Mushonga wezvipembenene weQuality High Methoprene 95% TC nemutengo wakanakisisa

Tsananguro yeChigadzirwa

Ihomoni yezvipembenene inouraya utachiona yemhando yehomoni yezvipembenene. Homoni yezvipembenene inogona kudzora kukura kwayo, kukura kwayo, uye maitiro ayo ekuchinja. Basa guru rehomoni yezvipembenene nderekudzivirira kuchinja kwemakonye asati akura, kuchengetedza hunhu hwemakonye achiri mudiki, uye kuramba ari makonye mushure mekuoma.

Methoprene, sechinodzivirira mashizha efodya, chinokanganisa maitiro ekubvisa zvipembenene. Chinogona kukanganisa kukura nekukura kwezvipembenene zvefodya nefodya powder borers, zvichiita kuti zvipembenene zvikuru zvirasikirwe nekukwanisa kubereka, nokudaro zvichidzora kukura kwezvipembenene zvemashizha efodya akachengetwa.

Kushandiswa

Mahormone ezvipembenene haagone kuuraya zvipembenene zvakananga, anogona kungokonzera kuti zvife panguva yekuchinja kwechimiro, kana kuderedza huwandu hwevana kuburikidza nekusabereka kana kusachekwa kwemazai. Nokudaro, mhedzisiro yavo inononoka uye havakwanise kudzora nekukurumidza kukuvara kwezvipembenene zvinoputika, zvichideredza kushandiswa kwavo mukurima. Parizvino, inonyanya kushandiswa mune zvinotevera:

1. Kudzivirira nekudzivirira zvipembenene zvine hutano. Fenpropathrin inoshanda zvakanyanya kurwisa mapete ekuGerman uye inogona kukonzera kusabereka kuvakadzi nevarume vakuru. Kurapa mushonga uyu nguva dzose kunogona kuuparadza nekuda kwekusabereka mushure memwedzi mitanhatu kusvika pagore, uye inoshandawo kurwisa mapete makuru. Kugadzira methoprene inoburitsa mushonga kwenguva refu kunoshandawo mukudzivirira nekurapa nhata, umhutu, nenhunzi.

2. Kudzora zvipembenene zveHemiptera. Fenvalerate inoshanda mukudzivirira magreenhouse aphids ne whiteflies uye yakanyoreswa muUnited States. Asi kugadzikana kwayo hakuna kunaka kana ikashandiswa mumunda. Dioxycarb inoshanda mukudzivirira greenhouse whiteflies ne crustaceans.

3. Kudzivirira nekudzivirira zvipembenene zvinochengetwa mudura. Homoni iyi yevana inoshanda zvakanyanya kurwisa zvipembenene zveLepidoptera panguva yekuichengeta, zvakaita sezviyo, hupfu, nefodya. MuUnited States, yakaedzwa kuti inoshanda kurwisa zvipembenene zvakawanda zvinochengetwa mudura, zvakaita sefenpropathrin necarbendazim.

4. Kudzivirira uye kudzora masvosve. Fenpropathrin bait inogona kukanganisa kuchinja kwemakonye anokuvadza, kuita kuti masvosve asabereke, uye kudzora masvosve emukicheni zvinobudirira. Kunewo mishumo yekushandisa mahormone evana kurapa masvosve.

5. Wedzera kugadzirwa kwesiriki. Kupfapfaidza juvenile hormone kana pseudojuvenile hormone senge anti juvenile hormone pachigaro chesiriki (2-4 micrograms/musoro) kana pa 5th instar silkworm body (1-3 micrograms/musoro) kunogona kudzivirira kuchinja kwechimiro, kuwedzera nguva yechi5 instar larval nekupfuura zuva rimwe chete, kuwedzera kudya, kuwedzera saizi yemunhu mumwe nemumwe, uye kuwedzera kugadzirwa kwesiriki. Kazhinji, zvinogona kuwedzera huwandu hwe cocoons 10000 neinenge 15%.

Kushandisa Nzira

1. Chengeta mashizha efodya kudzivirira zvipembenene zvefodya. Pfapfaidza upfu hunonyungudika hwe41% ka40000 kupfuura mvura yacho zvakananga pamashizha efodya. Kuti uve nechokwadi chekuti pfapfaidzo yakafanana uye kuti mashizha efodya akafukidzwa zvakakwana, unogona kushandisa michina yekupfapfaidza yakawanda kana michina yekupfapfaidza yakaderera-yakananga inogona kushandiswa.

2. Kunzwa kwezvipembenene kumahormone evechidiki kunosiyana pamatanho akasiyana ekukura nekukura. Makonye kana kuti nymph anonyanya kunzwa padanho rekupedzisira, nepo mamwe matanho asinganyanyi kunzwa. Mukukura nekukura kwezvipembenene, nguva yakakodzera inosarudzwa uye mahormone evechidiki ekunze anoshandiswa kukanganisa kuenzana kwemahormone mumuviri wezvipembenene, zvichikonzera shanduko isina kujairika, kusabereka kwevakuru, kana kutadza kuchechenya mazai, nokudaro zvichizadzisa chinangwa chekudzora nekubvisa zvipembenene.

3. IC50 fenvalerate yeCulex pipiens larvae i0.48 micrograms pa litre, uye ID50 fenvalerate yewax moth pupae i2.2 micrograms pa pupa.
