Abstrak. Peningkatan produktivitas kacang panjang dipengaruhi beberapa faktor, salah satunya yaitu pemupukan yang berimbang. Pupuk NPK berguna sebagai penyeimbang unsur hara makro dan mikro di dalam tanah karena mengandung nitrogen, posfor, kalium, kalsium, magnesium dibutuhkan tanaman. Salah satu hama penting budidaya adalah penggerek polong. Tujuan penelitian ini untuk mengetahui dosis pupuk ...

Studies on aggressiveness of parasitoids, as assessed by their parasitism against pests, used in biological-control programs are highly important to select the most suitable species and/or strain control insect pests. The present study investigated whether egg parasitoid Trichogramma galloi Zucchi, an efficient agent for sugarcane borer Diatraea saccharalis (Fabricius) Brazil, could be replaced...

An experiment was conducted during kharif season of 2022-2023 to evaluate the cost benefit ratio by using different insecticidal applications viz., Chlorantraniliprole 18.5 SC (0.5ml/l), Spinosad 45 (0.4ml/l), Nisco sixer plus (2ml/l), Bacillus thuringiensis 4% WSP (2gm/l), Beauveria bassiana 1.15% WP (5gm/l), Neem oil @2% (5ml/l), ½ dose + (2.25ml/l) and Control plot against gram pod borer, He...

Maize (Zea mays Linnaeus, 1753) is economically the most important crop in Serbia, while European corn borer Ostrinia nubilalis (Hübner, 1796) (Lepidoptera: Crambidae) its significant pest of this crop. One potentially successful and environmentally friendly method for biological control based on usage wasps from genus Trichogramma Westwood, 1833 (Hymenoptera: Trichogrammatidae), which parasiti...

the european corn borer, ostrinia nubilalis (hübner), is an important insect pest of corn, zea mays l., crop in moghan region. in field experiments, the density of eggs and larvae of o.nubilalis and percentage of eggs and larvae parasitisms were studied on four corn hybrids ns704 (commercial cultivar), ns770, ns640 and mv524 (cultivars with high yield). furthermore, in this study, the predators...

Abstract Kernels of sweet maize are directly consumed by humans. This high value crop is grown in arid and semi-arid regions western Jilin Province, China where trickle irrigation widely used larvae the corn borer, Ostrinia furnacalis Guenée (Lepidoptera: Crambidae), can cause significant kernel damage. Low humidity less conducive to efficacy biological control agent, Beauveria bassiana (Balsam...

This paper describes increment cores (a useful tool in forestry and wood technology) and their uses which include age determination, growth increment, specific gravity determination, fiber length measurements, fibril angle measurements, cell measurements, and pathological investigations. Also described is the use and care of the increment borer which is essential in obtaining good cores. A caut...
