Cypermethrin was applied either alone or in combination with leaf and seed extracts of neem (Azadirachta indica A. Juss) to four strains of the adult red flour beetle Tribolium castaneum (Herbst) and the mortality was assessed after 24 and 48 hrs of treatments. The LD50 values were calculated as 0.0072, 0.0105, 0.0056 and 0.0124 μgcm-2 after 24 hours and 0.0041, 0.0076, 0.0046 and 0.0097 μgcm-2 after 48 hours of treatment for the Local, CR-1, FSS-II and CTC-12 strains respectively. The results showed synergism when applied in combined doses of cypermethrin and leaf and seed extracts with petroleum spirit, ethyl acetate and methanol. Leaf extract in acetone had an insignificant effect showing its inertness with cypermethrin excepting 24 hrs after treatment of Local strain and 48 hrs after treatment of CTC-12 strain. Seed extract in methanol in Local strain showed insignificant effect after 24 hrs of treatment but a synergistic effect occurred after 48 hrs of treatment.

Experiments were carried out to evaluate the toxicity of six botanicals, Bazna (Zanthoxylum rhetsa), Ghora-neem (Melia sempervirens), Hijal (Barringtonia acutangula), Karanja (Pongamia pinnata), Mahogoni (Swietenia mahagoni) and Neem (Azadirachta indica) against red flour beetle, Tribolium castaneum Herbst. Leaf and seed extracts were prepared by using acetone, methanol and water as solvents. The results showed that extracts of all the six plants had direct toxic effect on red flour beetle. Among them, Neem seed extract showed the highest toxic effect (mortality, 52.50%), whereas Hijal leaf extract possessed the lowest toxic effect (mortality, 22.24%). Among the solvents, acetone extract showed more toxic effect than other extracts. Seed extracts of respective plants were slightly more toxic than leaf extract. The effectiveness of most of the plant extracts increased proportionally with the increase of doses and decreased with time.

Insecticidal activity of leaf and seed extracts of Tephrosia vogelii J. D. Hooker (Leguminosae) and fruit extract of Piper cubeba L. (Piperaceae) on the cabbage head caterpillar, Crocidolomia pavonana (L.) (Lepidoptera: Crambidae).  Ethyl acetate leaf and seed extracts of Tephrosia vogelii and a solid fraction of ethyl acetate fruit extract of Piper cubeba were evaluated for their insecticidal activity on second-instar larvae Crocidolomia pavonana by a leaf-residue feeding method in the laboratory.  Leaf extracts of purple and white-flowered T. vogelii showed the same pattern of component separation on silica gel TLC plate (Rf between 0.21 and 0.94), and likewise the separation of components of seed extracts of purple and white-flowered T. vogelii (Rf between 0.31 and 0.96).  All four kinds of T. vogelii extracts showed intense UV-absorbing nonpolar spots (Rf > 0.8).  Based on LC50 ratio at day 4, leaf extract of purple-flowered T. vogelii (LC50 0.075%) was 4.30, 2.70, 2.21, and 1.64 times more toxic than fruit extract of P. cubeba, seed extract of white-flowered T. vogelii, seed extract of purple-flowered T. vogelii, and leaf extract of white-flowered T. vogelii, respectively.  All T. vogelii extracts were more toxic to C. pavonana larvae than P. cubeba fruit extract.  At LC95 level, a mixture of leaf extract of purple-flowered T. vogelii and fruit extract of P. cubeba (5:9, w/w) was more toxic to C. pavonana larvae than each extract tested separately.  This extract mixture had synergistic joint action against C. pavonana larvae both at LC50 and LC95 level.  Thus, leaf extract of purple-flowered T. vogelii and its mixture with P. cubeba fruit extract are promising to be used for controlling C. pavonana.

An experiment has been conducted to find out the toxic effect of acetone extract of Sapium indicum seed, petroleum ether extract of Thevetia neriifolia seed kernel and Jatropha gossypifolia seed on the fecundity and fertility of Tribolium castaneum and Tribolium confusum. The results indicated that all the treatments significantly (P < 0.001) reduced the fecundity and fertility of both the insect species. However Jatropha gossypifolia seed extract did not reduce significantly the fertility of Tribolium castaneum in comparison with the control but a decline of fertility was observed with the increase of dose of treatment.

