ANNONACEAE
ANNONA CHERIMOLA Mill. Synonym: A.
tripetala. Cherimoya.
Petroleum ether and chloroform extracts
of the seeds were toxic to larvae of the
black carpet beetle and webbing clothes
moth, slightly toxic to Aedes mosquito
larvae, and nontoxic to German cockroaches,
milkweed bugs, and Anopheles
mosquito larvae. An alcohol extract was
toxic only to black carpet beetle larvae. -­
Heal and coworkers (93).
ANNONA DIVERSIFOLIA Safford.
An aqueous extract of the seeds was very
toxic to A'merican cockroaches when injected
into the blood stream, but German
cockroaches were unaffected after immersion
in the extract.--Heal and coworkers
(93 ).
ANNONA GLABRA L. Alligator apple.
An aqueous extract of the seeds was
toxic to American cockroaches when injected
into the blood stream; milkweed
bugs and German cockroaches were affected
slightly and not at all, respectively,
after immersion in the extract. A petroleum
ether e:lttract of the seeds was toxic to milkweed
bugs and larvae of the webbing clothes
moth, black carpet beetle, and Aedes mosquito;
it was nontoxic to German cockroaches
and Anopheles mosquito larvae.
Alcohol and chloroform extracts of the
seeds were toxic to larvae of the webbing
clothes moth and black carpet beetle, but
not to German cockroaches, milkweed bugs,
and Aedes and Anophele s mos quito larvae. - -
Heal and coworkers (93).
ANNONA MONTANA Macfad.
An aqueous extra ct of the branche sand
leaves was nontoxic to American cockroaches
when injected into the blood stream,
and German cockroaches and milkweed bugs
were unaffected after immersion in the
extract. An aqueous extract of the seeds
was toxic to American cockroaches and
milkweed bugs, but not to German cockroaches.--Heal
and coworkers (93).
l\NNONA MURICATA L. Sour sop.
The powdered seed was toxic to southern
armyworms and pea aphids, but not to celery
leaf tiers, large milkweed bugs, and two-
13
spotted spider mites.--Bottger and Jacob­
SOn (36).
The petroleum ether-soluble and -insoluble
fractions of an ethyl ether extractive
of the seeds were ineffective against auult
house flies.--Jacobson (108).
An aqueous ·extract of the seeds was toxic
to American cockroaches ,when injected into
the blood stream, but German cockroaches
and milkweed bugs were practically unaffected
after inunersion in the extract.
Petroleum ether and chloroform extracts
of the seeds were toxic to black carpet
beetle larvae, but nontoxic to German
cockroaches, milkweed bugs, and larva.e
of the we bbing clothe s moth and Aede s
and Anopheles mosquitoes.--Heal and coworkers
193).
ANNONA PALUSTRIS L.
An aqueous extract of the seeds was very
toxic to American cockroaches when injected
into the blood stream. Immersion
in the extract was toxic to milkweed bugs
but not to German cockroaches.--Heal and
coworkers (93).
ANNONA RETIGULATA L. Custard apple.
ANNONA SQUAMOSA L. Sugar apple.
The seeds and roots were extracted with
ethyl ether, and a resinous substance' was
obtained which is a contact poison of the
same order as rotenone against aphids. As
a stomach poison it is toxic and repellent
to diamondback moth larvae. Its toxicity
is less than that of rotenone to the sawtoothed
grain beetle. The toxicity is probably
due to a glyceride Or glycerides of a
hydroxylated unsaturated acid or acids of
high molecular weight.--Harper and coworkers
(87).
The powdered seeds are used in the
Philippine Islands as an insecticide and
against head lice.--auisumbing (179).
An aqueous extract of the seeds of A.
squamosa was toxic to American cockroache
s when injected into the blood stream;
immer s ion in the extract was toxic to rnilkweed
bugs but not to German cockroaches.
A petroleum ether extract of the seeds was
very toxic to larvae of the webbing clothes
moth, black carpet beetle, and Aedes mosquito,
slightly toxic to milkweed bugs, and
nontoxic to German cockroache sand
Anopheles mosquito larvae.--Heal and coworkers
(93).
Hot-pressed and heat-extracted oils of A.
squamosa seeds were highly' toxic contact
