Abstract

Background: Garcil (Allium sativum) is an important commodity and has high economic value in Indonesia.Studies have been using water extracts of garcil as larval mortality Crocidolomia binotalis in august –september 2014. This study aimed to determine the effect of water extract of Garlic (Allium sativum) on mortality of larvae on cabbage plants Crocidolomia binotalis. Methods: This study was an experimental study, using a rando mized block design (RBD), using the control group, and treatment concentraction of water extracts of garlic (Allium sativum). Concentration ranging from 2%, 4%, 6%, 8% with observation for 24 hours. Data effect of aqueous extract of garlic is effective against larval mortality Crocidolomia binotalis analyzed by real difference test (LSD) and the determination of the value of LC50, using SPSS. Result: The results showed the water extract of garlic is effective for larval mortality Crocidolomia binotalis is the concentration of 6% and of probit analysis LC50 values of 4,632%. Conclusion: Concentration of 4,632% aqueous extract of garlic (Allium sativum) can kill larvae Crocidolomia binotalis after administration of the extract and observation for 24 hours

Abstract

The use of pesticides botanists to be the solution due to the use of chemical pesticides in controlling pests unwise caused negative impact on the environment. This study aims to determine the effectiveness of the leaves of the Annona muricata on mortality of Sitophilus oryzae. Research conducted at the Laboratory of Taxonomy Department of Biology, Faculty of Mathematics and Natural Sciences Ambon. The treatments tested was the heavy leaves of the soursop, consists of five levels, namely 0 g, 20 g, 25 g, 30 g and 35 g, using a completely randomized design with four replications. The results showed that showed that the treatment leaves of the Annona muricata which is effective against Sitophilus oryzae mortality was 35 g with a mortality rate reached 78.31%.

Abstract

Red chili (Capsicum annuum L.) is an important commodity and has high economic value in Indonesia. Problems encountered in the cultivation of chili in Indonesia decreased productivity due to pests attack. Aphids (Aphis gossypii) is a major pest that attacks the chili leaves. This research was aimed to determine the effectiveness of ered pepper (Capsicum annuum L.) extract on mortality of aphids; especially  the effective concentration and LC50 of red chili extract on mortality of aphids (Aphis gossypii). This research tested five concentration of chili extract treatments with four replicates each. Third instar of nymphs were fasted for 30 minutes before, then nymphs attached to the chili leaves were trasferred into the petri dish. Each petri dish filled with 10 nymph of Aphis gossypii. Red chili extract of 3%, 5%, 7% and 9% sprayed 3 times on the nymph. Mortality rate was calculated 24 hours after application. The results showed that the extract of red pepper were effective to kill aphids nymphs, the lowest mortality was  35% at a concentration of 3% and the highest one was up to 92.5% at a concentration of 9%. Effective concentration (LC50) extract of red pepper that cause 50% of the mortality of the aphids for 24 hours of testing was  7.46%.