Insecticidal activity of the seed extracts of custard apple, Annona squamosa L. in petroleum spirit, ethyl acetate, acetone and methanol against Raj, CR 1, FSS II and CTC-12 strains of the red flour beetle, Tribolium castaneum (Herbst) was studied. The seeds were dried, powdered and extracted in Soxhlet`s apparatus in the solvents below 60°C. Extractions were applied on larvae and adult beetles in film residue methods and mortality was recorded after 24 h. For larval bioassay the highest toxicity was recorded for petroleum spirit extract (LD50= 0.03?g cm-2) in Raj strain and the lowest toxicity was for methanol extract (LD50=15.697?g cm-2) in FSS II strain. In adults petroleum spirit extract offered highest toxicity (LD50= 58.697?g cm-2) in CTC 12 strain and the lowest toxicity (LD50=22004.710?g cm-2) was for acetone extract in CR 1 strain. LD50, 95% confidence limits and regression equations are presented. Key words: Tribolium castaneum, Annona squamosa, custard apple, LD50 J. bio-sci. 14: 107-112, 2006

The insecticidal and repellent activity tests of the chloroform extracts of fruit, leaf, root and stem of Urena sinuata L. against the red flour beetle Tribolium castaneum L. adults have been conducted. The leaf, root and stem extracts showed high toxicity by giving mortality of the beetles within 30 min. of exposure. The LD50 values for the 12, 24, 36 and 48h of exposures were 0.354, 0.262, 0.209 and 0.196mg cm2 for the fruit extract; 0.587, 0.413, 0.355 and 0.299mg cm2 for the leaf extract; 0.440, 0.389, 0.340 and 0.268mg cm2 for the root extract and 0.968, 0.661, 0.491 and 0.362mg cm2 for the stem extract. The insecticidal activity can be arranged in the order of fruit> root> leaf> stem extracts. The root and stem showed repellent activity against T. castaneum adults at P<0.01 and P<0.05 levels of significance, while the fruit and the leaf extracts did not show repellency at all.

The aim of this research is to know the most effective concentration of liquid formulation of Kalanchoe pinnata leaf extract 50 EC and Azadirachta indica seed extract 50 EC against S. litura. The experiment was conducted at the Laboratory of Pesticides and Enviromental Toxicology, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran. The concentration were tested of each formulation were 1%, 2%, 3 %, 4%,and control.  The experiment arranged in completely randomized design (CRD) and replicated three times. The results showed that the formulation of A. indica seed extract 50 EC at concentration of 2%, 3%, and 4% effective against S. Litura larvae with mortality of 76.7%, 86.7, and 93.3%  This formulation also causing a decrease in feeding activity, weight, and lenghten the development time of S.litura larvae. Unlike the case with liquid formulations of K. pinnata 50 EC extract which was less toxic and did not show significant differences in feed intake, weight of larvae, and development time of larvae compared control treatment.                Keywords: Toxicity, mortality, growth dearragement, botanical insecticide.

Level Of Significance

Dose-mortality and repellent activity tests of the chloroform extracts of fruit, leaf, root and stem of Solanum ferox L. against the red flour beetle Tribolium castaneum (Herbst) adults have been done. The fruit, leaf and stem extracts offered promising toxicity to the beetles within 30 min. of exposure. The LD50 values for 30 min., 12, 24, 36 and 48h of exposures were 0.440, 0.247, 0.211, 0.207 and 0.164mg cm-2 respectively for the fruit extract; 2.394, 1.712, 1.540, 1.239 and 0.993mg cm-2 respectively for the leaf extract; and 4.918, 0.871, 0.546, 0.472 and 0.522mg cm-2 respectively for the stem extract. However, the root extract did not offer any mortality for 30 min. and 12h of exposure; and thus the LD50 values for 24, 36 and 48h of exposure were 6.667, 5.086 and 3.357mg cm-2 respectively. While the dose-mortality activity can be arranged in the order of fruit> leaf> stem> root extracts. The fruit and stem extracts showed repellent activity against T. castaneum adults at P<0.01 and the leaf extract at P<0.05 level of significance, while the root extract did not show any repellency.
