Afternoon Calcium and Vitamin D Supplementation in Water: A Targeted Approach to Improve Laying Hen Nutrition.

A modified AM/PM strategy was evaluated in this study by supplementing calcium (Ca) in afternoon/evening (PM) drinking water instead of feed, offering an alternative to supplying two diets. A 10-week trial was conducted with 288 Hy-Line Brown hens (56 weeks old) housed on the floor in 18 pens (16 hens per pen; 9 replicate pens per treatment). The control diet contained 4.

Dataset of lecturer performance appraisel.

The dataset showed in this manuscript belongs to the investigation of determinant of lecturer performance in Indonesia. Semi-closed questionnaires were administered to collect data and 750 questionnaires were distributed by using snowball-sampling method to lecturers, peers, and students in the public and private universities in Indonesia. About 347 questionnaires were returned and could be further analyzed.

Evaluation of some non-invasive approaches for the detection of red palm weevil infestation.

Red palm weevil (RPW) causes severe damage to date palm trees, leading to the death of trees if not detected and treated in time. A major obstacle in RPW control is the difficulty in identifying an early stage infestation In the present study, we measured the efficacy of some non-invasive optical devices including cameras (digital camera and thermal camera), TreeRadarUnit™ (TRU) (Radar 2000, Radar 900), resistograph, magnetic DNA biosensor, and Near-infrared Spectroscopy (NIRS) to detect RPW infestation in date palm trees under field conditions at Riyadh, Saudi Arabia. Date palm trees used in these experiments were selected based on visual observations.

DNA barcoding of the fire ant genus Westwood (Hymenoptera: Formicidae) from the Riyadh region, the Kingdom of Saudi Arabia.

The ant genus Westwood, 1840 is the largest in Myrmicinae subfamily having almost 200 described species worldwide. They are commonly distributed in the tropics and temperate areas of the world. Some invasive species are very dreadful.

Evaluation of Natural Additives to Enhance the Persistence of Spodoptera littoralis (Lepidoptera: Noctuidae) Nucleopolyhedrovirus (SpliMNPV) Under Field Conditions in Saudi Arabia.

Nucleopolyhedrovirus is an effective biocontrol agent but for its biggest disadvantage of short persistence under sunlight conditions. In this study, 10 plant extracts were evaluated as ultraviolet (UV) protectants to improve the persistence of Spodoptera littoralis multiple-embedded nucleopolyhedrovirus (SpliMNPV) against cotton leafworm (Spodoptera littoralis Boisduval). In the primary lab screening test, 5 out of 10 additives (cloves, henna, green tea, pomegranate, and grape extracts) presented a high rate of virus protection with original activity remaining (OAR) percentage of 100%, 97%, 91%, 90.

Effectiveness of carbon dioxide against different developmental stages of Cadra cautella and Tribolium castaneum.

Methyl bromide is an excellent fumigant but has been banned because it has high potential for depleting the ozone layer which leads to many environmental and human health hazard issues. In this connection, effectiveness of carbon dioxide (CO, 99.9%) was studied as an alternative to methyl bromide under various exposure timings, 25 ± 1 °C, against different developmental stages of the almond moth, Cadra cautella, and red flour beetle, Tribolium castaneum.

Evaluation of artificial diets for Attacus atlas (Lepidoptera: Saturniidae) in Yogyakarta Special Region, Indonesia.

The objective of this research was to evaluate artificial diets that can be used to successfully culture the atlas silk moth, Attacus atlas L. (Lepidoptera: Saturniidae) indoors. Four plant species were evaluated as the basic component of each diet, barringtonia (Barringtonia asiatica), cheesewood (Nauclea orientalis), soursop (Annona muricata), and mahogany (Swietenia mahagoni).
