Extracts of plant materials were prepared by employing three procedures, namely the cold-rolling, the soxhlet extraction and the water distillation methods. Three hundred and three extracts from 165 species of plants were tested against two-day-old adult oriental fruit flies using the mist spray at the rate of 1 g equivalent each. Extracts from plant parts which demonstrated moderately high to high toxicities were rhizomes of Alpinia officinarum, fruit skin of Annona squamosa, whole plant of Artemisia pallens, fruit of Croton tiglium, branches of Diospyros philippensis, whole plants of Euphorbia tirucalli, leaves of Nicotiana tabacum, leaves and branches of Pedilanthus tithymaloides, black seed of Piper nigrum, flowers of Tithonia diversifolia, grey rhizome of Zingiber officinale, and rhizome of 'changkhan' and 'phrataba'. Moderate toxicity effect was observed from extracts of Areca catechu nuts, leaves and branches of Azadirachta indica var. siamensis, fruit skin of Citrus sinensis, and roots of Stemona tuberosa. Mild toxicity was detected from extracts of Acorus calamus rhizomes, bulbs of Allium sativum, leaves of Alstonia macrophylla, seeds of Amomum cardamomum, whole plant of Anethum graveolens, roots of Artemisia vulgaris, roots of Chrysanthemum coronarium, rhizomes of Curcuma comosa, leaves and flowers of Euphorbia pulcherrima, fruit skin of Garcinia mangostana, rhizomes of Gastrochilus panduratus, flowers of Gomphrena globosa, leaves and flowers of Jussiaea linifolia, leaves of Lactuca sativa, leaves of Piper betle, leaves of Paederia foetida, leaves and flowers of Sphaeranthus africanus, leaves of Stephania hernandifolia, and rhizomes of Thunbergia laurifolia. Among unidentified plant species, rhizomes of 'khothongkae', 'khropchakkawan', 'phetma', 'plalai-yai', and 'sabu-thong' were under this catagory.

Survey on Philippine plants for insecticidal activity II. Biological activity of flower and leaf extracts from six species of plants on insects

Morallo-Rejesus, B; Tantengco, GB
NRCP Research Bulletin 41 (1-2): 41-70 (1989)

The volatile oils from the flowers and leaves of Lantana camara and Caesalpinia pulcherrima and leaves of Tithonia diversifolia and Tagetes erecta were topically evaluated on eight insect pests. Based on the LD50 values, the order of decreasing toxicity on the insects is: Musca domestica, Spodoptera exempta, Dysdercus cingulatus, Plutella xylostella, Sitophilus zeamais, Spodoptera litura,Rhizopherta dominica, Tribolium castaneum. The oils were not toxic to Ostrinia furnacalis. The oils from the flowers were more toxic than the leaf oils except on Spodoptera exempta and Rhizopherta dominica. The water extracts, likewise, exhibited anti-feedant effect on Plutella xylostella but not repellancy. The volatile oil from Lantana camara had eight components while Caesalpinia pulcherrima and Tagetes erecta had seven each. The oil from Azadirachta indica was non-toxic to all the aforementioned insects. The flavonoid from Caesalpinia pulcherrima flower was non-toxic against the insects used while the alkaloid from Lantana camara seeds was non-toxic against Dysdercus cingulatus.

Effectiveness of different width of fireline as affected by some topographic features in controlling of forest fires

Tubal, RS; Noble, BF
Ecosystems Research Digest-CAR 5 (2): 1-10 (1995)

A research was conducted to determine effectiveness of the different widths of fireline as affected by slope/terrain and the cost of fireline establishment. Study was conducted in 2 different sites in Benguet. The study was laid-out following the split-plot design with four replications. The different exposures served as replication. Since fireline construction aims to suppress and prevent the transfer of wildfire to adjacent areas being protected, the fireline to be established should be wide in width especially in areas with steep and very steep slopes.

Several kinds of plant substances having insecticidal effect were evaluated for their efficacy to control Palpita unionalis, an important pest of jasmine. The experiment was conducted in laboratory and in the field conditions. Materials used in the laboratory experiment were crude water extract of neem (Azadirachta indica) seed, ki pait (Tithonia diversifolia) leaves, kecubung (Datura speciosa) leaves, suren (Toona sureni) leaves and bark, sugar apple (Annona squamosa) leaves and seeds, soursop (Annona muricata) leaves, garlic (Allium sativum), toxic cassava leaves (Manihot sp.) and Bacillus thuringiensis. Seed extract and crude water extract of Annona muricata leaves, neem seeds and Bacillus thuringiensis at the recommended level were used in the field experiment. The results showed that in laboratory condition, crude water extracts of sugar apple seed was the most effective. This is then followed by neem seeds and Bacillus thuringiensis. Meanwhile Annona muricata leaves showed the next rank. In the field condition seed extract and crude water extract of Annona muricata and sugar apple seeds were the most effective in controlling Palpita unionalis compared to other substances. The results provide additional support in developing integrated pest management in jasmine.

Comparative study on the inhibitory effect of wild sunflower (Tithonia diversifolia (Herm SL) Gray) and common sunflower (Helianthus annuus L.) on rice and E. colona (L.) Link

Abeysekera, MMSAK; Robles, RP

Abstracts of papers presented at the 24th Annual Scientific Meeting of the Pest Management Council of the Philippines Inc., Cebu City, May 4-7, 1993; p

Inhibiting effects of wild sunflower (Tithonia diversifolia) and common sunflower (Helianthus annuus) are well documented. The comparative effect on rice and Echinochloa colona, however, have not been reported. This study was conducted to compare such inhibition. Fresh plant parts of wild sunflower and common sunflower were incorporated in soils into which rice and E. colona seeds were sown. Residues of both wild and common sunflower significantly inhibited the emergence and further growth of E. colona but not that of rice. No significant differences, however, were observed on the inhibitory effect of wild sunflower and common sunflower on E. colona. Rice grown in such residues increased in tiller number, leaf area and biomass production.

Wild sunflower: A cheap source of fertilizer

Pandosen, MD
Highland Agriculture and Resources Research and Development Consortium;La Trinidad;Benguet;Philippines

Techno Tips 1(1): ?

The rising cost of fertilizers require the need to continuously explore cheap alternatives to rehabilitate depleted soils and improve production. Studies have proven that the native sunflower plants (Tithonia diversifolia) is a good fertilizer substitute. Sunflower improves soil texture, increase soil ph and provides lasting effect on the soil to benefit subsequent crops. Being both a tropical and sub-tropical plant, the extensive use of native sunflower is practical. For sweet potato production, various fertilizers (fresh wild sunflower, garbage ash and commercial fertilizers) were evaluated. Among these, the highest yield was obtained from the plants fertilized with fresh sunflower (finely chopped leaves and stems about 1 foot from the tip and decomposed for 2 weeks) ant 1 and 2 tons per hectare. Application of fresh sunflower as fertilizer to sweet potato is therefore economically feasible specially in areas where wild sunflower is abound.

Not only for its beauty

Sarian, ZB (ed)
Manila Bulletin; March 15, 1997; p.C-6

The wild sunflower which abounds in Baguio and in some lowland areas is useful. Its showy flowers are a good source of pollen and nectar for honeybee culture. The leaves when decomposed also makes a potent fertilizer for vegetables, fruit trees and other crops.
