VBiology of Nephus regularis (Sicard) on The Invasive Mealybug, Phenacoccus madeirensis (Green) (Hemiptera: Pseudococcidae) | Chapter 8 | Research Perspective on Biological Science Vol. 2

The mealybug Phenacoccus madeirensis (Green) (Hemiptera: Pseudococcidae) is an invasive exotic pest with an extensive host of more than 130 genera of host plants from 51 families. P. madeirensis is considered one of the most economically significant pests of many fruits, fibre plants, food crops vegetable crops etc. The nymphal and the adult stages cause damage resulting in the withering and yellowing of the leaves. The plant protection products are not very efficient against mealybugs because they have a waxy coating on their bodies and a tendency to hide in cracks. The present study was carried out during the summer season (March-May 2019) in the laboratory of the AGPM Department, Shivaji University, Kolhapur to investigate the biology of N. regularis  on P. madeirensis under the controlled laboratory conditions (27±2ºC Temperature and 65± 5% RH). The observed mean pre-oviposition period of N. regularis  was 3.4 ± 1.07 days, whereas the recorded oviposition period was 32.6 ± 2.59 days. The post oviposition period of 20.4 ± 1.07 days was observed. The average egg-laying of 92.7 ± 8.41 eggs/ female was also noticed. The recorded mean incubation period was 5.2 ± 0.5 and the larval period lasted for about 10-13 days. The mean duration of pre-pupae and pupae was 1.5 ± 0.7 and 6.5 ± 0.8 days, respectively. The average longevity of male and female beetles noticed was 47.1 ± 1.7 and 58.4 ± 2.16 days, respectively.

Determining the Effects of Participatory Teaching Methods on Students’ Learning of Mathematics and Biology in Tanzania | Chapter 3 | Progress in Language, Literature and Education Research Vol. 8

This paper originates from a study on the effects of interactive teaching methods on students' learning of mathematics and biology at Tanzania's ordinary level secondary schools in Mwanza region. The qualitative technique was used in conjunction with the quantitative data. The 111 participants were chosen using simple random selection and selective sampling methods. Purposeful sampling was used to identify participants who could provide in-depth insights related to the participatory methods versus learning outcomes. Characteristics such as expertise, experiences and specific attributes were employed. To enhance generalizability of quantitative findings, random sampling technique was used to ensure that each member of the population has an equal chance of being selected. In addition, the study collected data via surveys, interviews, focus groups, observations, and documentary reviews. In contrast to the content analysis that was performed on the qualitative data, the quantitative data were analysed through processes like data cleaning, coding variables, dispersion and frequency distribution henceforth, bar charts, histogram, tables, figures and percentages were developed to facilitate interpretation. The research revealed that students had a positive attitude toward participative teaching methods and a desire to learn. According to studies, students' comprehension of math and biology at a basic level can be improved by adopting participatory teaching methods supported by suitable T/L materials and qualified teachers.

Study on DNA Binary Programming is Key to Understanding Evolutionary Biology | Chapter 9 | New Visions in Biological Science Vol. 1

 Each DNA molecule is made up of a base pair of nucleotides: guanine (G) and cytosine (C) or adenine (A) and thymine (T) (T). Long chains of GC and AT base molecules are akin to binary computer coding, in which each molecule is either a "GC" or a "AT" (rather than a "1" or a "0"). In comparison to primitive animals, advanced species have much less DNA encoding. The frog that developed from a fish no longer need the fish-specific components of its DNA and hence loses them. Similarly, the lizard loses the bits of its DNA that amphibians require, and so on up the evolutionary ladder. Every species possesses a disproportionately large amount of dormant DNA that it cannot potentially use. This is solely for the purpose of storing biological codes as a backup plan in the event of global extinctions. Every organism is thus preprogrammed with a binary encoded genetic template for what it could evolve into as a species, as well as limitless possibilities for new species evolution. Natural selection according to Darwin is only a minor part of this evolutionary process.

Hosts of the Parasitoid Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) for Medical, Veterinary and Economic Importance Collected in the State of Goiás, Brazil | Chapter 3 | Recent Research Advances in Biology Vol. 12

 Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) is a solitary parasitoid that feeds on Diptera from the families Anthomyiidae, Calliphoridae, Cecidomyiidae, Drosophilidae, Lonchaeidae, Muscidae, Phoridae, Piophilidae Pachycrepoideus vindemmiae is a parasitic Diptera parasitoid that feeds on Calliphora, Lucilia, Hylemya, Drosophila, Rhagoletis, Paratheresia, Anastrepha, Ceratitis, Phormia, Phaenicia, Sarcodexia, Zaprionus, Ornidia, Megaselia, Synthesiomyia, and Haematobia. This species has a wide range of distribution; it has been found in North America, Canada, Africa, and various Latin American, Asian, and European countries. The parasitoid P. vindemiae is studied in this book chapter in terms of its hosts, development in diverse substrates, geographical distribution, taxonomy, biology, types of traps and collecting methods, and an experimental research.
