    Abstract Background: Various innovative teaching methods have been designed in an attempt to provide millennial students an interactive and stimulating learning environment. A jigsaw method is one such form of cooperative learning that enables students to develop critical-thinking and ability for effective communication and promotes positive student attitudes toward their own learning. The present study was thus undertaken to introduce a jigsaw-based cooperative learning method and to understand the perception of the students and faculty.
    Methodology: This was a cross-sectional study conducted among second year MBBS students. Students were randomly divided into 10 parent groups, with 10 students each. The topic was divided into 10 subtopics. Each student in the parent group was allotted a sub-topic. The students who were given the same sub-topic assembled to form an expert group. They interacted and discussed the subtopic. Students finally returned to their parent groups for peer teaching and presentation. A validated questionnaire was used to gather students and faculty feedback. Descriptive statistics were used to analyze responses to the Likert scale questions. Qualitative data was analyzed using thematic analysis.
    Results: The present study included 95 s year MBBS students. Majority (81%) students agreed that this teaching learning method enhanced their communication skills. Seventy-five percent of the students agreed that the activity helped in overcoming shyness and hesitation in the class. Overall the faculty also agreed that the jigsaw method was helpful for the students.
    Conclusions: Cooperative learning like jigsaw facilitates learning allowing student-student discussion, improving communication and teaching skills.

    Abstract The sugarcane borer, Diatraea saccharalis (F.), is a pest of a variety of graminaceous crops in the southern United States, including sugarcane, maize, and rice in Louisiana. This study examined several aspects of D. saccharalis oviposition behavior on rice (Oryza sativa). The vertical distribution of egg masses on four phenological stages of rice in the field showed that D. saccharalis prefers to oviposit on the uppermost portions of rice plants, regardless of plant stage. In greenhouse choice experiments, females strongly preferred plants at the boot and panicle differentiation stages over plants at the tillering stage for oviposition. Greenhouse studies were also conducted to quantify the oviposition preference of D. saccharalis for different cultivars of. When plants were at the tillering stage, cultivars Cocodrie, Priscilla, Bengal, Cheniere, and CL161 were more preferred than cultivars Jupiter, XL723, and XP744. When plants reached the panicle initiation stage, cultivars Cocodrie, CL161, and Priscilla were more preferred than Bengal, Cheniere, Jupiter, XL723, and XP744. Females also oviposited significantly more egg masses on the adaxial surfaces of rice leaves than on the abaxial surfaces. These results will facilitate scouting and management of sugarcane borer and can be used as a foundation for the development of sugarcane borer resistant cultivars.

    Abstract The sugarcane borer, Diatraea saccharalis (F.) (Lepidoptera: Crambidae), which attacks sugarcane, corn, sorghum, sudan grass and rice, is a major agronomic pest in the southeastern United States. This study was conducted to investigate the efficacy of different rates of Dermacor-X-100® (active ingredient, chlorantraniliprole) seed treatments on D. saccharalis in rice in the laboratory, greenhouse and field. In laboratory assays using cut stems, Dermacor-X-100® resulted in 40–50% more mortality than in the control, while in greenhouse intact plant assays Dermacor-X-100® resulted in approximately 70–80% higher mortality compared to controls. In the field study, Dermacor-X-100® seed treatment resulted in significantly lower numbers of borer entry and exit holes per plant. Results from this study suggest that Dermacor-X-100® seed treatment could be used as a valuable component of integrated pest management program for stem borers in Louisiana rice. As the boring behavior of larvae, life cycle and injury caused by most stem borers are generally similar, and because the active ingredient in Dermacor-X-100® is highly efficacious against lepidopteran pests, results for D. saccharalis may extend to management of other stem boring species as well.

    Abstract Phenacoccus solenopsis, the cotton mealy bug, has emerged as a serious pest of cotton in India, necessitating basic studies on its development and survival at different temperatures (20, 25, 30 and 35 °C) and relative humidities (RH) (65, 75 and 85 ± 1 %) levels to ascertain optimal population growth. A life table was constructed using temperature and humidity. The nymphal duration was 20.2 d at 35 ± 1 °C and 65 ± 1% RH, but lengthened to 26.6 days at 20 ± 1 °C and both RH combinations. Adult longevity was 16.4 days at 20 ± 1° C and 65% RH, but 10.8 days at 35 °C at the same RH; however it was 6.4 days at a temperature of 20 ± 1 °C and 75% RH. Fecundity was at its maximum (489 nymphs/female) at 35 ± 1 °C and 65% RH, with lower fecundity at 75% RH across all temperature levels. The net reproductive rate (Rₒ) and finite rate of increase (λ) were 141.3 females/female/generation and 1.24 fold per female per day, respectively at 35 ± 1 °C and 65% RH suggesting that the population would increase more than 140 times per generation and 1.24 times per female per day. The rates of increase at higher relative humidities were generally lower than at 65% RH. Nymphs failed to complete development at 85% RH at all temperature levels. The intrinsic rate of increase (rₘ) was the highest (0.215) at 35 °C in combination with 65% RH. Our results suggest that 35 ± 1°C and 65% RH is the most favorable temperature and RH combination for the optimal population growth of the Punjab strain of P. solenopsis. Our study also predicts the expansion of this pest to other parts of the world in which the average temperature equals to 35 °C with 65% RH.
