Microplot experiments on flooded soil infested with Hirschmanniella oryzae were conducted to investigate the influence of the legum Sesbania rostrata as a rotat ion crop with rice, Oryza sativa L. cv. Moroberekan. To avoid a green manure effect f rom S. r'ostrata, all aerial parts were removed at harvest. The dry weight of paddy, culms and leaves, and n u m b e r of culms of rice following Sesb...

The invasive brown marmorated stink bug, Halyomorpha halys, poses significant risk to organic farming systems because they rely on biological control, nonsynthetic inputs, and cultural tactics for pest management. This study evaluated the potential of five crop plants (sorghum, admiral pea, millet, okra, and sunflower) to be used as trap crops under organic production in four mid-Atlantic state...

The western corn rootworm Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) and the northern corn rootworm Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae) are major pests of corn (Zea mays L.). Historically, crop rotation has been an effective management strategy, but both species have adapted to crop rotation in the Midwest. For both species in eastern Iowa, we...

Wildflower strip plantings in intensive agricultural systems have become a widespread tool for promoting pollination services and biological conservation because of their use by wasps and bees. Many of the trap-nesting wasps are important predators of common crop pests, and cavity-nesting bees that utilize trap-nests are important pollinators for native plants and many crops. The impact of wild...

the objective was to study the population development of tuta absoluta (meyrick, 1917) on tomato in greenhouse conditions at droh. the trial assessed the occurrence of t. absoluta adults from the month of october to may in traps; a low numbers is noted. the high numbers recorded (170 adults/greenhouse) are caught at the end of crop cycle. the mean number of capture is 22 adults/ week/ trap. reg...

Monitoring traps are important components of integrated pest management applied against important fruit fly pests, including Bactrocera oleae (Gmelin) and Ceratitis capitata (Widemann), Diptera of the Tephritidae family, which effect a crop-loss/per year calculated in billions of euros worldwide. Pests can be controlled with ground pesticide sprays, the efficiency of which depends on knowing th...

The whitefly Bemisia tabaci is an important pest of chilli peppers and a vector insect that causes yellow leaf disease. This study aimed to compare the population intensity its attacks on production in plots with or without trap crops. used eggplant, tomato mungbean as As main crop, Chilli pepper was planted measuring 7 m x 4 spacing 60 cm 70 cm. Trap crops were around plots, 16 plants each plo...

Crop losses to foraging elephants are one of the primary obstacles to the coexistence of elephants and people. Understanding whether some individuals in a population are more likely to forage on crops, and the temporal patterns of elephant visits to farms, is key to mitigating the negative impacts of elephants on farmers’ livelihoods. We used camera traps to study the crop foraging behaviour of...
