It was found that the disinfestation efficiency increased with the decrease in freezing temperature. For naked insects, complete mortality was achieved by the regimes at −20, −80, and −196 °C with the exposure time of 8 min, 2 min, and as short as 1 s, respectively.

Upon the increase in insect population density and package size, the longer exposure time was required for complete mortality. When the regime at −196 °C (1.5 min) was used as a pretreatment at −20 °C (60 min), the highest combination index (2.12) was obtained for the complete mortality.

Bioassays were conducted at both half-label and label doses across different post-exposure temperatures ranging from 20 to 35 °C. The results demonstrate that λ-cyhalothrin exhibits temperature-dependent efficacy within a 7-day exposure period, with higher temperatures resulting in increased mortality rates for both tested life stages.

The 11 varieties comprised nine dry date varieties collected from Aswan Governorate and Siwa Oasis, along with two semi-dry date varieties obtained from New Valley Governorate, Egypt. In a prototype, the efficacy of the EF/CO₂ (16.7%/83.3%, w/w) at 270, 420, and 670 g/m³ was evaluated against the most common insect species found in the date varieties. Moreover, the impact of fumigation by the EF/CO₂ (670 g/m³) on the quality parameters of Ghazali as dry and Elwadi-I as semi-dry date varieties was studied. The almond moth, <em>Ephestia cautella,</em> was the most abundant insect species, followed by the saw-toothed grain beetle, <em>Oryzaephilus surinamensis</em>, and the red flour beetle, <em>Tribolium castaneum</em>. The highest infestation percentage (43.7%) of <em>E. cautella</em> was recorded on Shamia variety, while the lowest infestation percentage (9.8%) was on Elwadi-Ⅱ variety. The Malkabi variety had the highest infestation percentage of <em>O. surinamensis</em> at 23.6%, while the Elwadi-Ⅱ variety had the lowest infestation percentage at 5.4%. The infestation percentages of <em>T. castaneum</em> were the lowest among insect species, ranging from 0.2 to 1.0%. The EF/CO₂ mixture was highly toxic to all life stages of the three insect species at all application rates, giving complete control at 420 and 670 g/m³. No significant differences in the quality parameters have been observed between untreated and treated samples of Ghazali and Elwadi-I varieties with EF/CO₂ at 670 g/m³.

The degree of dominance of these crosses ranged from 0.01 to 0.60, which falls under the scale of incomplete dominance. The analysis of log-dose probit curves along with the chi-square method of monogenic inheritance analysis of selfbred (F₂) and six backcross progenies revealed that resistance to permethrin was controlled by more than one gene. In summary, resistance to permethrin in the PR1-SO and PR2-SO strains was autosomally inherited with incomplete dominance and governed by more than one gene.

Argentina is one of the main producers and exporters of corn globally. Post-harvest pests, such as the insect <em>Sitophilus zeamais</em>, can cause losses of more than 10%, representing a very important negative economic impact on the industry. For pest control many synthetic insecticides are used. Nevertheless, these insecticides show toxicity to mammals and environmental contamination and cause resistance. For this, there is a constant need to introduce new substances used in the protection of crops and the plant extracts and their volatile products are an interesting alternative. In this work we evaluate the effectiveness of natural VACs for the control of <em>S. zeamais</em> and the prolonged effect of the more toxic alcohol incorporated in a paint on its survival. 1-heptyn-3-ol was the most toxic alcohol tested (LC₅₀ = 0.74 μL/L). In the presence of food, the fumigant toxicity of 1-heptyn-3-ol was lower (LC₅₀ = 14.73 μL/L). Also, the non-phytotoxic effect of 1-heptyn-3-ol was determined. When the 1-heptyn-3-ol was included in the polyvinyl paint, the toxic effect was prolongated in the time, causing even 80% mortality at 14th day. Regarding the repellent effect of 1-heptyn-3-ol, it was observed that this alcohol included in the bioactive paint, in the presence of food, presented a repellency similar to that determined for the pure compound, in the absence of food, and greater than the repellency determined for the pure compound in the presence of food. In conclusion, compounds such as 1-hetpyn-3-ol is a potential candidate for insecticidal formulations that allow adequate management of <em>S. zeamais</em> in stored grain.
