“…The damage to stored food products caused by insects accounts for about 5-10 % in the temperate regions of the world and 20-30 % in the tropical countries (Rajashekar et al 2010;Nakakita 1998). Management of these stored product insect pests mainly involves the use of synthetic pesticides in the form of fumigants and as residual contact insecticides (Devi and Devi 2013;Jaya et al 2012;Pandey et al 2012).…”

The susceptibility of the developmental stages of rust-red flour beetle, Tribolium castaneum to a range of concentrations of phosphine over varying durations from 24 to 168 h was reconnoitered in the laboratory at 25 ± 2°C. Responses of the life stages exposed to phosphine were compared with those of un-treated controls over 24, 48, 72, 96, 120, 144 and 168 h exposures and mortality was assessed after 14 days. Among the life stages tested, pupae were more tolerant to phosphine followed by the egg and the larval instars. At 24 h, the maximum LC 50 value was observed in case of egg; 1.571 mgL −1 ; followed by the pupae, 6 th instar, 4 th instar and 2 nd instar larvae with LC 50 values of 1.184, 0.336, 0.212 and 0.081 mgL −1 respectively. However, continued exposure of the developmental stages to phosphine, recorded maximum LC values in the pupae followed by egg and the larval instars. A linear increase in the mortality response was witnessed in all the insect stages when the exposure periods were extended from 24 to 168 h with increasing concentrations of phosphine, conversely significant increase in mortality was greatly apparent during the initial treatment periods.

“…However, the implications of these on the health and environment have revived interest in the development of 'safer compounds' as grain protectants using the knowledge base of plants. (George et al 1999;Rajendran andSriranjini 2008 andRajashekar et al 2010) The essential oils of some spices are reported to exhibit insecticidal activity, (Owolabi et al 2009). However, knowledge on their application as insecticidal, antifeedant or antiovipositional agent is limited.…”

Eighteen spices were screened for their insecticidal potential and antiovipositional properties against the rice weevil-Sitophilus oryzae-a serious insect pest of stored food grains. The bioefficacy of the powders and hexane extracts of selected spices were determined by assessing the toxicity, effect on F 1 progeny, contact toxicity, persistence and seed viability. Responses varied with the spices, dosage and exposure time. Powders of mace and pepper, at 1% level were highly effective resulting in total mortality of S. oryzae by one week followed by nutmeg and clove with 100% mortality and cinnamon and star anise with 90% mortality at 5% concentration. These spices also completely inhibited F 1 progeny. The hexane extracts of these spices at 1,000 ppm showed insecticidal activity, with pepper extract recording 100% mortality by 5 days. S. oryzae was susceptible to clove oil resulting in 92% mortality. Mortality was 51.63% in nutmeg, 66.6% in cinnamon, and 79.8% in case of mace and star anise. Hexane extracts of star anise, cinnamon and clove at 0.59 μl/cm 2 on filter paper discs induced 100% mortality by 72 h. These spices offered protection to wheat up to 9 months without affecting seed germination thereby showing promise as grain protectants.

“…4 tonnes/ha (Anonymous, 2015a); out of which loss due to insect pests is about 26% as shown in figure 1 (Anonymous, 2015b) and food grain accounts for 20-25% damage by storage insect pests (Rajashekar et al, 2010) which is really a brainstorming matter. Among various storage insect pests Angoumois grain moth (Sitotroga cerealella), maize/ rice weevil (Sitophilus oryzae), lesser grain borer (Rhyzopertha dominica), khapra beetle (Trogoderma granarium), rust-red flour beetle (Tribolium castaneum), legume weevil (Callosobruchus sp.)…”
