A survey was conducted in order to assess the losses of maize under farmers’ storage conditions in the Western hills of Nepal in 2014. The survey area included Thanapati Village Development Committee (VDC) of Gulmi, Aalamdebi VDC of Syangja, Khasauli VDC of Palpa and Baglung municipality-12, Baglung district. Primary information was collected through semi-structured questionnaires among the heterogenous groups of the farming communities. Survey revealed that about 61% respondents reported the storage pest as the major pests and about 12% respondents reported that field pests as the major pests in the western hills. Maize weevil (Sitophylus zeamais Mostsch.) and Angoumois grain moth (Sitotroga cerealella Oliv.) were found to be major storage insect pests in surveyed areas. Majority of respondents (39%) presumed on 10-20% losses during storage. Among the other biotic factors, farmers ranked insect (42%), weeds (32%) and diseases (17%) respectively. Maize storage methods had distinct among the surveyed areas compared with Baglung district to other surveyed areas. In Baglung, about (73%) farmers had stored maize in the form of grain whereas in Palpa, Gulmi and Syangja, about (77%) farmers had practice of storing maize with husk for 5-7 months. Approximately, 40% respondents were using open floor in upper stair “Aanti”as a major maize storage place in Palpa, Gulmi and Syangja whereas almost (79%) of respondents were using sacks to store shelled grains in Baglung. Hence, there is ample opportunity to reduce the storage losses of maize depending upon the existing situation.Journal of Maize Research and Development (2015) 1(1):98-105DOI: http://dx.doi.org/10.5281/zenodo.34288

Structured Questionnaire

Insect pests are the major constraints of crop production. Mustard aphid is the major problems of rapeseed contributing mustard decline in Chitwan, Nepal. Semi-structured questionnaire survey was conducted on randomly selected farmers of Chainpir Village Development Committee (VDC), Chitwan after a pre-testing in Mangalpur VDC to study the farmers’ knowledge and management practices adopted against mustard aphid in Chitwan. Study revealed majority (60%) of the respondent suggested aphid as the major insect of rapeseed and moreover, 86% of the respondent experienced it to cause 25% loss to the crop yield. Much proportion of respondents (58%) also realized low temperature with high humidity at the time of flowering as a cause in higher aphid infestation. Farmers use 2-3 sprays of chemical insecticide to control aphid but was found to destroy natural enemies and bee population besides damaging natural environment and human health. Int. J. Appl. Sci.

Increased Susceptibility

Shelled corn stored in metal bins was sampled for insects on farms in the three westernmost crop reporting districts of Kentucky during 1989 and 1990 to identify pest insects present, determine the relative abundance of insect pests, and determine their geographic distributions. Thirty-six species or species groups were found in this survey. The most abundant insects were maize weevil, Sitophilus zeamais Motschulsky; Angoumois grain moth, Sitotroga cerealella (Olivier); flat grain, rusty grain, and flour mill beetles, Cryptolestes spp.; sawtoothed grain beetle, Oryzaephilus surinamensis (L.); foreign grain beetle, Ahasverus advena (Waltl); red and confused flour beetles, Tribolium spp.; and hairy fungus beetle, Typhaea stercorea (L.). Greater densities and numbers of species were caught later during the storage season and greater numbers were captured from the center versus edges of bins. The unexpectedly high abundance and widespread distribution of maize weevil and Angoumois grain moth suggests that greater care needs to be taken to manage these pests because of direct feeding damage and the resulting increased susceptibility of grain to secondary insect pests (e.g., Cryptolestes spp., sawtoothed grain beetle, Tribolium spp., foreign grain beetle, and hairy fungus beetle, which were commonly found) and fungi.

The Right

The establishment of native wildflower plantings in Florida can benefit agricultural producers as well as native pollinators and other beneficial insects (predators and parasitoids). The plantings do this by:  providing forage and nesting sites for bees, butterflies, and other pollinators, increasing wild bee numbers possibly across the farm, and increasing natural enemies of insect pests (that also depend on forage and nesting sites). This document discusses choosing the right mix of native plant species to benefit many pollinator species, as well as proper site selection, planting practices, and weed control techniques. Wildflower plots should be practical to manage, maximize benefits to wildlife, and fit into the overall management practices of the property.

