The largest group of cabbage plant pests are the species in the owlet moth family (Lepidoptera: Noctuidae), the most dangerous species of which is the cabbage moth (Mamestra brassicae L.). In cases of heavy infestation by this insect, the surface of plants may be reduced to 30%, with a main yield loss of 10–15%. The aim of the present study was to assess the susceptibility of M. brassicae larvae to nine native nematode isolates of the species Steinernema feltiae (Filipjev) and Heterorhabditis megidis Poinar, Jackson and Klein under laboratory conditions. The most pathogenic strains were S. feltiae K11, S. feltiae K13, S. feltiae ZAG11, and S. feltiae ZWO21, which resulted in 100% mortality at a temperature of 22 °C and a dosage of 100 infective juveniles (IJs)/larva. The least effective was H. megidis Wispowo, which did not exceed 35% mortality under any experimental condition. For most strains, there were significant differences (p ≤ 0.05) in the mortality for dosages between 25 IJs and 50 IJs, and between 25 IJs and 100 IJs, at a temperature of 22 °C. Statistical analysis of the effect of temperature on mortality showed that only strain H. megidis Wipsowo exhibited significant differences (p ≤ 0.05) when applied at dosages of 50 IJs and 100 IJs.

Effect On Growth

The effectiveness of two application methods of the growth regulator paclobutrazol on the growth of Chrysanthemum plants, Dendranthema ×grandiflora (Ramat) (cv. `Fina' and `Cream Dana') were compared. Plants were grown in containers with their interior covered by a mixture of flat latex paint and several concentrations of paclobutrazol (0, 5, 10, 20, 40, 80, 100, 150, 160, and 200 mg·L–1) or were treated with a soil drench of the growth regulator according to label recommendations (59 ml/container of paclobutrazol solution at 4 mg·L–1). Plants grown in containers with the paint–paclobutrazol mix at concentrations >80 mg·L–1 were shorter than plants given the control and paint only treatments but taller than plants given the drench treatment. Increasing paclobutrazol concentrations in paint from 100 to 150 and 200 mg·L–1 did not produce proportionately shorter plants. Paint alone had no effect on growth and development. Plants subject to growth regulator treatments appeared greener than the control plants. None of the plants given treatments with paint with or without paclobutrazol showed any sign of phytotoxicity. These results suggest the possibility of a new application method for systemic chemicals with the potential of reducing or eliminating worker protection standard restricted entry intervals and reducing the release of chemicals to the environment. Chemical name used: beta-[(4-chlorophenyl)methyl]-α-(1,1-dimethyl)-1H-1,2,4,-triazole-1-ethanol (paclobutrazol).

Evaluation of various natural diets for mass rearing of Spodoptera frugiperda J.E Smith (Lepidoptera: Noctuidae). Spodoptera frugiperda is one of the pests that attack corn in Indonesia. This study aimed to evaluate the most suitable diet for rearing of S. frugiperda from various natural diets. The study was conducted in vitro. The treatments were consisted of variation on S. frugiperda natural diets, such as maize leaf, green mustard leaf, water spinach, sweet potato leaf, sugar cane leaf, and soybeans leaf. The observed variables were life cycle period, pupa size, and pupa weight. The results showed that the shortest life cycle period was on corn leaves diet (40.92 days), and the longest was on sugarcane leaves (45.01 days). The longest size of pupa were S. frugiperda on mustard leaves diet (12.86 mm) and corn leaves (12.56 mm), The heaviest pupa weights were observed in S. frugiperda on mustard leaves diet (0.18 mg), and corn leaves (0.16 mg). Based on the data, it could be concluded that corn leaves were the most suitable type of diet for the growth and development of S. frugiperda.

The gadget utilization among preschoolers in connection with technological advances is known to have positive and negative effects on growth and development. This study aims to identify the overview of gadget utilization and its effect on growth and development in preschool children. An analytic survey with a cross-sectional design was conducted by filling out questionnaires carried out by parents. The anthropometric measurements and developmental assessments were carried out using Indonesia Developmental Pre-screening Questionnaire (IDPQ). A hundred children and their parents participated in this study. It was found that 82% of parents lent their gadgets, and 89% taught their children to use gadgets. There were similarities in gadget utilization between parents and children, namely watching videos (73% and 90%) and communicating (92% and 40.4%). The duration of the gadget utilization by children was high, 3.7±2.2 hours/day. However, no significant correlation in the analysis between the duration of smartphone usage and nutritional status (p: 0.599). In children with different IDPQ values, there was no significant difference in the duration of device usage (p: 0.991). It can concluded the duration of the gadget utilization in children carried out by their parents did not affect the growth and development of the children.
