“…Thus, organic molecules of botanical origin may offer a safe source of compounds for pest management, being environmentally friendly, and an excellent alternative to persistent synthetic insecticides (Biondi et al, 2006). Neem seed extract active ingredient azadiractin 1%, acts as antifeeding, deterrent and growth inhibitor against a number of insects and mites including tomato leaf miner (Marčić et al, 2009;Koul et al, 2004).…”

Tuta absoluta is the major insect invading tomato crop under greenhouse and open field conditions in Lebanon. Farmers mainly depend on chemical control to reduce damage caused by the larva. The hazard use of chemical agents can lead to resistance accumulation. The objective of this study is to investigate alternative agents like biopesticides to control this pest. Two field trials were conducted at the Lebanese Agricultural Research Institute (LARI) for two years under greenhouse conditions. In 2014, the first trial was conducted in two greenhouses: 1-control greenhouse without insect proof net (CG); 2-double door Greenhouse with insect proof net (DDG). In 2015, the second trial was conducted only in control greenhouse.Four treatments and control (not treated plot) were adopted in both trials. The biopesticides used in this study were Neem azal and Bacillus thuringiensis. Results of the first trial showed that using insect proof net reduced the captured adults on the water trap as compared with control greenhouse and thus reducing the damaged caused by the larva of tomato leaf miner on leaves and fruits. The adopted treatments have shown significant differences in the number of mines/leaf, live larva/leaf and percent of damaged fruits in both trials compared to the control. Applying Bacillius thuringiensis and neem azal separately and mixing them together have shown a promising alternative method to chemical control.

“…In comparison with T1 (Table 3), T2 (69%) and T3 (54%) had the lower efficiency in both observed years In the Czech Republic, Kocourek and Stara (2006) found that the efficiency of the tested preparations was also different from year to year and that it also differed in the application dates from 92 -100% for Vertimec, which was also used in our study as a part of T1 and T2. In a study conducted in Serbia (Maričić et al, 2009), diflubenzuron achieved the efficiency of 59%. It explains our efficient results for T1 from 84-95%, because each active ingredient in this treatment had its own different effectiveness, which also depends on the other abiotic factors (the time of application, year, etc.).…”

Cacopsylla pyri L. (Hemiptera: Psyllidae) is one of the most serious economic pear pests in Eastern Croatia. Previous methods of pear control in the Republic of Croatia have led to the development of an insect population resistant to certain active ingredients. The objectives of this two-year study were to determine the optimal number of treatments for psylla control based on the monitoring of pest life cycle and to determine the effectiveness of processed kaolin in controlling the pear psylla in comparison with other chemical insecticides in four different treatments (T1. IPM-integrated protection program – diflubenzuron, spirotetramat, abamectin, acetamprid; T2. acrinatrin + abamectin, T3. kaolin clay, T4. control treatment). The research was conducted in 2017 and 2018 in a six-year-old experimental pear orchard on three varieties (Williams, Conference, and Abate Fetel). Monitoring of the pest population and its development was performed by visual inspection on two one-year shoots per tree of each variety in all replicates. The T1 treatment demonstrated the highest efficiency, between 84-95%, depending on the year, while the kaolin treatment had the lowest one, but it varied greatly from one year to the other (37-71%).

“…It is the main pest of melons, technical plants, and horticulture, ornamental trees. More than 150 species of spiders have been reported as the main pests of crops around the world [8,9] . According to other scientists, the apple red mite (Panonychus ulmi Koch) is found in almost all agricultural areas of the world, and phytophagous mites are more plantrelated than all other mites [10] .…”

The article provides information on the harm and control methods of apple red mite (Panonychus ulmi Koch) in apple orchards. Apple red mite (Panonychus ulmi Koch) is the most dangerous pest of seed orchards and other crops of other European countries. This pest can destroy more than half of the crop yield in some fields. In normal years, spiders are said to destroy 6-10% of the gross crop, and in some years even 14%. Apple red mite (Panonychus ulmi Koch) is the most dangerous and harmful in terms of mites. It is the main pest of melons, technical plants, and horticulture, ornamental trees. More than 150 species of spiders in the world are listed as the main pests of crops. Materials and methods: New chemical Envidor em. k against apple red mite (Panonychus ulmi Koch) in seed orchards. To determine the biological effects of the drug (0.5 l/ha), research was conducted on 25 (twenty-five) hectares of Fuji apple orchards located on the territory of Zevar farm in Sariosiya district in the Surkhandarya region. Agrotoxicological experiments were carried out by the method of K.A.Gar, Sh.T.Khojaev. The calculation of biological efficacy in field and laboratory experiments was determined according to the W.S.Abbot formula, which takes into account the control option. Research results. According to research, the new Envidor em. k. (0.5 l/ha) was the highest on the 3 days of our observations in the variant in which the drug was used, i.e., the biological efficacy was 89.2%. Conclusion: Envidor em. k. high biological efficiency can be achieved by applying the drug at the rate of consumption per hectare (0.5 l/ha). The fight against apple red mite (Panonychus ulmi Koch) can be obtained the expected result by timely agro-technical measures in late autumn and early spring, the use of low-toxic chemicals for the environment, and beneficial insects during the growing season.