The present paper deals with the study conducted during 2006-2008 to assess trade pattern of important medicinal plants in Chilime Village Development Committee (VDC) of Rasuwa district, Nepal. Chilime VDC is one of the important trade centres of medicinal plants in the district. We documented 60 species of important medicinal plants, including 26 species involved in trade. Among them, 12 most potentially traded species, which have been given high priority by the collectors and traders, were selected for the study of their market potential and their contribution to the local livelihood. About 40% of the households of Chilime VDC were found to be involved in the collection and trade of medicinal plants. Most of the collection (90%) was for trade, which has supported up to 40% of family income contributing average household net profit of NRs 9,000 per year. The local traders were also making a good profit from medicinal plants with annual net contribution of about NRs 0.25 million per trader. But only 50% of actual traded quantity was registered at DFO resulting low revenue collection (only 43% of the expected). This shows that illegal trade is a common practice in the area by which the local traders increase their profit because they do not have to pay revenue. Thus strong mechanisms should be developed to stop illegal trade of medicinal plants and to promote revenue generation.

 On-farm experiment was conducted in eight farmers’ field, of Khasyoli village development committee (952 to 1415 masl), Nepal, from April to September, 2011 to address the major constraint (nutrient management) to maize production through site-specific nutrient management (SSNM) as this approach is popular among scientists. The experiment comprised three nutrient omission plots (0N, 0P, and 0K), an ample NPK plot, and a farmers’ fertilization practice (FFP) plot, arranged in randomized complete block design. Farmers planted open pollinated variety (Manakamana-3) and managed in their way. Field-specific NPK application rates were calculated by considering nutrient demand, indigenous NPK supply and recovery efficiency of fertilizers. Grain yield in FFP (2.32 Mg/ha) and 0N (1.79 Mg/ha) plots differed significantly from each other and rest of the treatments, but was statistically similar among 0P (3.18 Mg/ha), 0K (3.40 Mg/ha) and ample NPK (3.38 Mg/ha) plots. Post-harvest grain and stover analysis revealed that indigenous NPK supply (20-71 kg N, 19-68 kg P2O5 and 51-164 kg K2O/ha) of soil vary among the farmers’ field. Moreover, soil was poor in indigenous N supply (42 kg/ha), but rich in indigenous P2O5 (35 kg/ha) and K2O (90 kg/ha) supply, on an average. As per the principles of SSNM, the initial fertilizer recommendation made can vary from 40-222 kg N, 0- 93 kg P2O5, and 0-50 kg K2O/ha. On an average, farmers may apply no or lower dose of P2O5 (18 kg/ha) and K2O (3 kg/ha) but need to significantly increase dose of N (143 kg/ha) fertilizer for enhancing soil and maize productivity.Int J Appl Sci Biotechnol, Vol 3(2): 227-231 DOI: http://dx.doi.org/10.3126/ijasbt.v3i2.12538

Paddy Cultivation

Present paper has been focused on the changing aspects of paddy cultivation of Chakratir the VDC, Lamjung district after the implementation of Rain star Irrigation Project (RIP). The RIP is confined in 7 wards of the VDC, where only 3 and 4 wards are not covered. The study of changing scenario of paddy cultivation after the completion of RIP has been mainly based on the primary data. The study has found that various crops such as paddy, maize and millet were grown almost equally in the study area before the availability of irrigation facility. Due to the availability of irrigation facility, the crop production has been moved towards paddy cultivation. Paddy has become the most important crop for consumption and income. Before irrigation project only 204 ha lands was occupied for paddy production whereas after the construction of the Project it was extended to 340 ha land.DOI: http://dx.doi.org/10.3126/ttp.v13i0.11541The Third PoleVol. 13, 2013page : 12-16

Behavioral Resistance

AbstractInsects have evolved a variety of physiological and behavioral responses to various toxins in natural and managed ecosystems. However, insect behavior is seldom considered in insecticide studies although insects are capable of changing their behavior in response to their sensory perception of insecticides, which may compromise insecticide efficacy. This is particularly serious for insect pests that are physiologically resistant to insecticides since insecticide avoidance may further compromise their management. Locomotion plays a major role determining insecticide exposure and was, therefore, considered in investigating the behavioral responses of male and female adult insects from an insecticide-susceptible and two insecticide-resistant strains of the maize weevil Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), a major pest of stored cereals. Different dose-dependent behavioral responses were expected among strains with behavioral resistance less likely to occur in physiologically resistant insects since they are able to withstand higher doses of insecticide. The behavioral responses to deltamethrin-sprayed surfaces differed among the maize weevil strains. Such responses were concentration-independent for all of the strains. Stimulus-independent behavioral resistance was unrelated to physiological resistance with one resistant strain exhibiting higher rates of flight take-off and the other resistant strain exhibiting lower flight take-off. Female mobility was similar for all strains, unlike male mobility. Males of each strain exhibited a pattern of mobility following the same trend of flight take-off. Behavioral patterns of response to insecticide are, therefore, variable among strains, particularly among insecticide-resistant strains, and worth considering in resistance surveys and management programs.
