The red palm weevil Rhynchophorus ferrugineus

Originally from tropical Asia, the red palm weevil Rhynchophorus ferrugineus has spread to Africa and Europe and is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm.

The adult female lays approximately two hundred eggs on new growth in the crown of the palm, at the base of young leaves, or in open lesions on the plant ;  the larvae,  tunneling through the internal tissue of the tree for about a month can occasionally grow to a length of six to seven centimeters; they will leave the tree and form a cocoon built of dry palm fibers in leaf litter at the base of the tree. The total life cycle takes about 7–10 weeks

Hoya imperialis white : limited success with planting cuts or not ?

Comment about Hoya imperialis white
" ... Thanks for good cooperation. Packet came safely, it was captured on the border, but everything is OK with plants. They are in good condition, the small rooted are in the best look, but I have problem with one plant... It is the second time, it comes to me in very bad condition - .. Hoya imperialis white. .. it had yellow leaves and .. completely dropped out. Only one leaf stayed with plant, but it soon got yellow and went away... "
Comment by aleyagarden
  In our humid environment Imperialis is much harder to grow, perhaps even harder than praetorii, we also lose a lot of imperialis. At the moment out of 50 cuts in our nursery we are expecting to get only 2. This is why it is so expensive. We have tried everything , shade, chemicals etc the rate of survival is very low.

However a Hoya collector in Europe posted this message, saying that even without leaves she successfully plant Hoya imperialis cuts.

Hoya mindorensis Red Star : high germination of the seeds

Hoya seed germination test : on the image each red spot is a germinating seed of Hoya mindorensis Red Star. These seeds were collected 4 days ago and packed in closed humid bags the following day ( 28 November ).

 To detect the green parts and apply the red spots the image is enlarged. After this it is compressed so the quality of this picture doesn't allow detection by naked eye.

Seeds of Hoya meredithii

Most Hoya varieties always produce seeds with high germination rates if planted soon after collect, ( we plant them in germinating bags ) others produce only non fertile seeds.

The test at this link shows how fertility is affected by the length of time between collect and planting :
http://aleyagarden-hoya.blogspot.com/2012/10/hoya-seeds-germination-test.html

Also some pods seem to give more viable seeds than other pods on the same plant.

But Hoya seeds can also be viable and dormant, their dormancy can last several months.  

The germination rate of Hoya meredithii seeds ( in picture below ) can be very low :  from a pod of selected meredithii seeds ( the flat seeds were discarded ) only one germinated in about 40



The followings Hoya seeds seem to have low or no germination :

carnosa red
pahang 
vitellina
plicata
sweet scent
longifolia long leaf
leucardenasiana
mindorensis pink
parasitica
parasitika x pachiclada
estrella waterfall

Seeds of Hoya kerrii and Hoya juannguoiana under glass

We have started the project of a mini gardening  today : we have taken seeds of Hoya kerrii and Hoya juannguoiana out from closed humid bags where they were germinating to transfer them onto soft paper at the bottom of glass bottles, then we closed the tops.

 

   

 

These seeds below are the Hoya kerrii

Mites species belonging to two common genera (Tenuipalpus and Brevipalpus) are known to attack economic plants and cause significant damages.

Tenuipalpidae, also called "flat mites" or "false spider mites", are closely related to the Tetranychidae. They are reddish, slow moving, and normally feed near the midrib or veins on the underside of leaves. Tenuipalpus pacificus attacks orchids.

Brevipalpus obovatus and Brevipalpus phoenicis attack over 50 genera of ornamental plants. 

In the two pictures below are mites of the Tenuipalpus genus

Brevipalpus phoenicis

 

The flat mite Brevipalpus phoenicis ( on the left ) has become established in numerous southern states of the USA, throughout the mainland from Florida to California, and also in Hawaii.
