Heliothis In Gram
About the Practice
2 to 3 fruits of yellow oleander (Thevetia nevifolia), 500 g fruits of neem (Azadirachta indica), 1 to 2 fruits of thorm apple (Datura metel) and 100 g leaves of custard apple (Annona squamosa) are crushed in 1 L of water and then kept for three months. As a remedy, 250 ml of mixture is filled in a pump and sprayed on the heliothis infested gram (Cicer arietinum) crop two times at the interval of 15 days. Thus, the crop is saved of the problem. This treatment provides 80-90% crop protection of the heliothis. It is a self-developed practice.

PAS 1:
"Put a thin layer, about 1 1/2 centimetres, of fresh neem leaves in the bottom of whatever container you use to store grain. On top of that put in a layer of sun dried grain about 30 centimetres thick. Then put in another thin layer of neem, and on top of that another 30 centimetres of grain. Keep on alternating a thin layer of neem leaves with a thicker layer of grain up to the top of the container. Then close it up. Your grain will be safe from insects." [Neem Protects Stored Grain, G. Venkataramani, Agricultural Correspondent, The Hindu, Kasturi Buildings, Anna Salai, Madras ‑ 600 002, INDIA.]

"Neem (Azadirachta indica A. Juss.) has been demonstrated to reduce insect populations in stored products through its toxic and growth-disrupting and other effects on the pests. Grain movement and percussion also help to kill pests in grain. The combination of neem and grain movement on population growth and development of four insect pests is reported in this study. Dried whole neem leaves, neem leaf powder and neem seed kernel oil were combined individually with dried beans and rice in separate experiments, and subjected to varying degrees of gentle grain tumbling. The results showed that the combined treatments were more effective in reducing populations and disturbing growth and development of Acanthoscelides obtectus (Say) (Bruchidae), Sitophilus oryzae (Linnaeus) (Curculionidae), Oryzaephilus surinamensis (Linnaeus) (Silvanidae) and Cryptolestes ferrugineus (Stephens) (Cucujidae) compared to the untreated control or the neem or tumbling treatments alone. This study demonstrates the potential of a simple, effective and cheap method of protecting stored seed or food grain in small-scale storage for resource-poor farmers who do not have access to sophisticated control methods, entoleters or other mechanical devices for grain protection.

"Toxicity of Thevetia peruviana (yellow oleander) against larvae of Anopheles stephensi and Aedes aegypti vectors of malaria and dengue. ABSTRACT The secondary metabolites (terpenes, acetogenins and alkaloids produced by the plants have been explored for their utility in mosquito control as it has been already proven that some of the plant compounds are toxic to the target organism but harmless to mankind. Basic research for the synthesis of new pesticides is need of the hour. This study was conducted using secondary metabolites of plant extract of Thevetia peruviana to study its larvicidal properties against the larvae of Malaria and Dengue vectors. The toxicity of the leaf extract of Thevetia peruviana was evaluated against the larvae of Anopheles stephensi, and Aedes aegypti mosquitoes. Mean LC50 values of the petroleum ether, chloroform, acetone and methanol extracts obtained from leaves of Thevetia peruviana against the larvae of An.stephensi and Aedes aegypti mosquitoes after 24 hours were determined as 0.045, >0.05, 0.026, 0041 and 0.038, >0.05, 0.021 and 0.036%, respectively. However delayed impact after 3 days with chloroform extract and indicated that the larvicidal action is probably due to the insect growth inhibition." [Yadav, Suresh & Singh, S & Mittal, Pradeep.

"The mosquito Culex quinquefasciatus Say, is the major vector of filariasis, Japanese encephalitis and other plagues throughout the world, especially in the tropical and subtropical countries. For many decades chemical insecticides are widely used to control mosquitoes. Mosquitoes have developed resistance against these chemical insecticides. Excessive use of such insecticides has also adversely affected the environment. There is an imperative demand to search novel eco-friendly substitutes which are more effective, safe and economical. Plant extracts with proven insecticidal properties are an alternate to these insecticides. The present study describes the larvicidal activity of Annona squamosa plant over the mosquito, C. quinquefasciatus. The average larval mortality percentage after 24 hours of exposure to the ethanolic leaf extract of A. squamosa was recorded as 20%, 30%, 50%, 68% and 100% in respective concentrations of 2 mg/ml, 4 mg/ml, 6 mg/ml, 8 mg/ml and 10 mg/ml. The results of the present study revealed that the ethanolic leaf extracts of A. squamosa plant can be used effectively as a potential, ecofriendly, biodegradable and economic larvicide in integrated mosquito control programme."
