    Actually most of the fungicides I use are odourless. At the moment I'm using a copper fungicide, very effective. As for the bugs I use Malathion which is the smelliest but controls most insects except thrips. For the latter i use imidacloprid (Halloamey's recommendation), which is odourless and seems to control all other sucking insects as well. CTW it is a systemic insecticide. I try to use as little pesticide as possible but under our Malaysian conditions and growing outdoors 24/7, it is a necessary evil.

    From any agri shop under the trade name Confidor (Amey's recm) which is very expensive or the cheaper Palisade 18.2, which I use. You only need to use a very minute amount 2ml : 10 litres of water.

    Zain, Im having this problem as well. My Paphio niveum almost died bcoz of this bug. Luckily it still survive. As Yew's suggestion, malathion so far is doing its job. I dont like use pesticide esp malathion bcoz of its stinking smell but have no choice. Right now I spray on weekly basis (if I dont get lazy). Still frm time to time I can still see this bug appear somewhere and I just crush it.

    Almost 5 years of my local orchid collection hobby, this pest almost ruined every Philippine orchid.

    They lay eggs in young stems as their larvae consumes all what's soft and sweet inside the stem.
    They are responsible of killing the following plants I have since 3 years ago
    - Aerides (inflexa, odorata, quinquevulnera)
    - Dendrobium (bicaudatum, ceraula, cerinum, chameleon, conanthum, erosum, papilio, taurinum, victoriae-reginae, yeageri)
    - Paphiopedilum (argus, ciliolare, fowliei, hennisianum, philippinense, urbanianum)
    - Phalaenopsis (bastianii, equestris, pulchra, lueddemanniana)
    - Trichoglottis (amesiana, bataanensis, latisepala, philippinensis)
    - Tuberolabium (escritorii, quisumbingii, rhopalorachis, sarcochiliodes, woodii)


    and a lot of more...

    Every time I see them crawling any of my plants, I give them a merciless smash with my fingers.

    I hate them so much...

    I think that what Yew Sung said is right on the ball ; the damage looks like burn to me.
    I had a problem a year or so ago when I had my thermostat controlling the heating system fail, in the "heat on" position, at a time when the sun came out and I was away from home for a day or two ; when I got back the temperature was over 40 deg. C. It seems that growth is particularly susceptible at a particular stage - the newest cells in the leaf, close to the stem were the ones which burnt, not the older part of the leaf away from the stem.The black patches look just the same. In some of my plants, where buds were at a tender developing stage they burnt - for example with Paphs,I had a couple of cases where a new bud emerged on a good stem , but the bud was burnt and of course the flower never opened.
    As to beetles, of course there are so many - more beetles than all the other invertebrates put together I have read ! In my garden it tends to be their larvae ( grubs) which do the damage, eating their way through leaves or bulbs ( no greenhouse beetle pests I can think of, in UK ) and I have to spray my lilies with a systemic (Provado) to control lily beetle for example - otherwise they do so much damage that they don't make a bulb big enough to flower next year , and the year after they disappear for ever..
