“…Cole crops are a major component in human diets. Many lepidopteran pests attack cole crops in various growth stages; the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae) and the cabbage butterfly, Pieris brassicae (Lepidoptera: Pieridae) are the most destructive among all (Firake et al, 2012a, Lytan and Firake, 2012). The caterpillars of both pest species feed voraciously on the leaves, defoliate the plants and make pesticidal applications obligatory in the cultivation of cole crops (Kulye et al, 2007, Firake et al, 2012b).…”

Lethal and sub lethal effects of fresh and old residues of azadirachtin, spinosad, var. ( var. ), and deltamethrin, were evaluated at their recommended field doses against adult and immature stages of under conditions. The experiments were carried out at the Entomology section of Division of Crop Protection, ICAR Research Complex for NEH region, Umiam, Meghalaya, in 2012-2013. The effects of different pesticides were determined by bioassays using the residual film method, the diet contamination method, the pupal dip method and the topical application technique. The four pesticides were found harmful to adult after ingestion, however surface contact bioassays revealed that var. was the least toxic pesticide. Except var., other three pesticides were found harmful also to the immature stages of and significantly affected parasitism potential, adult emergence, longevity of adults, and sex ratio of the progeny. Deltamethrin and azadirachtin were the most harmful, even after 15 days of application. Spinosad was found to be relatively safe to after 15 days of application. As appeared to be the least toxic pesticide for, it could be used for the management of severe infestations of lepidopteran pests in cruciferous ecosystems. If essential, spinosad may be used 15 days after parasitoid release, thus minimizing the chances of parasitoid exposure.

“…The brassicaceous ecosystems of Meghalaya harbour several natural enemies, many of them have a potential to reduce the pest damage (Firake et al, 2012a;Lytan and Firake, 2012;Firake et al, 2012b;Thubru et al, 2016). Among predators, the ladybird beetle, Coccinella septumpunctata Linnaeus (Coleoptera: coccinellidae) and syrphid flies, Episyrphus viridaureus (Wiedemann) and Betasyrphus isaaci (Bhatia) (Diptera: Syrphidae) are the major predators of mustard aphid in mid altitude hills of Meghalaya.…”

Basic biological attributes and feeding potential of three major predators viz., the seven spotted lady bird beetle Coccinella septempunctata Linnaeus and two syrphids Episyrphus viridaureus (Wiedemann) and Betasyrphus isaaci (Bhatia), of mustard aphid, Lipaphis erysimi were studied under laboratory conditions. The predators were multiplied on mustard aphids reared on mustard plants.C. septempunctata, E. viridaureus and B. isaaci completed their life cycle in 68.5± 6.5 days, 47±2 and 41±2, respectively. Coccinella septumpunctata completed the larval growth with four larval instars, while both the syrphids terminated the larval growth with three instars. Final instars of all the three predators were found to have highest predatory potential than the younger instars. C. septumpunctata was found to be the most dominant predator of mustard aphid with average lifetime consumption of 4312±537.74 aphids, followed by E. viridaureus (416.67±6.76 aphids) and B. isaaci (338±7.89 aphids). All the three predators have the potential to reduce the mustard aphids; however, C. septumpunctata has a maximum predatory potential with a longer life, which makes this species as an excellent bioagent of L. erysimi and further research on their utilization on a large scale should be undertaken.

“…However, to minimize the adverse effects of pesticides on natural enemies, there is an urgent need to assess and measure the risks of pesticides against natural enemies and identify the harmful insecticides. Pesticides may lethal to non-targeted organisms in addition to sub-lethal effects on behavioral and development of the bene cial insects, such as changes in rates of e ciency, longevity, sex ratio, and adult emergence (Cloyd R. A, 2012; Firake et al, 2012;Blibech et al, 2015).…”

This report gives an overview of the current situation of highly hazardous pesticides (HHPs) in North Africa and Near East countries (NENA). This work reviews the registered pesticides in the region and identify HHPs being used according to the Criteria 1-8 for HHPs of FAO/WHO Guidelines on HHPs. In addition, to identify the weakness and the need of the region to mitigate the risk from the use of HHPs, the report ended with recommendations needed in the region to improve the pesticide managements and registration, such as improving the agricultural practices by adopting the integrated pest management IPM and including replacing HHPs with ecosystem-friendly alternatives if available. The total number of pesticides registered and used in NENA region are 642 actives ingredients (IA). 89 HHPs are still in use in NENA region and 50% of them are evaluated under 1-7 criteria of GHS HHPs. This evaluation shows that 50% of HHPs are insecticides, 22% fungicides, 10% herbicides, 8% nematocides, 10% rodenticides. The rest of 38 HHPs are identi ed under criteria 8. This high number of HHPs still in use in some NENA countries urge the need technical assistance to reduce the use of HHPs. The type of assistant varies from country to other, to identify the priority of technical and legal assistant needed a country-based assessments must carry out at near future. IntroductionOver the last years, an abundance pesticides and uncontrolled use, with exposure and adverse health effects on human health and environment, have become a serious issue to be concerned, especially when the number of intentional and unintentional poisonings have been increased in the Low-and Middle-income countries (LMIC). In addition to serious environmental impacts such as undermining the biodiversity, destroy the bene cial insects and natural enemies in the ecosystems. The highly hazardous pesticides (HHPs) increased risks to people through indirect or direct contact during life cycle of pesticide, including production, handling, use, and even the obsolete products. It also causes adverse effects on food security from the contaminated vegetables and fruits. It is one of the major sources of water and soil pollution. Their continues use will adversely affects the sustainable agriculture scheme in LMICs. However, HHPs are limited in numbers but it causes most of the high poisonings and adverse effects on human health and the environment, particularly in low and middleincome countries. ". In 2015, the fourth session of the International Conference of Chemicals Management (ICCM4) of SAICM, adopted a resolution that recognized HHPs as an "issue of concern" and called for concerted action to address HHPs ( https://www.who.int/ipcs/features/hazardous_pesticides.pdf? ua=1). That global issue has been addressed by FAO, WHO and UNEP as well as those of many other public and private stakeholders active in the topic. Therefore, actions are needed on these HHPs, which is now widely known and there is no justi cation for waiting any longer before acting appropriately to b...
