“…Regarding the effect of relative humidity, the results showed negative insignificant effect of this factor on different stages of the mealybug which were in conformity with those of mentioned in certain studies (Mani, 1986;Mani and Thontadarya, 1987;Koli, 2003;Angu et al, 2017) who reported that M. hirsutis was profoundly affected by weather factors where relative humidity had significant negative effect on its incidence.…”

The presented work was carried out in a grapevine farms, at Fayoum Governorate, to shed the light on seasonal fluctuation at the population density of the striped mealybug, Ferrisia virgata Cockerell and the pink hibisicus mealybug, Maconellicoccus hirsutis Green (Pseudococcidae: Homoptera) as well as the effects of the main weather factors on the two insect population. Regular biweekly samples were taken for two successive years, from Nov. 2015 to Oct. 2017.The results indicated that all counted stages of the striped mealybug, F. virgata in the first season had two peaks on leaves of grapevine; 1 st peak was recorded at the end of Aug. and 2 nd one was recorded at the end of Sep. Regarding bunches of grapevines, only one peak was recorded in the first season at the end of Sep., in the second year, two peaks were recorded; the first peak was recorded at end of Jul. and the second one was recorded at the end of Aug..The population of M. hirsutis nymphs recorded one peak 130 nymphs/10 bunches at end of Sep.. Also, adult females recorded one peak at end of Aug. with 53 adult females/ 10 bunches while the total population of the mealybug recorded two peaks (in mid-Aug. and end of Sep.) to record 58 and 133 individuals/10 bunches. The results indicated that maximum and minimum temperatures had negative insignificant effects on nymphs, while showed positive insignificant effect on adult females and all individuals.

“…Also, it had three peaks were mid-July, mid-September, and mid-November when the population densities were (Goolsby et al 2002) mentioned that, the lowest populations densities of M. hirsutus (Green) were in rainy winter and the increasing on populations was in summer and autumn seasons. Also, (Angu et al, 2017) indicated that, lowest population of M. hirsutus (Green) was in July and mid of January.…”

Sapota, Manilkara zapota trees are very important tropical fruit which cultivated in many countries in the world. In recent years, Sapota trees have been cultivated in Giza, Egypt, because of their great nutritional importance. Sapota trees were attacked by many types of mealybugs, as five types were monitored and recorded: Maconellicoccus hirsutus, Planococcus citri, Ferrisia virgata, Phenacoccus solenopsis and Icerya seychellarum. The results of this investigation revealed that, M. hirsutus was the most dangerous of these insect pests that attack Sapota trees during the study seasons and we found that, the M. hirsutus peak population was recorded in early November 1701 individuals / 100 leaves during 2020-2021 and 1513 individuals / 100 leaves in 2021-2022 season. Also, we recorded three species of natural enemies were associated with M. hirsutus on Sapota trees. On the other hand, the impact of various temperatures on some biological aspects on immature stages and adult stages of M. hirsutus were studied. Durations of eggs, three nymph instars, pre -oviposition period, oviposition period and post-oviposition period were longest at 15° C and were lowest at 25 and 30° C. As well as longevity of females and males were lowest at 25 and 30° C and longest at 15°C. Fecundity of females was increased with increasing in temperatures. These results are important for improving the control of this insect and must be taken into account when developing an integrated pest management program.
