Kuye isigaba sesibungu, lapho besebancane badlula inqubo yokulala lapho basebenzisa khona vikela phakathi kwamashidi amabili nosilika. Njengabantu abadala zingakhula zifike kuma-5 cms., Ikhanda labo lehlukile ngoba limnyama bhuqe, umzimba ophuzi oluhlaza okotshani, imigqa emhlophe ezinhlangothini zomzimba okuhambisana namabala amnyama.

Izimpiko zazo zifinyelela ku-4 cm. futhi izala ngalinye liqukethe amaqanda aphakathi kuka-5 no-10 abekwa phezu kweqabunga futhi embozwe ngento ebonakalayo evikelayo. Ikhiqiza izizukulwane eziphakathi kwezine nezine ngonyaka, lokhu kanye nenkanuko yayo ebabayo kuchaza ikhono lazo icekela phansi izindawo ezinkulu zezitshalo.

I- i-bacillus turigiensisukuwusebenzisa ngokuwufafaza ku-boxwood futhi lolu ketshezi alunangozi ngokuphelele ezinyonini, ezincelisayo nasezinhlanzini, yize lubulala isibungu lapho sisebenzisa amaqabunga, ngoba ukwakheka kwayo kuthinta kuphela lesi silokazane. Ziyasetshenziswa futhi izingibe ze-pheromone, eklanyelwe ukuheha amabhu angamaduna futhi awashiye ebhajwe, ngaleyo ndlela evimbela ukuzala kwawo.

Lezi zinyathelo zihlose uku ukuqeda isifo futhi uyivimbele ekuqothuleni izindawo ezinkulu lapho kutshalwa khona i-boxwood futhi isetshenziswe ngokuhlobisa ngokusakazeka kwayo. Vele, ukukuqeda kunzima kakhulu ngoba kusho ukuthi, okokuqala, ukugwema ukuhweba kwezitshalo ezithile phakathi kwamazwe, into okunzima ukuyilawula.

Ukuqashelwa kwamasimu amakhulu kanye nokuqapha okufika ngesikhathi kanye ukubakhona kwezinambuzane zizokwenza umehluko ekusebenzeni ekwelapheni lesi silokazane ikakhulu uma sihlaselwa esigabeni saso sokuqala noma esizukulwaneni sokuqala samabhu.

Kulabo abayikhulisa ezindaweni ezincane nezilawulwa kakhulu, kunconywa kakhulu futhi kuyasebenza hlanza ibhokisi ngalinye kangcono noma ngabe lincane futhi lapho besesigabeni sabo sokulala ubusika, hlola kahle bese uthena zonke izindawo ezithintekile, ngaphambi kokuqala kwentwasahlobo faka umanyolo omuhle ogcwele izakhi zomzimba oqinisa isitshalo futhi usisize silwe namabhu futhi uma kudingeka sisebenzise umuthi othile ophephile wamakhemikhali.

Okubalulekile ukuhlasela isinambuzane zisuka nje.
