii) Use of bio-fertilizers:
             He knows about bio-fertilizer, but there is no any use of bio-fertilizers in his rice field.
iv) Use of agrochemicals:
              He uses DAP 5-6 kg per ropani before transplanting and uses urea at the time of weeding. He has not used pesticides in his farm.
v) Use of traditional varieties:
            He do not have indigenous varieties of rice in his farm. But he had cultivated madhese, dalle, jhinuwa,marsi,anadhi etc. But the yield of traditional varieties is low as compare to the traditional varieties so he uses commercial varieties rather than the traditional varieties.

b) Maize cultivation practices:
i) Use of organic manures:
            Similarly, there is use of FYM in his maize field at the rate of doko 5-10 per  ropani. There is no any use of green manure.


ii) Use of bio-fertilizer:
           There is no any uses of bio-fertilizers.
iii) Use of organic pesticides:
          He uses urine of cow and buffalo to control the insects but no idea about the use of Neem to control the insects in maize field.
iv)Use of agrochemicals:
         DAP and urea is used 50 kg in 7 ropani before planting. He has not use pesticides in his farm.
v) Use of traditional varieties:
        Purano makia is being used as indigenous varieties in his farm having high plant height.

d) Vegetables cultivation practices:
Vegetables are cultivated only in subsistence level in the kitchen garden. Well-decomposed FYM is used for the vegetable crops production. The chemical fertilizer as urea is used in very little quantity. Only the seasonal vegetables cultivated by the responded farmer, in which winter vegetables include cauliflower, cabbage, leafy vegetables and the summer vegetables include cucurbits, beans etc. The pheromone traps and cue-lure are not used during the vegetable crop production. Oil cakes produced from the farmer's own field are used in vegetables field.

Importance of insect

INTRODUCTION:
The word Insect is derived from the Latin word ‘Insectum’ which  means ‘to cut into’. The body of insects are segmented which seems like the body cut into different parts. Generally the body of insect is divided into 3 parts: head, thorax and abdomen; having 3 pairs of legs and usually 2 pairs of wings. And the study of insects is called entomology. Insects can be found in every environment on our planet. But  the majority of insects are found in the warm and moist tropics. Insects have adapted to a broad range of habitats, successfully finding their own niche, because they will consume almost any substance that h as nutritional value.
OBJECTIVES:

  1.  To be able to know the insects, entomology, characteristics of insects;
  2.  To know the importance of insects in human welfare;
  3.  To be able to differentiate the insects i.e. Beneficial and Harmful insects.
IMPORTANCE OF INSECTS:
When many people think of insects, they think of things that bite, sting, eat their flowers, or get in their food and they would just as soon kill everyone that they see. Many insects though, do a lot of good for people and this includes some insects that you may not expect to be good for anything.
Insects perform a vast number of important functions in our ecosystem. They aerate the soil, pollinate blossoms, and control insect and plant pests; they also decompose dead materials, thereby reintroducing nutrients into the soil. Burrowing bugs such as ants and beetles dig tunnels that provide channels for water, benefiting plants. Bees play a major role in pollinating fruit trees and flower blossoms. Gardeners love the big-eyed bug and praying mantis because they control the size of certain insect populations, such as aphids and caterpillars, which feed on new plant growth. Finally, all insects fertilize the soil with the nutrients from their droppings.

INSECTS AS POLLINATORS:
A number of insects, including different types of bees, butterflies, wasps, and some ants, are responsible for pollinating plants around the world. They transport pollen from the male stamen of a flower to the female pistil of another flower on the same plant or another within the same species, allowing for the combination of genes, fertilization, and sexual reproduction. some plants, including at least one- third  of the world’s agricultural crops, and an estimated 90% of all flowering species, are reliant on pollinators. It is a mutually beneficial relationship that ensures the survival of both plants and insects. Plants rely on pollinators to ensure reproduction, fruit set, and seed dispersal. Pollinator insects rely on plants for food and habitat. Without insects people who grow and sell fruit (everything from apples, to tomatoes) would have to find some way to spread the pollen themselves. Obviously, this would be very difficult and time consuming if they have thousands of plants. It is hard to estimate, but the economic value of this role alone is probably in the billions of dollars.

INSECTS AS PREDATORS:
Predatory, or insectivorous insects, eat other insects: pests that would otherwise feed on important crops and plants. Lacewings feed on the eggs and juvenile stages of a number of agricultural pests, such as some types of thrips, mites, whiteflies, melaybugs and the caterpillars and eggs of numerous pest moths. Ladybirds feed on aphids, melaybugs, spider mites and the eggs of some beetle and borer agricultural pests.

INSECTS AS PARASITOIDS:
Parasitoids live out most of their lifespan “attached” in some ways to another insect or being, and ultimately kill their host. The Braconidae family, made up of over 1000 species of tiny wasps, represents only one of the many examples: these wasps feed on, reproduce in, and eventually kill some very harmful caterpillar pests that damage agricultural crops, such as hornworms. The female braconid wasp lays her egg just under a hornworm’s skin, rendering it unable to continue feeding and damaging crops. After the wasp lays eggs hatch, the juveniles are ready to become adults, they will chew their way out of the hornworm and spin cocoons that protrude from its body. Once the adult wasps emerge from their cocoons, the hornworm perishes.

INSECTS AS INDUSTRIAL IMPORTANCE:
1.    HONEY BEE:
Honey bees are very much beneficial for mankind due to its production of nutritious honey and bee wax. Honey is very protenacious and also medicinally important and bee wax is also industrially important such as making candles etc. Bees are very important pollinators. Bees also teach us the lesson of laborious, co-operation and friendship.
2.    SILK WORMS:
Silk worm are highly important insects for human being as it produces silk which is used for making highly valuable silken cloths. The pupa of silk worm contains fat which is used in soap industries.
3.    LAC INSECTS:
Lac insects produce lac from their bodies which is beneficial for mankind. At the previous time, lac was used to make bangles. Now-a-days, lac is used to close the important official documents inside and dropping lac flame at the opening mouth of envelop and cloth bags.

INSECTS AS SCAVENGER:
Some insect’s acts as scavenger and feed upon decaying flesh and discarded materials. In this way, insects help us to clean our environment. Examples- Beetles flies.

INSECTS FEEDING ON WEEDS:
Harmful weeds like “kala jwar” which is found in east Nepal is controlled by a kind of fly cecidochares utilis. It lays eggs on the tender leaves and stem, produce larva on hatching. When larva produced, they destroy all weeds by consuming them.

INSECT AS ANIMAL FEED:
The insects and their larvae are used as food by man in different parts of the world. The larvae of bees, locusts etc. are used by man for eating. Insects are mostly used in animal feed like in fish meal, poultry meal. Insects are good source of animal protein and fat.

GALL MAKER INSECTS:
Some insects form gall in plants from which tonic acid is produced and used intensively in tanning. From galls, different types of dyes are also made.

USED IN SCIENTIFIC STUDY:
Many insects are used in scientific study in laboratory. Drosophila melanogaster is used in studying hereditary characters because of its short life span and easy to handle.  

INSECTS FOR BEAUTIFICATION AND ENTERTAINMENT:
Some insects produce sweet sound by which man can get entertainment. Butterflies, Beetles are used for decorating rooms. Artists take advantage of the insects by copying their structure and beautiful colors.

CONCLUSION:
We tend to think of “insects” and “bugs” synonymously with words like “harmful” and “pests”. However, only a very small fraction of the world’s insect population cause damage to the crops or harm humans. There are far more insects that can help in some way. Farmers can use techniques to attract beneficial insects to assists with pest management and pollination-and benefit enormously.
