Ni ibihe bintu by'ingenzi ukwiye kumenya kuri Abamectin?

AbamectinIkoreshwa cyane cyane mu kurwanya Plutella xylostella, Pieris rapae, Spodoptera exigua, Spodoptera litura, leafminers, leaf rollers, Manduca sexta, root-knot nematodes, aphids n'ibindi bikoko bitandukanye. Uburyo ikora ni ugukangura irekurwa rya aside γ-aminobutyric (GABA), ibuza imitsi kuyobora udukoko, amaherezo bigatera ubumuga bw'udukoko, kureka kurya no gupfa.

Udukoko dufite uburyo bwiza bwo kurwanya udukokoAbamectin

1. Uburyo bwo kurwanya udukoko

Abamectin ishobora gukoreshwa mu kurwanya Plutella xylostella, Pieris rapae, leaf miners, Liriomyza spp., Spodoptera exigua, Spodoptera litura, Phyllonorycter ringoniella, leafminer moths, leaf roller moths, Heliothis virescens, Manduca sexta, root-knot nematodes, aphids n'ubwoko bwose bw'udukoko duto (harimo Hawthorn Spider Mite, European Red Mite, Two-spotted Spider Mite, Citrus Red Mite, Rust Mite, Pear Psylla, nibindi).

2. Uburyo bwo gukora

Abamectin yibasira receptor za GABAA kuri neuronapses cyangwa neuronemuscular synapses z'udukoko, ikabangamira uburyo bwo kohereza ibimenyetso ku miyoboro y'udukoko. Ikangura imiyoboro y'ubwonko kugira ngo irekure umusemburo wa neurotransmitter aside γ-aminobutyric (GABA), igakora imiyoboro ya ion ya chloride ivanzwe na GABA kandi ikongera igihe cyo kuyifungura. Ubwinshi bw'iyoni ya chloride butera hyperpolarization y'ubushobozi bw'imiyoboro y'ubwonko, bigatuma imiyoboro y'ubwonko ikomeza kubangamira. Ibi bibuza itumanaho ry'ibimenyetso hagati y'imiyoboro y'ubwonko n'imitsi, bigatera ubumuga, kureka kurya no gupfa kw'udukoko.
