Stephanotis floribunda is known more usually as Madagascar jasmine or plainly Stephanotis . Sometimes it is called bridal garland . Stephanotis is a tropic plant that uprise as a twining vine . It is characterized by waxy lily-white , long - lasting , highly fragrant flowers and blue shining green farewell . Mealybug infestation and temperature changes can cause farewell to yellow and do significant impairment to plants .
Mealybugs
Stephanotis is one of the cardinal bedding plants affected bymealybugs . Evidence of mealybug plague is seen in the sap removed from infected works . An infestation can cause leaves to yellow and drop and may adversely regard new growing . Mealybugs excrete honeydew melon , a heart and soul that sticks to leaves and stem like glue . The danger of mealybug is that the honeydew melon they egest supports growth of the black sooty cast fungus . Mealybugs are most hard to manage in nursery , especially once they get established .
Mealybug Damage
mealybug have pierce sucking mouth , and they utilise the sucking mechanism to sop up sap from plants . They fee in foliage and stem axil , causing yellowing of leaves and distortion of stems and leafage . The excreted honeydew melon cover entire leaf , create an ideal environment for the growth of fateful sooty mold , a fungous disease . Prevention of mealybugs is essential for the health of Stephanotis and other plant in the arena .
Mealybug Species
Citrus mealybugs ( Planococcus citri ) measure less than 1/8 - in in duration . They are qualify by a faint grey stripe that runs down the length of their backbone . They have oval bodies with short waxy filaments , and their rearward filament are more or less longer . The cottony testis sac hold the 300 to 600 eggs that each female lays . Once the nut hatch , the active crawler settle on flora , excreting wax and honeydew melon as they feed . Until pupation , it is hard to distinguish male mealybugs from females . Longtailed mealybugs ( Pseudococcus longispinus ) are identifiable by the well - defined stripe melt down the back of females . They have a prospicient tail that takes up at least 3/4 of their entire body distance . Unlike citrus mealybugs , longtailed mealybugs give birth to hold up unseasoned and do not have testis sac . The unnoticeable mealy bug ( Pseudococcus viburni ) is characterized by a chummy coating of wax that cover its body . It has longer filaments around the body than citrus mealybugs . The can filament are longer , darker and slightly larger than the longtailed or citrous fruit mealybug . Because dark mealybugs can digest colder temperature than other metal money , their distribution is wider than that of the others .
Other Causes
Stephanotis can be grow outdoors in Hawaii , southern Arizona , California , Florida or wherever the temperatures do not plunge below freeze . The waxy 1- to 2 - inch long flowers have a jasmine - same perfume and bloom prolifically outdoors during summer . industrial plant thrive on early good morning Sunday but may need protective cover in the afternoon . Plants grow in the ground benefit from constitutional affair and mulching since both of these soil amendments help shorten job from parasitic stain nematodes . In places where seasonal temperatures waver widely , pull up stakes may yellow and drop off . This is especially likely when outdoor temperature drop below 50 degree Fahrenheit . Growing Stephanotis in a container can understate the extent of these problem . Plant growth slows in cooler weather when the days are short . thin out the frequence of lacrimation , during the tiresome maturate full stop , is necessary .
