I-Raspberry flower beetle

I-Raspberry Flower Beetle (i-Anthonomus rubi) iyinkathazo enkulu yama-strawberries.

Lesi isilokazane esiyingozi kakhulu esitholakala lapho kukhula ama-strawberries nama-raspberries. Amabhungane amadala (angaba ngu-4 mm ngobukhulu, amnyama anezinwele ezimpunga) ebusika ezinsalela zezitshalo noma emhlabathini. Entwasahlobo (ngaphambi nasekuqaleni kokuqhakaza) ekushiseni kwe-12⁰C, ukuvundisa kuqala. Izimpawu zokuqala zokuncela izintwala ezincane yizimbobo ezincane ezisaqanda (1-2 mm ububanzi) emaqabunga. Ngaphambi kokuvuleka kwama-buds kuma-inflorescence (cishe amasonto ama-2 ngaphambi kokuqhakaza), abesifazane babekela amaqanda ngaphakathi kwama-buds angakathuthukisiwe bese beluma ku-peduncle yabo. Ihlumela elilodwa liqukethe iqanda elilodwa. Insikazi ngayinye izalela amaqanda angaba ngu-60 futhi ilimaza inani elifanayo lezimbali, eziqala ukubuna, zilenga esitshalweni, futhi ekugcineni zome futhi ziwele phansi. Konke ukukhula kwezibungu kwenzeka endaweni eyomile. Ukuthuthuka kuthatha amaviki ama-3. Ezimweni ezingavamile, i-raspberry weevil ingalimaza ama-buds afika ku-80% kuyo yonke ipulazi, ibangele ukulahlekelwa kwesivuno esikhulu kakhulu. Isizukulwane sesibili samabhungane sivela ekupheleni kukaJuni, sidla amaqabunga izinsuku ezimbalwa, bese siphuma ebusika. Umkhawulo wokulimaza (okungukuthi isidingo sokwelashwa okuvikela izitshalo) salesi zinambuzane ngaphambi kokuqhakaza izimbali ngumuntu omdala oyedwa kuma-inflorescence angama-1.

Ama-strawberries

- ngaphambi kokuqhakaza (ukuvulwa kwama-buds): ngemuva kokubona amaqabunga okuqala awonakele (izimbobo) noma amaqabunga alenga ku-peduncle elunywe, - ekuqaleni kokuqhakaza (ngemuva kokukhula kwezimbali zokuqala) ngemuva kokubona ukunyakaziswa kwama-inflorescence umuntu omdala. amabhungane.
