Aluminum phosphide is known in our country as Phostoxin tablet. Human contact with Phostoxin tablet can have severe and fatal consequences. The present study aimed to evaluate and compare the group of patients dying due to Phostoxin tablet poisoning with the group that survived despite taking Phostoxin tablet.

This descriptive-analytical and cross-sectional study was performed on all patients poisoned with Phostoxin tablet in 2018 and 2019. The sampling method was a full census. According to the purpose of the study, T-test, Mann-Whitney, and Chi-square tests were employed in SPSS software version 24 and Graph pad prism version 8.

This study included 35 poisoned individuals with a mean age of  (16-82) years. The highest frequency was in the age group of 20-40 years (82.9%) and 21 women (60%) and 14 men (40%). There was a statistically significant relationship between mortality rate with drug use, length of hospital stay, blood pressure, number of breaths, level of consciousness, abdominal pain (P<0.05). Meanwhile, the mean level of ALT and AST liver enzymes and blood pressure in the two groups of dead and rescued were significantly different (P<0.05).

Phostoxin Tablet poisoning is a common cause of poisoning in Iran that has a high mortality rate. This is a serious health problem in communities where Phostoxin tablet is used. Consequently, you must go to the hospital immediately after contact with Phostoxin.

The cigarette beetle, Lasioderma serricorne damages a wide range of stored products. Despite a great deal of research, control of this pest still relies on the use of phostoxin tablets, which is becoming less effective as the insect develops resistance to this compound. In this research mortality effect of carbon dioxide and nitrogen gases evaluated individually and in combination, against adults of L. serricorne. Mortality was recorded after 24 h. Results indicated that nitrogen did not have a significant lethal effect on adults of pest. The LC50 value of carbon dioxide was estimated 2498.59 ppm. In combination tests of these gases, concentrations of 254, 381 and 508 ppm of nitrogen were combined with the LC50 value of carbon dioxide. Results showed that insect mortality was increased by decreasing the concentration of nitrogen or by increasing that of carbon dioxide. According to the results of this study, the cost of using phostoxin tablets was much higher than that of carbon dioxide. Linear programming can be introduced as a useful method for optimizing control managing of this pest. Also, by considering the low cost control and high insecticidal effect of carbon dioxide and evaluating other aspects, this fumigant can be introduced as a suitable alternative to phostoxin.

In this study, the control method of greater wax moth using male sterilization technique with gamma ray and chemical control methods were examined and compared. In order to determine the safe and effective dosage of gamma-ray to sterilize male pupae of the greater wax moth, an experiment was conducted in a complete randomized design with 5 treatments and 3 replicates with 50 male pupae in each replicate. Treatments included different levels of gamma-ray dosages with zero, 250, 300, 350 and 400 gray. Release ratio of sterile to normal males was also studied in a similar experiment. Treatments included sterile-males, normal males and virgin females with the ratios of 1:1:1, 2:1:1, 3:1:1, 4:1:1 and 5:1:1. In this study, male pupae were irradiated with 350 grays of gamma-ray. The possible parthenogenetic reproduction of this pest was also studied. In order to compare the results from the male-sterile technique and the chemical control of this pest, another experiment was conducted in wax stores using 3 treatments with 3 replicates. Phostoxin was used as the most common chemical pesticide with a dosage of 1 tablet of 3 grams of 56% per 1 m3 space for the control of this pest. The results showed that the best dosage to sterilize male pupae of the greater wax moth was 350 grays of gamma-ray. Also the best release ratio was four sterile male, one normal male for each normal female (4:1:1). Our results indicated that the females of the greater wax moth were not able to reproduce through parthenogenesis. There was no significant difference between the chemical and male-sterile methods for the control of this pest.
