Limes, Oranges, Bigarades and other citrus trees are attacked by a ho3t of scale insects. 
(1) Lecanium viride which is complitelv kept in check at high altitudes by Cephalosporinia 
lecanii and a little at low elevations. (2) Mvtilaspis oitricola which his fortunately beert 
found this year to be kept under control by the red fungus Sphoerostilbe cocophila. This" 
parasite lias been found on the hills and in the low country. (3) Aspidiofcus ficus which i3 
certainly parasitised as it disappears from plantations as suddenly as it makes its appearance. 
Sp raying with cheap fish oil soap made locally is necessary to combat 3cale insects. 
Roses bushes are attacked at night by Adoretus versutus and in the day time by Oxyco- 
tonia versicolor. Both these beetles are getting very common. They could be destroyed by 
Scoliid wasp parasites if it is decided to introduce the latter from Madagascar. 
Papaws (Papaya carica) are badly attacked by Diaspis pentagona, a very common scale 
insect in the Colony. White washing the stem of the trees every 3 mouths gave excellent 
results as a measure of combating this pest at the Botanic Station. 
Breadfruits (Astocarpus incisn), jack trees (Artoearpus integrifolia) are attacked by Aspi¬ 
diotus ficus and iccrja Seychellarum. 
Custard apples (Anona squamosa) Anona reticulata and soursop (Anona muricata) are at¬ 
tacked by Icarya Seychellarum, Asterolecanium pustulans var Seychellarum, and Saissetia 
hemisphevica. 
Coffee (Coffea liberica) is attacked by Lecanium viride, Saissetia hemispberica and Iscb- 
naspis fililormis scale insects. 
Palm oil (Eleis Guineensisb The leaves of this palm are badly infested with Ischnaspis 
filiformis. Scorching the palms with kerosene blast torches combined with judicious pruning 
is being tried. Tt has been found impossible to purchase blast torches but coconuts husks 
pipped in kerosene at the end nf long nole.a are used instead.

Mangoes (Mangifera, indica) are attacked by Yinsonia stellifera, Lecanium maugiferee 
and Iceiya Seychellarum. 
Sugar cane (Saccharum officinarum) is attacked by Trochorrohopalus strangulatus, a 
weevil which bores into the underground portion of the stem. The ravages of this insect are 
not considered as being important.
