“…Despite the relative differences among experiments, overall results indicate that removal of surface residue over the seed zone at planting improves corn emergence and can help to reduce slug damage in no-tillage systems. Slugs are very sensitive to slight changes in soil moisture and need protective cover to survive higher temperatures during the day [ 8 , 24 , 25 ]. Studies have shown that cleaning residue from the seed zone increases soil temperature by 1.5 to 3 °C, resulting in faster germination and emergence of the corn seedlings [ 26 , 27 ].…”

Slugs, primarily the gray garden slug, Deroceras reticulatum (Müller), are the most damaging non-arthropod pest of corn grown in conservation tillage systems in the US. These mollusks favor decaying plant residue on the soil surface, which provides food, shelter and optimum microenvironmental conditions for their development and survival. Here, field plot experiments evaluated several cultural and chemical control practices to suppress slug activity and feeding injury during early seedling growth. The use of row cleaners to remove surface residue over the seed row and starter fertilizer applied different ways during planting significantly reduced the percentage and severity of plants damaged by slugs by negatively affecting their activity around emerging seedlings and providing more favorable conditions for plants to outgrow and tolerate feeding injury. As rescue treatments, reduced rates of a 4% molluscicide bait applied as a directed band over the seed row, and broadcasted solutions of urea-based nitrogen applied under calm winds at night provided effective slug control. Practical considerations of these treatments are discussed, as well as changes in weather patterns and current planting practices that have had contrasting effects on slug populations and their potential damage.

“…Adults’ snails of Eobania vermiculata were gathered by hand from Citrus limon trees during midden March 2022 from Buhaira Governorate. Animals were placed in transparent sacks and moved to the research center of the Zoology Agricultural and Nematology Department, Faculty of Agriculture, Al-Azhar University to be washed with freshwater ( Godan, 1983; Badawey, 2002 ).…”

“…Gastropods are invertebrates and hermaphrodites with spirally coiled bodies ( Srivastava, 1992; Zala, et al ., 2018 ). Land mollusks are extremely damaging pests of vegetables, field crops, ornamental plants, fruit trees, and ecosystems ( Godan, 1983; Carlsson, et al ., 2004 ). Several species of snails and slugs are considered pests in agroecosystems around the world due to their high reproductive potential, nocturnal activity, and feeding behaviors, which cause crop damage and economic loss ( Routray and De, 2016; Ali, 2017; Das, et al ., 2020 ).…”

Land snails are one of the most harmful agricultural pests to crops, causing economic devastation to a variety of plants. The purpose of this study is to determine the optimal food preference of land snails,Eobania vermiculata, and evaluate the mortality and biochemical activity of five pesticides using a leaf dipping technique against them in vitro. The findings revealed that in “no-choice feeding,” it was observed that land snails consumed a significantly higher amount of Cos lettuce leaves compared to leaves from other plants. However, chicory leaves were found to be the least preferred by the snails. On the other hand, “free choice feeding,” revealed that land snails showed a preference for Cos lettuce and cabbage leaves, which were consumed more frequently. Conversely, Komatsuna leaves had the lowest acceptance among the snails. Also, the results indicated the mortality rate increased with an increased concentration during exposure time. After three days, the lower concentrations of Sulfoxaflor and Fipronil caused a high mortality percentage in the animals compared with other pesticides, respectively. Moreover, after one month of exposure to 1000 ppm/100 ml, Chlorantraniliprole caused 46.43% mortality. But Sulfoxaflor and Fipronil exhibited (42.86%) mortality. They achieved LC50(1010.48, 2501.93, and 1444.66 ppm/100ml), against tested snails, respectively. Nevertheless, Spinetoram and Spirotetramat caused a lower mortality rate. During seven days of exposure to LC25for five pesticides by leaf dipping on E. vermiculata. They impacted some of the biochemical activity of two enzymes: alanine amino transaminase (ALT), aspartate amino transaminase (AST), total proteins (LP), and the lipid profile of E. vermiculata. The results showed that the activities of ALT, AST, and Triglycerides rose by 50%, with 108 u/l, 407 u/l, and 2064 mg/dl, respectively. Compared to the control and other compounds, Spirotetramat raised total cholesterol by 33 mg/dl. ALT and AST activity and Triglycerides lowered following Spinetoram and Fipronil treatment at 13 u/l, 32u/l, and (4 mg/dl) of TL, respectively. However, no substantial treatments or controls that influence TP, (Total cholesterol and LDH) or LP levels after the exposure period are available. Ultimately, the results indicated that both Cos lettuce and cabbage leaves were the preferred food choices for land snails, as observed in both feeding methods. However, it is important to note that these findings also highlight the need to consider the impact of insecticides on land snails. Incorporating these insecticides into a comprehensive management strategy to mitigate any negative effects of land snails while ensuring the overall well-being of the environment.

“…In the United States alone, insects are estimated to provide over $50 billion in ecological services ( Losey & Vaughan, 2006 ). Fireflies have great popular appeal and aesthetic and cultural value, but fireflies also contribute biological control of some pest species, including slugs and snails, which can be important agricultural pests ( Godan, 1983 ; Lewis, 2016 ). Human activities, however, have put these services at risk by triggering global insect declines ( Sánchez-Bayo & Wyckhuys, 2019 ).…”

Background Previous research suggests that fireflies (Coleoptera: Lampyridae) are susceptible to commonly used insecticides. In the United States, there has been a rapid and widespread adoption of neonicotinoid insecticides, predominantly used as seed coatings on large-acreage crops like corn, soy, and cotton. Neonicotinoid insecticides are persistent in soil yet mobile in water, so they have potential to contaminate firefly habitats both in and adjacent to application sites. As a result, fireflies may be at high risk of exposure to neonicotinoids, possibly jeopardizing this already at-risk group of charismatic insects. Methods To assess the sensitivity of fireflies to neonicotinoids, we exposed larvae of Photuris versicolor complex and Photinus pyralis to multiple levels of clothianidin-treated soil and monitored feeding behavior, protective soil chamber formation, intoxication, and mortality. Results Pt. versicolor and Pn. pyralis larvae exhibited long-term intoxication and mortality at concentrations above 1,000 ng g−1 soil (1 ppm). Under sub-lethal clothianidin exposure, firefly larvae fed less and spent less time in protective soil chambers, two behavioral changes that could decrease larval survival in the wild. Discussion Both firefly species demonstrated sub-lethal responses in the lab to clothianidin exposure at field-realistic concentrations, although Pt. versicolor and Pn. pyralis appeared to tolerate higher clothianidin exposure relative to other soil invertebrates and beetle species. While these two firefly species, which are relatively widespread in North America, appear somewhat tolerant of neonicotinoid exposure in a laboratory setting, further work is needed to extend this conclusion to wild populations, especially in rare or declining taxa.
