Critical Constraints

<p class="1Body">Post-harvest losses are recognized to be one of the critical constraints upon food security among farmers of poor resource in Africa.The use of botanical pesticides in pest management during storage against insects is often encouraged because synthetic insecticides produce multiple side-effects on human health and environment. Insecticidal activity of the hexane, dichloromethane, ethyl acetate and methanol extracts of bark of <em>Trichilia gilgiana</em> was tested on <em>Sitophilus zeamaïs</em>, <em>Tribolium castaneum </em>and <em>Rhyzopertha dominica</em>. The mortality rate was measured variable. The results of analysis showed that the mortality rate has a very highly significant variation following extracts, doses, insects and time considered (<em>P </em>&lt; 0.001). Extracts with ethyl acetate and hexane of <em>Trichilia gilgiana</em> are effective against <em>S. zeamais </em>at the highest doses (1 g/ 10 mL and 0.5 g/10 mL of solvent). These effective extracts were characterized by gas chromatography coupled with mass spectrometry. Molecules such as 2-Oxazalidone; thiocyanic acid; Methanethioamide, N,N-dimethyl; 2-Coumaranone and other were characterizated. These results may consolidate traditional use of <em>Trichilia gilgiana</em> in pest management<em>.</em></p>

Different Levels

Tetranychus urticae Koch is a phytophagous mite capable of altering the physiological processes of plants, causing damages estimated at USD$ 4500 per hectare, corresponding to approximately 30% of the total cost of pesticides used in some important crops. Several tools are used in the management of this pest, with chemical control being the most frequently exploited. Nevertheless, the use of chemically synthesized acaricides brings a number of disadvantages, such as the development of resistance by the pest, hormolygosis, incompatibility with natural predators, phytotoxicity, environmental pollution, and risks to human health. In that sense, the continuous search for botanical pesticides arises as a complementary alternative in the control of T. urticae Koch. Although a lot of information is unknown about its mechanisms of action and composition, there are multiple experiments in lab conditions that have been performed to determine the toxic effects of botanicals on this mite. Among the most studied botanical families for this purpose are plants from the Lamiaceae, the Asteraceae, the Myrtaceae, and the Apiaceae taxons. These are particularly abundant and exhibit several results at different levels; therefore, many of them can be considered as promising elements to be included into integrated pest management for controlling T. urticae.

Synthetic Pesticides

Pests are considered a major problem in agriculture as they cause a various degree of losses. The use of synthetic pesticides to control these pests has resulted in pest resurgences, pest resistance, environmental degradation and lethal effect to non-target organisms in the agro-ecosystems. To minimize or replace the use of synthetic pesticides, botanical pesticides are important alternatives. They possess a toxic effect against pest including repellent, antifeedant and antibiosis effect against insect growth. In Nepal, among 5,345 species of flowering plants, 324 species have pesticidal properties. Some of the botanicals like Neem, Tobacco, Sweet flag, Garlic, Mint, Ginger, Artemisia, Sichuan pepper, Adhatoda, Basil, Drum-stick, Jatropha, Polygonum, Lantana, Chinaberry etc are widely used in pest management and many types of research have been done to explore the potential of these botanicals. This study aims to review the insecticidal potential of these important ethnobotanical plants. The biopesticides made from these botanicals were found to be effective against various pests. However, efficacy was found to be variable and often lower than that of synthetic pesticides.

Plants play a vital role in human life since the beginning of life on earth. Plants are not only directly used as a feed and fodder for humans and animals but are also used as drugs, food additives, pesticides, in flavor and fragrances and dye and pigments. The plants produce compounds for their growth and development and also produce secondary metabolites which provide additional properties to plants. These secondary metabolites produced by plant are responsible for these activities. Plants as a whole or in extracts/fractions form have been used as pesticides for protection of plants since thousands of years. Pyrethrum, neem, rotenone are such plants which has been used in many cultures and traditions for crop protection since ages and hold relevance in today’s world as well. The plant extracts contain secondary metabolites which provide protection to plants against pests by either causing mortality of pests or act as repellent to them. They can also impact pests by causing anti-feedancy, toxicity, alters insects behavior during oviposition and mating and inhibition of progeny emergence in pests. Essential oils isolated from the plants have also pesticidal properties. Lemongrass essential oil, Citronella essential oils, Tea tree essential oils and Oregano essential oils are the commonly used essential oils against the pests. In this review, botanical pesticides are discussed and their role in pest management and their advantageous over synthetic pesticides in terms of biodegradability, posing no or low risk to humans, environment and non-target organisms. Also, the future of botanical pesticides is discussed where they can be an alternative to synthetic pesticides if more research is done on their stability, efficacy, safety, modes of action, cost reduction is done.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
