“…Adult predators escaping from treated plants into other clean plants are either adjacent to the treated plots or moves to other far plants. This result was in agreement with that reported by Matter et al (2018Matter et al ( , 2019 and Gesraha and Ebeid (2019).…”

“…In addition, results explain that the difference between the sprayed tested plants was significantly affected by the mean numbers of the recorded predatory adults. Where marrow plant was heavily invaded by different insect and/or mite pests consequently comprised a large number of different examined predators, these findings agreed with that reported by Matter et al (2018Matter et al ( , 2019 and Gesraha and Ebeid (2019).…”

Background: Numerous predatory insects were recorded on different plants; some were fed on the floral nectar and others as visitors. Other insects used any plant as a shelter or associated with their prey. Pollinators and beneficial arthropods suffering from a wide range of chemical pesticides are used. So, seeking for safer alternatives is mandatory to conserve such beneficial arthropods. Sorell-98% is a sulphur formulation which was examined against some insect predators with minimal adverse impacts. Method: Agricultural Sorell-98% (commercial Sulphur formulation) was applied to protect many crops against some plant diseases and sucking insect pests (aphis, whiteflies, thrips) and mite pests as well. This formulation was applied at a rate of 30 kg/Feddan after 30 days of plantation. Two rectangular areas (ca. 700 m 2 each) were chosen to execute experiments. The first area was in a field which was sown with marrow plant, while the second was in an okra field. Each area was partitioned into four equal plots (ca. 75 m 2). Similar plots (third area) were done but received no treatments (second control area). Examination of the mean numbers of the natural enemies was recorded at several intervals and was achieved at 7 am. Samples of 50 plants were inspected-on spot-per plot/ time interval in the three experimental zones. The mean number of each predator/time interval and percentage of increase and/or decrease was calculated. Results: Results reveal that the abundance of the target predators was affected indirectly in different cultivated plants after sulphur application, as a result of different plant nature and consequently the population of pests invaded. At all inspection periods, it was observed that the mean numbers and abundance of adult predators on marrow plants was more than that reported in an okra field. Under all inspection times, there was a significant difference between the mean numbers of recorded predators, where Coccinella adults recorded the highest mean numbers, followed by Chrysoperla adults. Stethorus adults recorded the least mean number, either before or after sulphur application. Conclusion: The abundance of any arthropod predators is closely related with their favourable insect prey and did not relate to a certain plant by itself. The three tested adult predators were-to some extent-affliction from the sulphur application.

“…These obtained results matched those of Cabral et al (2011) when they evaluated the effects of pirimicarb and pymetrozine on the voracity of fourth instar larvae and adults of C. undecimpunctata. Results were agreed with those findings reported by Matter et al (2018 and, , when they applied sulphur formulation to study its effects on C. undecimpunctata larvae and adults. The obtained results matched those of Jalali et al (2009) when they evaluated the toxicity of some insecticides to the twospot ladybird, Adalia bipunctata in a laboratory study, and those of Roubos et al (2014) when they conducted a series of bioassays to determine the relative toxicities and residual activities of insecticides labelled for use in blueberry (Vaccinium corymbosum L.) on natural enemies, to identify products with low toxicity or short-duration effects on biological control agents.…”

Background For the sake of environmental safety, many new insecticide generations developed. Sulphur formulations and other botanicals or formulated synthetic insecticides were recommended in many integrated pest management programs to protect, particularly, edible vegetables and fruit trees from insect and mite pests as well as plant pathogenic diseases. Such formulations, at the recommended application rates, proved to be safer for mammals. Regarding their safety to beneficial arthropods, diversified results were reported. This study was designed to investigate and evaluate the impact of indoxacarb and sulphur formulation against some natural enemies naturally prevailing in some vegetable crops. Results Application of indoxacarb and sulphur formulation in Okra fields to control aphid was carried out. The adverse effects of these applications against some important predators were investigated. The obtained results revealed that indoxacarb was more effective than sulphur application in all treatments. At the end of the experiment, the percentages of population reductions of Coccinella indoxacarb treatment reached ≈ 92 and 76% for larvae and adults, respectively. The corresponding figures for Chrysoperla were ≈ 79 and 82% for larvae and adults, respectively. Indoxacarb-induced reduction in the Paederus population reached about 80%, while sulphur formulation had negative effects. Both indoxacarb and sulphur formulations were harmful to the aphid, inducing about 97 and 26% reduction, respectively, for the mean number of aphid populations. Conclusion It could be concluded that indoxacarb is more hazardous towards different natural enemies prevailing naturally in open fields at anywhere season round the year, and care must be in consideration when we choose and select some insecticides to kill or to eradicate pests and simultaneously conserve the natural enemies.
