Abstract

Papaya mealybug, Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae), is an invasive pest that was detected for the first time in Indonesia in 2008. One of the common natural enemies is the predatory beetle Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae). The research was conducted with the objectives to determine the biology, life table parameters, and predation of C. montrouzieri on P. marginatus. Observation of biological and life table parameters and predation was conducted by introducing the predators into Petri dishes containing mealybugs. Eggs of C. montrouzieri hatched in 4.35 days. Mean developmental periods for 1st, 2nd, 3rd, and 4th instar larvae were 4.23; 4.21; 5.84; 5.93 days, respectively. The mean pre-pupal and pupal periods were 1.95 and 7.55 days, respectively. The longevity of male adults was 51.34 days, while that of females was 83.39 days. The number of eggs laid by a single female averaged 198.49. The net reproductive rate (Ro) was 117.11 individu/female/generation, intrinsic rate of increase (rm) was 0.073 individu/female/day, mean generation time (T) was 64.776 days, doubling time (Dt) was 9.426 days, and finite rate of increase (λ) was 1.076 per day.  The 4th instar larvae of C. montrouzieri was the most voracious with numbers of P. marginatus eggs, 1st, 2nd, 3rd instar nymphs or adults consumed were 188.0; 53.4; 44.0; 26.8; or 15.6; respectively. Manly's preference index suggested that larvae, as well as adults of C. montrouzieri, preferred eggs and 1st instar nymphs of P. marginatus over other mealybug stages. Our study indicates the high potential of C. montrouzieri in the biological control of P. marginatus.

Abstract

The issue underlying this study is the low learning outcomes of students in the topic of rights and obligations, which is caused by the limited variation in teaching models, leading to students being less engaged and easily bored during learning activities. The purpose of this study is to evaluate the impact of the Picture and Picture model on the learning outcomes of third-grade students at UPTD SDN 29 Mendo Barat. This study adopts a quantitative approach using the Pre-Experimental Design method with a One Group Pretest-Posttest Design. The sample in this study consists of all third-grade students at UPTD SDN 29 Mendo Barat. The data collection process used essay questions, and the data evaluation method employed the Shapiro-Wilk Normality Test for normality testing and the Wilcoxon Signed-Rank Test for hypothesis testing. The results of the study show a significant effect on the Pretest and Posttest outcomes. The normality test calculation for the Pretest was 0.053 > 0.05, and for the Posttest, it was 0.004 < 0.05, indicating that the data was not normally distributed. Therefore, hypothesis testing was conducted using the Wilcoxon Signed-Rank Test. The result of the hypothesis test was 0.000 < 0.05, meaning H_a was accepted and H_o was rejected. Thus, it can be concluded that the Picture and Picture model has an impact on the learning outcomes of third-grade students on the topic of rights and obligations at UPTD SDN 29 Mendo Barat.
