litchii, the developmental threshold temperatures ([degrees]C) and accumulated temperatures (degree-d) were: egg (14.3 [degrees]C, 66.7 degree-d), larva (14.8 [degrees]C, 31.7 degree-d), protonymph
(14.1 [degrees]C, 31.1 degree-d), deutonymph (13.0 [degrees]C, 36.1 degree-d), and entire generation (14.7 [degrees]C, 172.4 degree-d) (Table 3).
Paratypes: MEXICO: Veracruz: 1 [female], same data as holotype (CNAN-T1176), 1 [male], 1 protonymph
, 3 deutonymphs, 4 tritonymphs, same data as holotype (CNAN-T1177).
After the larvae eclosion, the duration, in days, of each mite developmental stage was observed: larvae, protonymph
, deutonymph, adult-egg period, and the longevity of males and females.
However, the protonymph
and deutonymph phases were similar at 25 and 30[degrees]C.
tanajoa was followed to adulthood, with daily observations of the larval, protochrysalis, protonymph
, deutochrysalis, deutonymph, teleiochrysalis, and adult stages to verify the succession to the next stage, as characterized by the presence of exuviae.
The life cycle of water mites is complex and includes the egg, larva, protonymph
, deutonymph, tritonymph, and adult.
The duration of the periods of larva (df= 107, t = 1.80, P = 0.07), protonymph
(df = 77, t = 0.40, P = 0.68), deutonymph (df = 66, t = 0.42, P = O.
The three nymphal instars are termed protonymph
, deutonymph, and tritonymph and can be easily recognized by the unique number of trichobothria of each stage .
The deutonymph or hypopus is a developmental instar of mites, and in H propus it is one of 5 juvenile stages including the prelarva, larva, protonymph
, deutonymph, and tritonymph.
The mean durations of larval, protonymph
, deutonymph of female and male stages were 1.10+-0.07, 0 1.02+-0.09 days; 1.10+-0.05, 0 1.07+-0.05 days; 1.03+-0.03, 0 0.96+-0.03 days respectively.
cocos comprised 3 inactive phases also viz., the first, second and third quiescent is between the larva and protonymph
and deutonymp, deutonymph and adult respectively.
Snake mites have a five-stage life cycle: egg, larva, protonymph
, deutonymph, and adult.
